For a business to be profitable, it must cut out waste and inefficiency, yet not all businesses fully adopt this approach. Lean methodology provides a solution, proposing a system through which businesses can reduce waste by fostering ongoing feedback cycles, review, and learning, thus enhancing efficiency and becoming "lean." This approach aims to deliver valuable, cost-effective, and competitively priced services, ensuring customer satisfaction.

Lean methodology is a systematic approach to continuous process improvement through the elimination of waste. It originated in the manufacturing industry, specifically within Toyota, in the mid-20th century as part of the Toyota Production System (TPS), which sought to maximize value for the customer through the optimal use of resources. The principles of Lean have since been adapted and applied across various sectors, including healthcare, software development , and service industries.

The evolution of Lean methodology can be seen as a series of adaptations from its origins in manufacturing to its application in diverse fields:

• Origins in Manufacturing: The roots of Lean can be traced back to the Toyota Production System, which was developed by key figures like Sakichi Toyoda, Kiichiro Toyoda, and Taiichi Ohno. The system emphasized efficiency, quality, and eliminating waste (muda), which included unnecessary steps, excess inventory, and defects.
• Spread to Other Industries: As the success of the TPS became evident, other industries began to take notice. By the late 20th century, Lean principles were adapted for use in other fields, including construction, healthcare, and IT. Each sector tailored the Lean principles to suit its unique challenges and processes.
• Lean Six Sigma: Integrating Lean methodology with Six Sigma practices, which focus on reducing process variation and improving quality, further evolved the approach. This combination, called Lean Six Sigma, aims to create more customer value by improving quality, speed, and cost.
• Digital Transformation and Agile: In software development and IT, Lean principles have merged with Agile methodologies to enhance flexibility, responsiveness to customer needs, and the rapid and efficient delivery of high-quality products.
• Continuous Innovation and Learning: Today, Lean methodology continues to evolve with a strong emphasis on continuous learning, innovation, and adaptation to the changing business landscape. It focuses on process improvements and fostering a culture of empowerment among employees, encouraging them to contribute to continuous improvement.

Lean methodology principles are fundamental guidelines that help organizations focus on value creation while minimizing waste. The five core principles of Lean methodology are designed to improve efficiency, quality, and customer satisfaction. They are:

• Define Value: The starting point of Lean is to specify value from the standpoint of the end customer. Understanding what the customer values in a product or service allows organizations to streamline their processes, ensuring that every action contributes towards fulfilling the customer's needs and expectations.
• Map the Value Stream: This principle involves identifying and mapping all the steps involved in delivering a product or service, from raw materials to the final delivery to the customer. The goal is to visualize the flow of materials and information throughout the organization. This mapping helps identify and eliminate non-value-adding activities (waste), ensuring that every step in the process adds value to the product or service.
• Create Flow: Once the value stream is identified, the next step is to ensure that the value-creating steps occur in a tight sequence, allowing the product or service to flow smoothly toward the customer without interruptions, delays, or bottlenecks. This can involve reconfiguring production steps, leveling workload, creating cross-functional teams, or adopting new technologies to enable a seamless flow of products and services.
• Establish Pull: Instead of pushing products through production based on forecasted demand, Lean dictates that production should be based on actual customer demand, thereby minimizing waste associated with overproduction and excess inventory. A pull-based system allows for a more responsive and flexible production scheduling and inventory management approach.
• Pursue Perfection: Lean is an ongoing process of continuous improvement. Pursuing perfection involves continually seeking ways to reduce waste and improve processes, thereby maximizing value for the customer. This principle encourages a culture of continuous learning and improvement, where employees at all levels identify inefficiencies and suggest improvements.

There are eight commonly recognized forms of waste in the Lean methodology:

• Defects: Errors or defects in products or services that require rework or correction, leading to waste through additional time, resources, and effort to fix the issues. This not only increases the cost of production but also delays the delivery to the customer.
• Overproduction: Producing more products than needed by the next process or the customer leads to excess inventory , tying up resources and space that could be used more productively.
• Waiting: Time during which work is not being done, or value is not being added, often due to bottlenecks, imbalances in workloads, or delays in processes. This can include waiting for materials, information, or equipment.
• Non-Utilized Talent: Underutilizing people’s skills, talents, and knowledge wastes potential and can lead to employee dissatisfaction. Engaging and empowering employees can lead to more innovative and efficient processes.
• Transportation: The unnecessary movement of products or materials between processes adds no value to the product but increases the risk of damage, delays, and costs.
• Inventory: Excess products and materials not being processed create storage challenges, tie up capital, and risk obsolescence or damage, leading to further waste.
• Motion: Unnecessary movements by people (e.g., reaching, walking, or bending) that do not add value to the product or service. Efficient workspace layout and ergonomic considerations can help reduce this form of waste .
• Extra-Processing: Doing more work or adding more features to a product than what is valued by the customer. This can stem from poor process design, unclear customer requirements, or over-engineering.

Agile and Lean methodologies are often discussed in software development, project management , and organizational efficiency. While Agile originated in the software development field as a response to the limitations of traditional waterfall project management methodologies, Lean comes from the manufacturing sector, particularly the Toyota Production System.

Despite their different origins, Agile and Lean share several core principles and philosophies that complement each other. Here are some of the key similarities between Agile and Lean methodologies:

1. Customer Value Focus

Both methodologies prioritize delivering value to the customer. Lean emphasizes understanding and delivering what the customer values by defining value from the customer's perspective. Agile focuses on customer collaboration and responding to customer feedback to ensure the end product is valuable to the customer.

2. Emphasis on Flexibility and Responsiveness

Agile and Lean both advocate for adaptability and responsiveness to change. Agile methodologies like Scrum or Kanban encourage teams to adapt quickly to changing requirements and environments. Similarly, Lean promotes flexibility in production processes to respond efficiently to customer demand and reduce waste.

3. Continuous Improvement

Continuous improvement is both Agile and Lean’s core principle. Agile methodologies incorporate regular retrospectives and iterative development to improve the product, process, and team performance continually. Lean uses the concept of Kaizen, or continuous improvement, to systematically reduce waste and improve efficiency and quality.

4. Elimination of Waste

While Lean explicitly focuses on identifying and eliminating waste (or "Muda") in processes, Agile also seeks to reduce waste, albeit indirectly, by minimizing unnecessary documentation, reducing over-engineering, and avoiding tasks that do not contribute directly to customer value.

5. Empowerment of Teams

Both methodologies emphasize the importance of empowering teams. Lean encourages involving everyone in identifying inefficiencies and suggesting improvements, fostering a culture of empowerment. Agile methodologies prioritize self-organizing teams that can make decisions rapidly and collaboratively.

6. Incremental and Iterative Work

Agile and Lean advocate for breaking down work into smaller, manageable pieces. Agile does this through iterative development cycles (sprints), delivering small increments of the product regularly. Lean achieves this by ensuring work flows smoothly and efficiently, often utilizing pull systems like Kanban to manage work in progress and deliver value incrementally.

7. Emphasis on Quality

Quality is a key focus in both methodologies. Agile methodologies incorporate quality assurance practices throughout the development process, ensuring quality is built into the product. Lean similarly emphasizes the importance of quality, aiming to do things right the first time to avoid waste associated with defects and rework.

8. Use of Visual Management Tools

Both Agile and Lean use visual tools to manage work and process flow. For example, Kanban boards are used in Agile and Lean to visualize work in progress, streamline workflow, and identify bottlenecks.

Agile and Lean methodologies share common principles but also have distinct differences, especially in their areas of focus and application contexts. Below is a table summarizing some of the key differences between Agile and Lean methodologies:

Lean software development extends the principles of Lean manufacturing and management to the software development process, adapting its core tenets to focus on value, efficiency, and eliminating waste in the development cycle. By applying Lean principles, software development teams aim to deliver high-quality software faster and more efficiently while being more responsive to customer needs. Here are key capabilities and practices in Lean software development:

1. Eliminate Waste

In software development, waste refers to any activity that does not add value to the customer. This includes unnecessary code, documentation, waiting times, task switching, and defects. Lean emphasizes identifying and eliminating these wastes to streamline the development process.

2. Amplify Learning

Software development is a continuous learning process. Lean encourages practices such as code reviews, pair programming , and iterative development cycles to facilitate constant learning and improvement. Teams are encouraged to experiment and learn from successes and failures alike.

3. Decide as Late as Possible

Lean software development advocates for delaying decisions until the last responsible moment. This approach allows for more flexible and informed decision-making, taking advantage of more up-to-date information and reducing the risk of costly changes.

4. Deliver as Fast as Possible

Speed and efficiency are core to Lean. This capability focuses on reducing the time from customer request to delivering a feature, known as the lead time. Continuous Integration (CI) and Continuous Deployment (CD) help automate and streamline the development process, enabling faster releases and quicker feedback loops with customers.

5. Empower the Team

Lean promotes giving autonomy to development teams, trusting them to make decisions and solve problems within their domain. This empowerment boosts morale and encourages a sense of ownership, which can lead to more innovative solutions and improvements in the development process.

6. Build Integrity In

Software integrity refers to the cohesion and overall quality of the software product, including its usability, maintainability, and functionality. Lean advocates for building quality into the product from the beginning through practices like Test-Driven Development (TDD), automated testing, and refactoring. This ensures the product meets customer needs and reduces the need for rework.

7. Optimize the Whole

Instead of focusing solely on individual components or stages of development, Lean emphasizes optimizing the entire value stream, from idea to delivery. This approach encourages teams to break down silos and collaborate across functions to improve the flow of work and ensure that efforts are aligned with delivering customer value.

8. Use of Lean Tools

Tools like Kanban boards and Value Stream Mapping are used to visualize work, manage flow, and identify bottlenecks in the software development process. These tools support Lean principles by making the process more transparent and helping teams focus on continuous improvement.

1. Manufacturing: Streamlining Production Lines

Challenge: A manufacturing plant faced issues with production bottlenecks, excess inventory, and long lead times, leading to delayed deliveries and increased costs.

Lean Solution: The plant implemented several Lean tools, including Value Stream Mapping, to identify and eliminate non-value-adding steps in production. They introduced a Kanban system to manage inventory better and align production with actual demand, and they reorganized the layout of the production floor to minimize unnecessary movement (transportation waste).

Outcome: These changes led to a smoother flow of materials through the production line, reduced inventory levels by 30%, improved on-time delivery rates, and significantly decreased lead times.

2. Healthcare: Improving Patient Flow in Emergency Rooms

Challenge: An emergency department (ED) faces long waiting times, patient dissatisfaction, and staff stress due to overcrowded conditions and inefficient patient flow.

Lean Solution: The ED used Lean methodologies to map the patient journey and identify bottlenecks. They then implemented changes such as standardizing intake processes, optimizing staff allocation based on peak times, and establishing fast-track lanes for patients with minor conditions.

Outcome: The changes reduced average patient waiting times by 40%, improved patient satisfaction scores, and improved staff morale, allowing for more efficient resource use and reduced crowding.

3. Software Development: Accelerating Feature Delivery

Challenge: A software development team struggled with slow release cycles caused by lengthy QA processes, code integration issues, and frequent rework.

Lean Solution: The team adopted Lean principles, implementing Continuous Integration (CI) and Continuous Deployment (CD) practices to automate testing and deployment. They used Kanban to manage workflow and limit work-in-progress, which helped identify and address bottlenecks more efficiently.

Outcome: These adjustments significantly reduced the time from code commit to deployment, with release cycles shortening from months to weeks. Faster feedback and correction loops also improved the overall quality of the software.

4. Retail: Enhancing Customer Service and Inventory Management

Challenge: A retail chain was experiencing high levels of stockouts and overstock in various locations, leading to lost sales and high inventory costs.

Lean Solution: The retailer applied Lean tools to analyze their supply chain and inventory management processes. They implemented a pull-based replenishment system, supported by accurate demand forecasting and real-time inventory tracking, to ensure that stock levels were aligned with actual sales patterns.

Outcome: Implementing these Lean principles resulted in a 50% reduction in stockouts, decreased excess inventory, and improved customer satisfaction due to the higher availability of products.

Value Stream Mapping (VSM) is a critical tool within Lean manufacturing that helps visualize and understand the flow of materials and information as a product goes through the value stream. Value Stream Mapping contributes to Lean manufacturing by:

• Providing a Visual Overview: It offers a clear visual representation of the flow of materials and information, making it easier to identify bottlenecks and waste.
• Facilitating Team Collaboration: Creating a value stream map encourages cross-functional collaboration and a shared understanding of the process.
• Highlighting Opportunities for Improvement: By mapping out the current state, organizations can more easily envision a future state with reduced waste and improved efficiency.
• Supporting Continuous Improvement: VSM is not a one-time activity but a tool for ongoing improvement efforts, helping organizations continuously refine and optimize their processes.

From manufacturing to healthcare and software development to retail, Lean principles empower organizations to streamline operations, enhance efficiency, and deliver unparalleled value to customers. Lean methodology optimizes processes and fosters a culture of excellence and innovation by focusing on waste elimination, continuous improvement, and value creation.

The Lean Six Sigma Expert course offers a great pathway for professionals and organizations eager to master these principles and drive significant operational improvements. This master's program provides an in-depth exploration of Lean and Six Sigma methodologies, equipping participants with the tools and knowledge to lead and sustain Lean transformations in their organizations.

Explore Lean Thinking and Practice / What is Lean?

What is Lean?

Lean is a way of thinking about creating needed value with fewer resources and less waste. and lean is a practice consisting of continuous experimentation to achieve perfect value with zero waste. lean thinking and practice occur together..

Lean thinking always starts with the customer. What does the customer value ? Or, stated differently and in a way that invites concrete action, what problem does the customer need to solve?  

Lean practice begins with the work — the actions that directly and indirectly create value for the customer — and the people doing that work. Through ongoing experimentation, workers and managers learn by innovating in their work — be it physical or knowledge work — for increasingly better quality and flow, less time and effort, and lower cost. Therefore, an organization characterized by lean practice is highly adaptive to its ever-changing environment when compared to its peers because of the systematic and continuous learning engendered by lean thinking and practice . 

A lean enterprise  is organized to keep understanding the customer and their context, i.e., specifying value and looking for better ways to provide it: 

• through product and process development,  
• during fulfillment from order through production to delivery, and 
• through the product’s and/or service’s use cycle from delivery through maintenance and upgrades to recycling.  

Lean Transformation Framework

Lean enterprises, both ongoing firms and startups, endlessly address fundamental questions of purpose, process, and people : 

• What is the value-driven purpose? Or what is the problem to solve? 
• What is the work to be done (to solve the problem)? 
• What capabilities are required (to do the work to solve the problem)? 
• What management system — operating system and leadership behaviors — is required? 
• What basic thinking, including mindsets and assumptions, are required by the organization as a purpose-driven socio-technical system? 

Lean thinking has a moral compass: respect for the humanity  of customers, employees, suppliers, investors, and our communities with the belief that all can and will be better off through lean practices. Lean is not dogmatic. It’s not a rigid, unchanging set of beliefs and methods. Instead, it progresses in the context of specific situations. There is no endpoint as long as value is imperfectly created, and waste exists.  Learn about the brief history of lean thinking and practice .

Let’s elevate the work. Celebrate it. And, with that, let’s treat it—the work—with the deep respect it deserves. – John Shook

How can lean thinking help you?

From executive  coaching  in strategy development, deployment, and alignment to engaging employees to create a culture of problem-solving and everything in between, see how lean thinking and practice can elevate your organization’s performance.

The five principles of lean.

by Doanh Do

5th August 2017

Lean was born out of manufacturing practices but in recent time has transformed the world of knowledge work and management. It encourages the practice of continuous improvement and is based on the fundamental idea of respect for people. Womack and Jones defined the five principles of Lean manufacturing in their book “The Machine That Changed the World”. The five principles are considered a recipe for improving workplace efficiency and include: 1) defining value, 2) mapping the value stream, 3) creating flow, 4) using a pull system, and 5) pursuing perfection. The next sections provides a detailed overview of each principle.

The Five Lean Principles Explained:

Figure 1. The Five Lean Principles

1. Define Value

To better understand the first principle of defining customer value, it is important to understand what value is. Value is what the customer is willing to pay for. It is paramount to discover the actual or latent needs of the customer. Sometimes customers may not know what they want or are unable to articulate it. This is especially common when it comes to novel products or technologies. There are many techniques such as interviews, surveys, demographic information, and web analytics that can help you decipher and discover what customers find valuable. By using these qualitative and quantitative techniques you can uncover what customers want, how they want the product or service to be delivered, and the price that they afford.

2. Map the Value Stream

The second Lean principle is identifying and mapping the value stream. In this step, the goal is to use the customer’s value as a reference point and identify all the activities that contribute to these values. Activities that do not add value to the end customer are considered waste. The waste can be broken into two categories: non-valued added but necessary and non-value & unnecessary. The later is pure waste and should be eliminated while the former should be reduced as much as possible. By reducing and eliminating unnecessary processes or steps, you can ensure that customers are getting exactly what they want while at the same time reducing the cost of producing that product or service.

3. Create Flow

After removing the wastes from the value stream, the following action is to ensure that the flow of the remaining steps run smoothly without interruptions or delays. Some strategies for ensuring that value-adding activities flow smoothly include: breaking down steps, reconfiguring the production steps, leveling out the workload, creating cross-functional departments, and training employees to be multi-skilled and adaptive.

4. Establish Pull

Inventory is considered one of the biggest wastes in any production system. The goal of a pull-based system is to limit inventory and work in process (WIP) items while ensuring that the requisite materials and information are available for a smooth flow of work. In other words, a pull-based system allows for Just-in-time delivery and manufacturing where products are created at the time that they are needed and in just the quantities needed. Pull-based systems are always created from the needs of the end customers. By following the value stream and working backwards through the production system, you can ensure that the products produced will be able to satisfy the needs of customers.

5. Pursue Perfection

Wastes are prevented through the achievement of the first four steps: 1) identifying value, 2) mapping value stream, 3) creating flow, and 4) adopting a pull system. However, the fifth step of pursuing perfection is the most important among them all. It makes Lean thinking and continuous process improvement a part of the organizational culture. Every employee should strive towards perfection while delivering products based on the customer needs. The company should be a learning organization and always find ways to get a little better each and every day.

Applying the Principles

The five Lean principles provide a framework for creating an efficient and effective organization. Lean allows managers to discover inefficiencies in their organization and deliver better value to customers. The principles encourage creating better flow in work processes and developing a continuous improvement culture . By practicing all 5 principles, an organization can remain competitive, increase the value delivered to the customers, decrease the cost of doing business, and increase their profitability.

His approach combines practical experience with a deep understanding of business fundamentals to drive meaningful change.

Lean Principles, rooted in the Toyota Production System, represent a transformative approach to business efficiency and customer value creation. These principles are not just a set of guidelines but a comprehensive methodology for process improvement and waste minimization. Central to Lean is the idea of delivering more value to customers using fewer resources.

This guide delves into the core principles of Lean – Identify Value, Map the Value Stream, Create Flow, Establish Pull, and Seek Perfection – and explores their practical applications in various business contexts. It also outlines a structured approach to implementing these principles, ensuring a sustained and impactful transformation in organizational processes.

What are the Lean Principles?

The Principles of Lean are fundamentally about creating more value for customers with fewer revenues. The Lean Principles originated from the Toyota Production System (TPS), These principles are clear sets of guidelines and techniques aimed at improving processes, minimizing waste, and therefore resulting in an overall increase in customer value.

The Five Principles of Lean are: 1. To Identify Value, 2. Mapping the Value Stream, 3. Creating Flow, 4. Establishing a Pull System, and 5. Seeking Perfection.

The reality is that in any production process, only a small percentage of activities are value-added from the customer’s point of view.

For example: in a bakery, value-adding activities include baking and decorating cakes, which directly meet customer needs. However, time spent waiting for ingredients to arrive or excessive inventory management is non-value-adding , as they don’t contribute directly to the creation or enhancement of the final product for the customer.

Identifying and eliminating or reducing the impact of non-value-adding activities is key to businesses being Lean. These non-value-adding activities are referred to as waste, or the Japanese term “ muda ,” and are known by eight popular categories: transportation, inventory, motion, waiting, overproduction, overprocessing, defects, and skills.

Lean Principles are industry-agnostic, meaning they can be applied to any business or process and are not just suitable for the automotive sector. Over the past 70 years, there have been plenty of examples of Lean being implemented in diverse sectors such as healthcare, software development, retail and service businesses. 

The Five Core Lean Principles

1. Identify Value

The first core principle of lean is Identifying Value , this is rooted in a deep understanding of what the customer truly values. It is not about what the business thinks is valuable, but what the customer perceives as valuable from your product or service.

An example of this might be:   A service industry, like a hotel, which might analyze customer feedback to prioritize amenities and services that guests value the most.

To understand more about identifying customer value, take a look at our Critical to Quality (CTQ) guide.

2. Map the Value Stream

The second principle of lean is mapping the value stream. This involves conducting a full analysis of the entire process flow, identifying each action taken in the course of creating and delivering a product or service.

Common tools used in the step include:  flow charts or value stream maps . For example, a manufacturer would chart the journey from raw materials to finished goods, identifying any step that doesn’t add value, like unnecessary movement of materials or delays in production.

To understand more about creating a value stream map, take a look at our Value Stream Map (VSM) guide.

3. Create Flow

The third principle of lean is to create flow. This is a key step that involves ensuring the identified value-added steps flow in an efficient sequence and ensuring that the product or service flows smoothly without interruption.

This could involve redesigning a workspace for efficiency, cross-training employees for greater flexibility, or adopting just-in-time inventory to ensure materials are available exactly when needed.

4. Establish Pull

The fourth principle of lean is to establish a pull system. A pull system aims to produce only what the customer needs and when they need it. This is in contrast to the traditional push system in which most businesses operate, where products are made in anticipation of demand. However, the nature of holding excess stock in inefficient and not a lean method to run a business.

5. Seek Perfection

Finally, the fifth principle of lean is to seek perfection. The pursuit of perfection is an ongoing process of continuous improvement, often referred to as Kaizen . This involves constantly looking for ways to make processes more efficient and effective in delivering value. This could mean regular brainstorming sessions for process improvement, continuous training programs, or implementing a feedback loop where employees are encouraged to suggest improvements.

Implementing the Lean Principles in an Organization

Implementing Lean principles in an organization is a transformative process that requires strategic planning, dedicated involvement from all levels of staff, and a commitment to continuous improvement.

Step 1: Assessment and Planning

Before implementing the lean principles, it is important to understand and assess the current state of the business processes. This step would involve mapping out the current process with a process map or value stream map from start to finish and identifying inefficiencies, redundancies, and any steps that do not add value to the customer. 

Take the following image as an example of the potential current and future states of the process. This theoretical visualisation is always the aim with the lean principles to reduce and remove as much waste as possible from the process and increase customer value. 

Value add analysis example

Key to the success of the assessment and planning of implementing lean is engaging and involving all relevant stakeholders in the process, including leadership, employees and possible customers, to ensure there is a clear understanding of the process and to secure buy-in for lean initiates to follow.

Step 2: Training and Engagement

A vital element to the success of implementing lean in a business, and in my experience, often the most overlooked element, is training and engagement. Educating employees about lean principles and methodologies is important. Furthermore, this should involve more than just theoretical knowledge but also practical insights into how these principles can be applied to their specific roles, making the role relevant to them. 

The goal of training and education should be to develop a culture where lean thinking becomes natural to them. This includes problem-solving , waste reduction, and continuous improvement.

This can be achieved by using engagement strategies such as workshops, seminars, and my favourite hands-on training sessions on real workplace problems. In effect, learners learn by doing while being guided by a qualified facilitator. 

Step 3: Pilot Projects

Once you have the foundations of areas to be improved and a team that is trained and engaged, the next step is to start improving with small pilot projects. The key is to start small and expand as confidence and competency in the business grow.

Once those initial projects have been completed and stakeholders see visible results this will further help develop the culture of lean. Going big on projects that fail will only increase resistance to future projects.

Use these pilot projects as learning experiences. Gather data, analyze results, and understand what works and what doesn’t. After successful pilot projects, plan to scale up lean implementations to more extensive areas or other processes within the organization.

Step 4: Continuous Monitoring and Adaption

Step three was just the start of a never-ending cycle of improvement, therefore, step 4 is about continuous monitoring and adaption. The business should continue to regularly monitor the progress of lean initiatives and use key performance indicators (KPIs) to measure success and identify areas for improvement.

You should encourage feedback from employees and customers.This feedback is valuable for understanding the impact of changes and uncovering new areas for improvement. You should also be prepared to adapt strategies and approaches based on the results and feedback. Lean is about continuous learning and adaptation.

Step 5: Building a Lean Culture

Finally and constantly, you should continue to develop a lean culture in the business, as lean is not a quick fix but a long-term commitment that requires long-term effort and dedication.

To ensure this is successful, leadership must actively support and participate in lean initiatives and set an example for the rest of the organization. Additionally, employees should be empowered to take initiative, suggest improvements, and make decisions that align with Lean principles. Lean thinking should be integrated into every aspect of the organization, from daily routines to strategic decisions.

Implementing Lean Principles is a journey of continuous improvement, requiring a strategic approach and a commitment to cultural change within an organization. It begins with a thorough assessment and planning, identifying areas of waste and inefficiencies. The process then evolves through training and engaging employees, undertaking pilot projects, and continuously monitoring and adapting strategies.

Ultimately, the success of Lean implementation lies in embedding these principles into the organizational culture, fostering a mindset of efficiency, customer focus, and perpetual improvement. Through this journey, businesses can achieve remarkable improvements in process efficiency, customer satisfaction, and overall value creation.

Q: What is the first step in implementing Lean in my organization?

A: The first step in implementing Lean is conducting an educational assessment to gauge the current level of Lean knowledge within your organization. This will help you identify knowledge gaps and form the basis for targeted training and education.

Q: How do I identify 'Value' as per Lean principles?

A: Identifying ‘Value’ in Lean involves understanding what the customer considers valuable. This can be achieved through customer surveys, interviews, and data analysis. The aim is to discern what the customer is willing to pay for, and then focus your efforts on delivering that value efficiently.

Q: Can Lean principles be applied to service industries like healthcare?

A: Absolutely, Lean principles are not confined to manufacturing and can be applied across various sectors, including service industries like healthcare. For example, Virginia Mason Medical Center successfully implemented Lean to reduce patient wait times and improve safety protocols.

Q: What metrics can be used to measure the success of a Lean project?

A: metrics for measuring lean success vary depending on the objectives. however, common key performance indicators (kpis) include cycle time, defect rates, customer satisfaction scores, and operational costs. these metrics help quantify the improvements achieved through lean implementation., q: is lean only about cost-cutting.

A: While cost savings are often a benefit, Lean is not solely about cutting costs. The primary focus of Lean is to create value for the customer by streamlining processes and eliminating waste. This often leads to increased efficiency, improved quality, and enhanced customer satisfaction, in addition to cost savings.

Lean 101: Understanding the Basics of Lean Thinking and Methodology — What is Lean?

New to lean we'll try to help define lean.

… for healthcare, manufacturing, and other settings.

“Lean Healthcare” Overview:

Download the 1st Chapter of Lean Hospitals

If you're visiting the blog because of a search and you're not sure what this whole “Lean” thing is about, we'll try to introduce you. Keep in mind that this is just a starting point. There's a reason that dozens of books have been written about Lean. It's not easy to fully understand all in one night. I have been learning about it for more than 15 years 20 years since 1994. Not that I'm holding myself up as the #1 expert on the topic. I learn about Lean every day and I try to get better by “ Practicing Lean .”

The Typical Goals of Lean

The goals of organizations that are practicing Lean are pretty consistent across industries. Their goals are to simultaneously improve:

• Delivery (reducing delays & waiting through a process)

The goal is to provide long-term success for an organization and for everybody involved — customers, employees, owners, suppliers, and other stakeholders.

In manufacturing, “delivery” might mean on-time delivery, or shipping the right product in the right quantity at the right time. In healthcare, it means providing the right care at the right place at the right time, which means reducing waiting times for appointments and reducing waits and delays when in a healthcare facility.

What Lean Is and Is Not

Lean is not about being skinny and it's not about “cutting to the bone.” Lean is about having the right resources in place to do the right work for the customer, with the right quality, at the right time.

Lean is not “mean” (although the words rhyme, unfortunately). Lean is respectful toward everybody who participates in a system, including customers, employees, suppliers, the community, etc.

Lean does not mean cutting heads in the name of cutting costs (see “Lean is not mean”). Lean is probably the best alternative strategy to the old approach of layoffs and “cost cutting. “

Lean is  not an acronym (“LEAN”).

Lean is NOT…

• NOT just a few tools to use
• NOT a group of best practices to copy
• NOT just a bunch of projects to conduct
• NOT experts telling you what to do
• NOT a way to drive layoffs
• NOT just a process improvement methodology
• NOT just for frontline staff
• NOT “part of Six Sigma”
• NOT just about speed & efficiency
• NOT pressuring people to hit certain metrics
• NOT a silver bullet or an easy transformation

Lean is…

“ Lean ” is the set of management practices based on the Toyota Production System (TPS). The phrase “Lean Production” was coined by a group of MIT researchers who wrote the book The Machine That Changed the World .

Lean Production is basically the same thing as:

• Lean Manufacturing
• Lean Enterprise
• Lean Thinking
• Lean Healthcare
• Lean Government
• Lean Startups

It's the same principles and mindsets, applied for different purposes given the industry.

Lean has been applied in manufacturing (factories, product design, and administrative functions) as well as service industries (including healthcare, banking, and government). The U.S. Army has an active “lean six sigma” program underway as of 2011.

See my article on LinkedIn: 

“Lean” is Not Just for Manufacturing – It Applies to Knowledge Work of All Types, Too

The Toyota Production System , a.k.a. Lean is defined as having two primary pillars:

• Just-in-Time (improving flow)
• Quality at the source

Jamie Bonini, the President of TSSC , defines TPS as:

 “We define TPS as an organizational culture of highly engaged people solving problems or innovating to drive performance.” 

Jamie also describes TPS as mainly a philosophy , as described in this post:

Lean: The Toyota Production System is Mainly About the Philosophy

The Toyota Europe website has a page that describes the philosophy as they see it, and this page decribes the Toyota Way 2020 .

Another way of defining Lean (“ The Toyota Way ” management system) has two parts:

• Eliminate waste and non-value-added activity (NVA) through continuous improvement
• Practice respect for people

The opposite of waste is value-added activity, which has a special Lean definition. An activity is “value added” if, and only if, these three conditions are met:

• The customer must be willing to pay for the activity
• The activity must change the “form, fit, or function” of the product, making it closer to the end product that the customer wants and will pay for (in healthcare, this can mean moving the care process forward, such as comfort, diagnosis, treatment, education, prevention)
• The activity must be done right the first time.

We aren't just reducing waste, we're also trying to provide the most value to customers through Lean methods.

In healthcare, I generally think of “value” in a patient care process to be the work that involves things like:

• Comforting the patient
• Examining them
• Diagnosing them
• Treating them
• Educating them
• Preventing future illness

Respect and Leadership

“ Respect for people ” is much more complex to define than it might seem.  Lean isn't about “being nice” and smiling all of the time. Respect means you challenge people to do their best because you believe in them and it also means that you collaborate and work together with them in improvement (the practice of “ kaizen “).

See this article about “respect for people in healthcare ,” as well.

Lean leadership is about enabling and empowering people. Lean leadership is about helping people grow professionally and personally, allowing them to take pride in their work. Lean leadership recognizes how a system operates. Lean leadership doesn't set targets for people, go back to their office, and then yell at people when they don't hit those targets. Lean leaders spend time coaching people. They spend very little time in their office. They lead people and see what is actually happening rather than managing metrics and reading reports.

Much of the “people side” of lean was adapted from the teachings of the American professor and consultant   W. Edwards Deming , who taught Toyota and other Japanese companies after World War II. Lean was also adapted from Toyota's study of the early practices of Henry Ford and the Ford Motor Company. Note the emphasis on “early.” Lean is not strictly a Japanese invention nor is its use limited to Japan or Japanese companies.

Lean Resources, Reading, and Listening

If you're new to Lean, welcome. I hope you'll enjoy learning more about it.

Also, check out the Lean Enterprise Institute and their   “What is Lean?” pages.

Toyota's corporate website has a nice set of TPS pages . As does Toyota Europe .

I also invite you to check out  my series of Lean Blog Interviews Podcast episodes, which include interviews with leading Lean thinkers, writers, and leaders.

• Lean isn't about “Quality” and “Productivity”
• My Thoughts on Standardized work
• Common Sense on Offshoring and Lean
• Putting the “Continuous” Back into Continuous Improvement

This page is going to grow and evolve over time. It is hard to write a succinct definition of Lean that captures all of its principles and philosophies (but here's a post where we all tried ).

Lean process improvement: What is it and how to apply it to projects

Browse topics.

Continuous improvement is a fundamental principle of Lean methodology , and Lean process improvement focuses on eliminating wasteful activities to streamline a company’s processes. It involves analyzing and assessing projects while they are underway and after completion to identify opportunities for improvement. This method seeks to create a systematic approach to allow teams to deliver more customer value via the continuous improvement cycle.

This article breaks down the Lean process improvement methodology and compares it with other software development methodologies, such as Agile and DevOps principles.

What is Lean process improvement?

Lean process improvement focuses on eliminating waste from processes so that the team only works on tasks that create customer value. It’s a cycle of continuous improvement that ensures a team stays Lean.

This isn’t a one-and-done approach. Doing this practice correctly will help sustain momentum and keep projects moving forward. The key objective is to create a systematic means of delivering customer value faster. It’s a long-term practice that works best if the entire company adopts it.

Benefits of Lean process improvement

Lean process improvement ensures teams are only working on tasks that will deliver value to customers, saving the company resources and money.

Lean process improvement has the following benefits: 

Increased efficiency : Analyzing and improving your process allows you to better estimate future sprints’ deadlines and deliverables. 

Better collaboration : Continual improvement fosters cross-collaboration company-wide. It encourages teams to communicate issues or opportunities for process improvement. 

Improved morale : Streamlined and stable processes create more wins for a team, improving morale. 

Decreased waste : Teams only work on essential tasks, decreasing time wastage.

Growth mindset : Lean management encourages everyone to continually seek improvement. 

Satisfied customers : If a company consistently delivers value, customers become advocates for its products. 

Ability to remain relevant : The ability to shift priorities and adapt prevents stagnation.

How to apply Lean process improvement within projects

Using Lean principles to improve processes is a process in itself. Here’s how to integrate it within a company in four easy steps:

1. Determine potential areas for improvement

Gather your team and take an honest look at your current processes. Identify areas where the processes are not meeting your team’s needs and could benefit from change. 

For instance, you might have an ongoing blocker each time you move from design to development. Investigate what is causing that blocker. Is it miscommunication? Are there skill gaps? Does the design team need more support? 

Consider visualizing your workflow with a Kanban board . A root cause analysis template can also guide you through this process. 

2. Identify potential solutions

Once you pinpoint improvement areas, involve the team in finding potential solutions. Their experience often allows them to generate effective solutions. Challenge traditional ways of doing things and seek to break the “how we’ve always done it” mindset. 

From these potential solutions, determine which ones are most feasible. Then, choose a focus area and develop an action plan to implement the ideas. 

3. Implement improvements

Implementing change can be challenging. There may be initial resistance. However, proper planning and project collaboration make this process easier and help teams work together.

Using a project plan template ensures cross-functional collaboration because it outlines the plan of attack and helps determine the best way to implement solutions. You can map out the project’s logistics beforehand so everything is crystal clear. Having a plan also ensures the involvement and collaboration of stakeholders, as they’ll be able to track and monitor progress.

4. Monitor outcomes

Implementing solutions is not the end of the process. It is crucial to monitor performance and gather data to determine if the solutions resulted in improvements. It is also essential to identify the reasons behind the success or failure of the solutions. 

Analyzing this data can reveal areas that require further refinement. This is normal, as the process is cyclical; the goal is to continue to improve and refine the solutions.

Now that we’ve looked at how to implement this methodology, let’s see how it compares with other methods.

Lean process improvement vs. value stream management

Value stream management (VSM) is another Lean methodology focused on improvement. It aims to improve how teams deliver high-quality customer experiences by focusing on the speed at which customers receive updates and whether they value the changes.

VSM examines a company’s overall product development and delivery system. It seeks to enhance the end-to-end process of delivering the product, service, or experience. Lean process management, however, is task-oriented and focuses on specific processes.

Teams can rely on  Jira to streamline workflows and processes and scale their team collaboration. Jira Align helps companies visualize value streams across teams, set up process flow automation, and align work with business needs.

Lean process improvement vs. Agile

Agile project management , another Lean methodology, is an iterative process for software development with continuous releases based on customer feedback.

Agile has four key values and 12 guiding principles, which put people over processes and tools. They strive to improve communication within teams and between customers.   

Like VSM, Agile project management aims for overall process improvement. It achieves this through ongoing communication between end-users and the development team.

Scrum and Kanban are two Agile frameworks. Scrum is designed for teams that deliver work on a regular cadence or work in short, time boxed periods called sprints. Kanban, however, is designed for teams that limit work-in-progress and focus on a continuous flow of work. Jira supports both agile methodologies, making it easier for software teams to organize work, stay aligned, and build better products.

Lean process improvement vs. DevOps

DevOps refers to a cross-functional team of operations and developers who communicate, share feedback, and collaborate throughout the development process. DevOps principles focus on increasing the speed of software development through cross-functional collaboration. It breaks the walls between the development team and the operations team. DevOps uses a customer-centric method to make process improvements using feedback loops with end-users. Lean process management relies on the internal team rather than the customer.  

Open DevOps , powered by Jira, can help software teams implement this methodology and keep them focused on delivering value to customers. It integrates easily with Atlassian and partner tools so teams can focus on building and operating software.

Can you apply all of these principles at once?

Yes, these four Lean methodologies build upon each other, allowing a company to improve its processes and productivity. Lean process improvement can refine internal processes and eliminate wasteful activities. VSM can hone the customer value stream, delivering better quality products. Agile keeps teams nimble and responsive to change. And DevOps increases team empathy for customers. 

The outcomes of these methodologies result in improved customer experience and satisfaction

Jira for Lean process improvement

Jira simplifies the complexities of software development, supports teams at every stage of the delivery lifecycle, and enables teams to stay lean. Contextual insights empower teams to build and train muscles to continuously learn and improve their way of working. Scrum and Kanban boards give your team full visibility into what’s next so you can continuously deliver maximum output in minimal time. With Jira as the backbone of collaboration, all teams can stay in lockstep with each other and the rest of the organization.

Jira can also help large organizations visualize value streams across teams. You can further automate your process flows and ensure work aligns with strategic business objectives. All of this will help you stay lean as you track investments, streamline operations, and uncover roadblocks. That way, your team will deliver continuous value to customers.

Lean process improvement: Frequently asked questions

What are the 5 lean principles.

The five Lean principles are the cornerstone of the Lean process. They originated in Japan’s automotive industry and are used in various industries. Let’s break them down: 

Define value : Determine which activities provide customer value. 

Map the value stream : Visualize customer value activities to keep projects on task. 

Create flow : Remove any roadblocks before they interrupt the team’s flow. 

Establish a pull system : Produce according to actual demand rather than forecasted demand. 

Seek continuous improvement : Look for opportunities to improve processes and find efficiencies.

What are the most common Lean process improvement techniques?

Here are a few common techniques to improve processes using Lean principles: 

Kanban : This technique uses cards to organize and visualize team activities. It allows the entire team to see what’s moved from “to-do” to “done.”  

5 Whys : Asking why five times helps identify the root cause of a problem. It allows you to constantly drill down on an issue until you get to its initial cause.  

WIP Limits : In this technique, the project manager sets the limit of work that can exist in any given workflow. Having WIP limits prevents the team from getting overloaded and stressed.

What are the most important things to keep in mind when using a Lean process improvement approach?

To achieve continuous improvement, a team must strive to reduce and eliminate waste as an ongoing practice. It’s not a one-and-done approach; it’s a cyclical process of improvement. Best practices also recommend focusing on a singular process issue at a time rather than tackling them all at once. It’s easier to solve one issue at a time than to spread out your efforts and try to address all the problems at the same time.

Lean Management Definition

Lean management is a systematic approach to optimizing efficiency by minimizing waste and maximizing value for the customer. Originating from the Toyota Production System (TPS), it is characterized by a relentless pursuit of improvement and a focus on value creation through waste elimination.

The main goal of Lean management is to improve efficiency and effectiveness by reducing the time spent on non-value-adding activities and optimizing the flow of work. Such waste in Lean can include overproduction, waiting time, unnecessary transportation, excess inventory, unnecessary processing, and defects.    The Lean concept is successfully applied to any business or production process, from manufacturing to healthcare, engineering, and software development. 

The Birth of Lean Management

Lean management has its roots in the  Toyota Production System , which was established in the late 1940s.   In the late 1940s, when Toyota put the foundations of Lean manufacturing , they aimed to reduce processes that don’t bring value to the product. By doing so, they succeeded in achieving significant improvements in productivity, efficiency, cycle time, and cost efficiency.    The success of the TPS at Toyota led to the spread of Lean thinking and the implementation of Lean principles around the world. Today, Lean management is used in a wide range of industries and organizations and has evolved to include a variety of tools, techniques, and approaches.  

Indeed, the term "lean production" was made up by John Krafcik (former CEO of Google’s self-driving car project Waymo) in his 1988 article "Triumph of the Lean Production System". His studies formed the data behind James P. Womack’s 1990 book "The Machine That Changed the World: The Story of Lean Production". 

What Are the 5 Lean Management Principles?

Five Lean principles

1. Identify Value

What does every company strive to do? To offer a product or service that a customer is ready to pay for. To do so, a company needs to add value defined by its customers’ needs.

The value lies in the problem you are trying to solve for the customer. More specifically, in the part of the solution that your customer is actively willing to pay. Any other activity or process that doesn’t add value to the product is considered a waste.

In Lean, value is the first thing you need to identify. So, first, decide what you want to deliver, then move on to the next step.

2. Value Stream Mapping

This is the point where you need to map your company's workflow. It should include all actions and people involved in delivering the product to the customer. By doing so, you will be able to identify which parts of the process bring no value.

Applying the Lean principle of value stream mapping will show you where value is being generated and in what proportion different parts of the process do or do not produce value.

When you have your value stream mapped, it will be much easier for you to see which processes are owned by which teams and who is responsible for measuring, evaluating, and improving those processes. This big picture will enable you to detect the steps that don’t bring value and eliminate them.

3. Create a Continuous Workflow

After you master your value stream, you need to ensure that each team's workflow remains smooth. Keep in mind that it may take a while.

Developing a product or service will often include cross-functional teamwork. Bottlenecks and interruptions may appear at any time. However, by breaking down work into smaller batches and visualizing the workflow, you can easily detect and remove process roadblocks.

4. Create a Pull System

Implementing a pull system guarantees a stable flow of work and enables teams to complete tasks more swiftly and easily. As a lean strategy, a pull system reduces waste in the production cycle by initiating new tasks only when there is a clear demand. This lets you optimize resources’ capacity and deliver products or services only if there is an actual need.

Let’s take a restaurant, for example. You go there and order a pizza. The baker pulls your order and starts making your pizza. He doesn’t prepare tons of dishes in advance because there isn’t actual demand, and these tons of dishes can turn into a waste of resources.

5. Continuous Improvement

After going through all the previous steps, you have already built your Lean management system. However, don’t forget to pay attention to this last step, probably the most important one.

Remember, your system is not isolated and static. Problems may occur with any of the previous steps. This is why you need to make sure that employees on every level are involved in continuously improving the process.

There are different techniques to encourage continuous improvement. For example, every team may have a daily stand-up meeting to discuss what has been done, what needs to be done, and possible obstacles - an easy way to process improvements daily.

What Are the Benefits of Lean Management?

Lean management can help organizations and teams alike to create a stable work system with a higher chance of improving overall performance. Here's a list of the major advantages you can benefit from when introducing Lean.

Increased employee engagement and focus : Lean encourages employees to identify and solve problems leading to increased engagement and focus on activities that bring value.

Improving productivity and efficiency : By eliminating waste and streamlining processes, Lean management can help organizations become more efficient and productive, allowing them to produce more with the same or fewer resources.

Faster time to market : By establishing a pull system, a Lean management system helps organizations deliver work only if there is actual demand and reduces their lead times.

Improved quality : Lean management places a strong emphasis on identifying and eliminating defects, which can help to improve product and service quality.

Continuous improvement : Lean management is built on a culture of continuous improvement, enabling organizations to adapt to changing market conditions and stay competitive over the long term.

Common Challenges When Implementing Lean Management 

While Lean management has many benefits, it is important to also consider the potential disadvantages, which can include:

Resistance to change : Implementing a lean management system can be a significant change for an organization and may be met with resistance from employees who are used to more traditional ways of working.

Difficulties in implementation : Implementing a lean management system can be complex and challenging, requiring significant investment in training, infrastructure, and culture change.

Risk of over-focusing on data : Lean management relies heavily on data and metrics to measure performance, which can lead to a focus on short-term results at the expense of long-term goals or strategic planning. 

Lean Management Examples 

Lean software development .

In 2003, Mary and Tom Poppendieck published their book "Lean software development: an Agile Toolkit". The book describes how you can apply the initial principles of the Lean methodology to software development. 

At the end of the day, Lean software development comes down to 7 principles. In the beginning, it didn’t gain popularity, but a few years later, it became one of the most popular software development methods.

The Lean Startup

Eric Ries, an engineer and serial entrepreneur, developed a methodology based on the Lean principles to help startups succeed. In 2011, he packed his ideas into a book called "The Lean Startup". The concept consists of 5 basic principles that aim to help startups be more flexible and responsive to changes.

From a business point of view, Lean is to shorten product development cycles and rapidly discover if a given business concept is viable. This methodology is also employed by government structures, marketing professionals, and others.

Lean Accounting

Lean accounting refers to the application of Lean management principles, such as a focus on delivering value to the customer and waste reduction to managing financial practices and processes. The approach allows organizations to streamline their operations and align them with the strategic goals of the organization.

Furthermore, by promoting Lean thinking in accounting, companies can make financial information easier to understand and more relevant across an organization’s teams and departments.

Lean Management Applied in Healthcare

Lean management principles find an increasing application in healthcare institutions to improve patient care, service quality, healthcare workers’ satisfaction, and cost-effectiveness.

What Are the Different Tools of Lean Management?

Some of the most common lean tools  and techniques used by organizations and teams new to the Lean philosophy include:

• Value-Stream Mapping (VSM):  for visualization, analysis, and improvement of all the steps in a product or service delivery process.
• 5 Whys Root Cause Analysis : for uncovering the root cause of process bottlenecks and constraints.
• Kanban : for defining, managing, and improving services that deliver knowledge work.
• 5S Method : for workspace optimization to reduce waste and streamline processes.
• Gemba Walk : the main idea of the Gemba walk is for managers and leaders on every level to take regular walks around the shop floor and be involved in finding wasteful activities.
• Andon : a system developed to alert operators about an issue on the production line in lean manufacturing.
• Continuous Flow : allows you to move a single product through every step of your process instead of grouping work items into batches.
• Heijunka : reduce unevenness and minimize the risk of overburdening in processes.
• Hoshin Kanri : a 7-step planning process used to communicate strategic goals across the company.

Lean methodology 101

Reading time: about 7 min

Let’s say your company leads the market within your industry. You could easily just keep doing what you’ve been doing. Evidently, it’s worked well for you—if it’s not broken, don’t fix it, right? This approach can work for a while, but you risk becoming complacent.

History is full of companies that became complacent after reaching success. And complacency eventually led to a lack of innovation, failure to embrace new technology, and the inability to adapt to changing market trends. When a company becomes stagnant, it risks losing everything as customers look for other ways to meet their needs.

Successful companies understand that change and improvement are essential for business growth and market share. In this article, we’ll discuss how the Lean methodology can help you to improve productivity, eliminate waste, and keep your customers happy.

What is Lean methodology?

The Lean methodology, also known as Lean manufacturing, Lean thinking, or Lean management, is used to maximize value and quality while minimizing waste. 

Lean focuses on customer centricity, meaning the customer is at the center of everything you do. Customer needs and wants drive decision-making, development, processes, and operations to ensure a positive customer experience.

The success of TPS captured global attention from companies wanting to learn how they could continually improve, boost efficiency, and produce high-quality goods while eliminating waste. 

TPS formed the foundation of Lean methodology. Researchers James P. Womack and Daniel T. Jones introduced Lean in the early 1990s in their book The Machine That Changed the World , which helped popularize Lean principles outside of Japan.

While the Lean methodology was originally developed for optimizing efficiencies in manufacturing, it has been applied to other industries such as healthcare, software development, hospitality, construction, and beyond.

Pillars of Lean 

Lean methodology includes several principles, also called the pillars of Lean, that organizations use to guide the implementation of Lean practices.

Because Lean principles focus on the customer, you must define what is valuable to your customers. This means identifying the features, attributes, and outcomes the customers are willing to pay for. Don’t include “cool to have” features or functionality if your customers don’t need or want them. By identifying what is of value to the customer, you eliminate the waste of time and resources on things that don’t matter.

Use our free value proposition template to ensure that the products you develop or manufacture will meet your customers' needs.

Value stream mapping

A value stream is the sequence of processes, steps, and activities involved in developing and delivering products and services of value to your customers.

A value stream map lets you visualize the value stream. This involves identifying and categorizing the flow of all the information, materials, and processes that turn your inputs into products or services. 

This free value stream map template can help you visualize and analyze the events that must happen throughout a project until the product is delivered to the customer.

The aim of this pillar is to create a smooth workflow that won’t be interrupted by bottlenecks or  disruptions. Creating a process workflow chart can help you identify areas that could cause problems and impede your workflow. Identifying problem areas early on makes finding solutions easier so the work continues as expected.

A workflow chart can also help you analyze how well current processes work so you can continuously look for ways to improve them.

Pull systems

In a pull system, work is aligned with customer demand. Work is completed based on actual demand instead of anticipated demand. This minimizes waste by ensuring that resources are only used when needed, limiting overproduction.

Continuous improvement

This pillar emphasizes creating a culture of continuous improvement . Employees at all levels are encouraged to analyze current processes, identify improvement areas, and implement small incremental changes to increase efficiency. This will help you to improve quality and deliver increased value to your customers while you reduce waste, inconsistencies, and possible defects.

Respect for people

Companies need to value and respect their employees. Involving your employees in the company’s improvement efforts empowers them to share knowledge and skill. When employees feel their contributions are important, it gives them a sense of ownership in developing your products and services. That sense of ownership encourages collaboration and teamwork, builds trust, and establishes a supportive work environment, which can also help in employee retention efforts.

Visual management

Use visual collaboration tools like Lucidchart to make your projects more visible and transparent. Displaying charts, schedules, boards, and diagrams in a prominent space gives employees an overview of the project’s current state. Understanding what work has been done, what is being done, and what still needs to be done keeps everyone on the same page.

A visual representation of your processes and workflows also makes it easier to find potential problem areas so you can fix them before they cause delays.

Standardization

Developing and implementing standard processes helps you establish best practices, so your work and delivery methods are consistent. Once you identify deviations and roadblocks, you can quickly develop and implement improvements with little to no downtime.  

Lean in software development

The concepts in the Lean methodology originally applied to manufacturing, but software development was one of the next industries to adopt it.

In the context of software development, Lean is the same as it is in manufacturing. The focus is on efficiently and effectively adding value to software applications that meet customer needs. 

Lean lets software development teams improve efficiency, reduce costs, eliminate waste, standardize processes, increase productivity, and maximize customer satisfaction. When combined with Agile methodologies like Scrum, Lean lets teams quickly respond and adapt to changing customer requirements by adding value incrementally in short iterative cycles. 

There are several tools you can use to help you implement Lean practices in your workplace. These tools are designed to help you:

• Focus on customer-centric product development
• Identify and eliminate waste
• Boost efficiency
• Increase the overall value of your products

We have hundreds of templates to get you started. Here are a few to consider.

Affinity diagram

An affinity diagram helps you gather and sort data to consolidate similar ideas and information. From there, you can analyze the data and prioritize the best ideas and solutions to address customer concerns and meet their expectations.  

Kanban board

The Japanese word “kanban” means sign or billboard. A Kanban board is a visual management tool that divides your work into three columns: items you need to do, items you’re working on, and completed items. 

As new tasks or work items are added to a project, they are written on a card and placed in the “To do” column. When a team member chooses an item to work on, its card is moved to the “Working on” column. The card is moved to the “Finished” column after completing the work item.

Kanban boards help you manage your workload balance, track progress, and identify potential bottlenecks or disruptions.

5S dashboard

This tool is used to help you organize your workspace to maximize efficiency. The 5S dashboard includes the following sections:

• Sort : Identify unnecessary items in your workspace and remove them.
• Set in order : Arrange the necessary items where they are most easily accessible for their function.
• Shine : Clean your workspace and tools regularly.
• Standardize : Establish consistent and repeatable processes and procedures to maintain the first three practices.
• Sustain : Create a culture where employees consistently follow and adhere to the 5S principles.

What Is Lean?

Management guru Peter Drucker said, “There’s nothing so useless as doing efficiently that which should not be done at all.” Lean is an improvement and problem solving methodology that strives to reduce or eliminate activities that don’t add value to the customer.

Lean is founded on two pillars: respect for people and continuous improvement. According to Dr. Shigeo Shingo, a Toyota engineer and expert on the methodology, Lean is a never-ending elimination of waste; it is committed to total customer satisfaction, total commitment to quality and total employee involvement.

An industrial engineer at Toyota, Taiichi Ohno, first developed the Lean methodology in the 1950s, then known as the Toyota Production System. One of the system’s major innovations is that workers were seen as problem solvers who are trained and empowered to improve their processes and eliminate waste.

Since the 1950s, the Lean methodology has made great strides in improving business performance across both manufacturing and transactional environments.

The Five Principles of Lean

Lean is much more than just a set of problem-solving tools. It was based on a foundation of principles designed to not only quantify and eliminate waste, but also help companies change the way they do business for the better. The following are five foundational principles of Lean and how they work together.

• Value —Understanding what the customer is willing to pay for. Value is always defined by the customer and is categorized in three ways: non-value add activity (waste), value add activity, and business value add activity.
• Value stream mapping —Mapping the process, steps, or sequence that a product or service goes through in a company.
• Flow —Allowing product and information requests to flow smoothly through the business without delay or disruption.
• Pull —Replacing only material that is used and eliminating excessive inventory, which allows us to respond quickly to customer requirements.
• Strive for perfection —Always striving to eliminate waste and improve the value provided to customers.

Understanding Value

In Lean terms, value is always defined by the customer, and there are three ways to categorize value: 1) Non-value add activity, known as waste, or muda in Japanese. 2) Value-add activities, which are essential, and 3) business non-value add activities, which are things that must be completed but don’t add value to the customer, such as meeting regulatory requirements.

To help determine if a process is value-add, Lean experts have developed a simple flowchart of questions. If the answer to all three of these questions is “yes,” then the process or process steps are value-add.

• Is the customer willing to pay for the good or the service?
• Does the step transform the good or service?
• Is the action done for the first time, or is it done many times?

Eliminating Waste

A key tenet of Lean is the reduction of waste. Using the acronym WORMPIIT, here’s a look at the eight types of waste that can be eliminated by using Lean techniques.

Roles and Responsibilities

Within a Lean program, there are a handful of important roles. Here’s an overview of those roles and the responsibility and associated training of each.

Lean Masters

Lean Masters are expert leaders of Lean efforts, driving the organization toward the future state. They work with the core team and champions to manage Lean efforts, including developing training material, instructing Lean Leaders and practitioners, and mentoring projects. Lean Masters also help manage the project pipeline and lead larger scoped projects. Not only are Lean Masters very knowledgeable on methodology and application, they’re also seen as leaders in their organization and gain exposure across the company. Training: Lean Master Development Program

Lean Leaders

Lean Leaders, also known as Lean Facilitators, are skilled practitioners of the Lean methodology. They are ideally dedicated full-time to leading SCORE events and other improvement projects. Executing four to six projects a year, Lean Leaders are experts in applying Lean tools and principles to reduce waste, improve processes, gain efficiency and boost productivity.  Additionally, Lean Leader certification is seen as a personal and professional development building block that prepares people for leadership roles later on. Training: Students should start with the Lean Practitioner course and progress through advanced Lean courses – please inquire

Lean Practitioners

These part-time resources carry the language of Lean deeper into the organization. They support and sometimes lead smaller scale projects, and also assist Lean Leaders and Lean Masters with team activities and tool application. Lean Practitioners become local advocates for continuous improvement and problem solving, and accelerate number of employees positively affected by Lean. Training: Lean Practitioner Certification course

Process Owners and Team Members

Process Owners and Team Members assist with projects and tool application, as well as the implementation and continued control of improvements. They are also involved with culture change at a local level, as well as with project identification and execution. Training:   Lean Concepts and Tools Online

Certified Scrum Master – Agile

Scrum Masters facilitate a team that is using the Scrum approach to agile development. Originating in the IT world, this course is designed for any role at any organization. Scrum Masters are responsible for ensuring communication flows between the product owner and delivery team and for removing roadblocks and setting up processes for smooth workflow. When working with Agile, Scrum Masters also apply Lean tools and principles to remove waste from the development processes and requirements. Training: Certified Scrum Master

The SCORE Roadmap for Kaizen Events

Sometimes known as “rapid improvement,” kaizen means “change for the better” in Japanese. Its essence is that change is good and good change is better. By this definition, anything a company does to make itself stronger is a Kaizen, and anyone who leads a Kaizen event in a company is a force for good change.

Change is good and good change is better.

Kaizen is a component of Lean that is designed to break down the project mentality of an organization and create a bias toward action. A Kaizen event is planned and structured and enables a group of associates to improve some aspect of their business quickly.

SCORE is a five-step methodology that provides the framework for managing and executing successful Kaizen events. Its five phases run in sequence and feed each other.

Learn more about SCORE in this article on “Leading Lean Kaizen Improvements.”

Complementary Methods

While some companies deploy Lean solo, more often than not it is part of broader continuous improvement or performance excellence efforts that include Six Sigma, innovation, and other problem solving approaches.

Lean is often applied in conjunction with Six Sigma. Lean focuses on reducing waste so what is left is value-added. Six Sigma focuses on reducing variation and defects. Together, the two become a powerful combo to first lean out and then perfect your processes. In the last decade, companies have moved from treating Lean and Six Sigma as independent approaches to combining them into an improved operating system.

All of these continuous improvement efforts roll up into the organization’s strategic planning and execution, ensuring that everyone is working on improvements and innovations that align with the company’s strategic goals.

What is lean project management? 5 principles explained

Lean project management is an Agile methodology that increases customer value by eliminating waste from each project phase. In this piece, we’ll explain what lean project management is and outline how to use it to improve your productivity.

When you adopt the lean approach, your goal is to reduce waste and add value during every project phase. In this piece, we’ll explain what lean project management is and outline how to use this Agile methodology to improve your productivity . 

How was the lean project management methodology created?

Japanese engineers at Toyota invented the Toyota Production System (TPS) between 1948 and 1975, which served as the inspiration for what we know as the lean methodology today. The TPS was used to improve manufacturing and enhance interactions with suppliers and customers, as well as eliminate waste. 

Dr. Jeffrey K. Liker, author of “The Toyota Way,” outlines the principles of lean management in his book and explains how companies can apply the TPS to other industries. Liker also explains how TPS—and lean management as a whole—can eliminate various types of corporate waste. 

John Krafcik was the one to introduce the lean approach to project management in his 1988 article titled, “ Triumph of the Lean Production System .” Krafcik wrote this article for his master’s thesis at MIT Sloan School of Management, and his research resulted in the best-selling book,  “ The Machine That Changed the World.” Lean project management has influenced a whole subset of methodologies, including Agile, Kanban, and Scrum.

5 principles of lean project management

The five principles of lean project management serve as steps for how to reach prime customer satisfaction. Use these steps if you want the best chance of reducing product waste, staying within project scope , and meeting critical success factors .

1. Identify value

The first core principle in the lean project management process is to identify your product value. To do this, you need to know your stakeholder. Sometimes you’ll be creating project deliverables for internal stakeholders , while other times you’ll have a customer who’s an external stakeholder.

An internal stakeholder is a shareholder of the project who monitors a product’s development because they have a stake in its success.

An external stakeholder is a customer who buys the product or service and is affected by its quality.

Once you know who you’re building your product for, you can better determine how to make it valuable. For example, product value for an internal stakeholder may mean meeting an internal operations need. Product value to a customer may mean solving a customer problem or making the customer’s life easier. 

2. Map the value stream

Value stream mapping (VSM) is the next principle in lean project management. VSM is a visual tool that involves diagramming your current workflow and your ideal workflow from project initiation to completion. 

When comparing the two workflows, you can identify waste across each project management phase to maximize efficiency. 

Toyota identified types of waste you may find through VSM in lean manufacturing, but in parentheses, you can see how these items may translate to other industries:

Overproduction (Unnecessary features): Overproduction and unnecessary software features can lead to added costs like extra storage, wasted materials, and useless inventory.

Inventory (Mismanaged backlog): Inventory waste, waste from incomplete work, and mismanaged backlogs all incur unnecessary costs for storing inventory, transportation costs, and additional costs spent to complete work.

Motion (Task switching): Motion waste is the unnecessary cost of internal motion by people or machines. This can take the form of redundant processes or an overabundance of business apps. In fact, the average knowledge worker switches between 10 apps up to 25 times per day, but 27% of workers say that actions and messages are missed when switching apps.

Defects (Technical debt): Defects can result in costly repairs and a loss of materials. Technical debt can result in a loss of valuable time.

Over-processing (Expensive tools): Over-processing can lead to unnecessary costs like upgrading a product that users didn’t ask for or don’t need. Similarly, money spent on expensive tools can be a waste if the tools aren’t worth it.

Waiting: Waiting waste is the cost resulting from delayed timelines in final product deliverables.

Transport: Transport waste is similar to motion waste and deals with external movement, like the unnecessary movement of product and materials. 

Fragmented teams: Fragmented teams can result in wasted costs due to miscommunication, unnecessary meetings, and lack of strong collaboration.

VSM is the most important step in lean project management. Without it, you won’t have the visualization you need to notice flaws in your project life cycle and improve product quality for customers. 

3. Create flow

In this step, you’ll rework your project management plan to be more efficient by removing the waste you identified in step two. To do this, break down every stage of product development and reconfigure steps as needed. Use project milestones as checkpoints to ensure new waste doesn’t develop as the project progresses. 

For example, imagine you identified in step two that you have a mismanaged backlog and delayed timeline due to a bottleneck in team member scheduling. This is where you’ll determine how to remove those pain points and piece your project plan back together. 

Establishing open communication with your team members is the best way to ensure your VSM was worth the effort. Once you’ve taken time to identify and remove waste, your team can work together to prevent future inefficiencies and keep waste from building back up. 

4. Establish pull

Establishing pull means pulling work from the previous process stage as work is completed. This concept originated in manufacturing to help factories meet the exact demands of their customers with a “just-in-time” inventory system. However, a pull system is also helpful in other industries because it keeps your workflow moving efficiently. 

Example of a pull system in software development:

The tech designer finishes their task and flags the product for review.

The review flag signals the coding stage to begin.

Your coder finishes their task and flags the product for review.

The review flag signals the testing stage to begin.

The product tester finishes their task and flags the product ready for final review.

You conduct a final review of the product.

Establishing pull can help teams in various industries because it keeps work moving seamlessly through the project life cycle. Industries that produce customer-facing products will benefit from this system if they use pull signals to work backwards. That way, their team only produces inventory when customers need it. 

5. Continuous improvement

Lean project management isn’t a one-time thing—rather, it’s an iterative process . Striving for perfection is the fifth principle, which involves making continuous improvements to your workflow. 

Whether your customer is an internal or external stakeholder, their demands will be ever changing. This means you’ll need to assess your product value intermittently and regularly analyze your workflow for waste.

Lean project management tools

You can use the tools below to improve your product development workflow. When striving for continuous improvement, these tools will help you and your team reduce waste, improve productivity, and increase customer value. 

Deming cycle (PDCA)

Dr. W. Edwards Deming developed the Deming Cycle in the 1950s. His method, also known as the Plan-Do-Check-Act cycle, or PDCA, was a revision of an earlier three-step problem-solving method created in the 1920s by Dr. Walter Shewhart. 

There are four steps in the PDCA cycle :

Plan: Investigate your workflow and identify any problems that need solving.

Do: Find solutions to the problem by analyzing data or collaborating with team members. 

Check: Monitor whether your solutions are effective and make improvements to your plan if needed.

Act: Apply revised solutions and assess what you’ve learned.

The Deming cycle is a simple process you can apply to various organizational processes. When implemented correctly, this process can make a significant impact on your product value. 

Lean Six Sigma project management (DMEDI)

Lean Six Sigma is a lean management tool you can use to identify problems in your workflow. This tool has steps just like the Deming cycle, but it also has methods of analysis you can use alongside it. The Lean Six Sigma steps, also known as DMEDI, are as follows:

Define: Define your project scope and plan goals

Measure: Determine how you will measure success in your project

Explore: Explore new ways to improve the project process

Develop: Develop a fool-proof project plan

Implement: Implement the project plan

The methods of analysis you can use with Lean Six Sigma include:

Value stream mapping: As mentioned above, VSM can help you visualize the phases of your project management plan and identify areas of waste.

Customer feedback surveys: Getting feedback from customers is a great way to assess project issues and increase product value.

Gantt charts: Gantt charts are like bar graphs that can help you visualize project milestones.

Root cause analysis (RCA): Use RCA to discover the root causes of problems and find solutions.

Kanban: By visualizing your tasks and limiting work in progress, Kanban boards help you see how your work flows. 

You can decide which lean management method to try based on your industry, your product, and your team. You can also try various lean management methods on different project initiatives and see which works best. Regardless of which method you implement, make sure you’re using project management software to easily implement these methods of analysis. 

Why lean management is important

Industries like IT, construction, and education have adopted the lean methodology because of the many benefits it provides. Lean project management can improve product value by streamlining processes. 

Other benefits of lean management include:

Increased innovation: Improves the project by sparking creativity

Reduced waste: Reduces physical waste and waiting times between production steps, while also minimizing overproduction and over-processing

Enhanced customer service: Provides what the customer needs—nothing more, nothing less

Better lead times: Results in faster response times and fewer delays

Higher quality products: Minimizes product defects by adding quality checks

Improved inventory management: Prevents setbacks by monitoring inventory

Whether your company serves internal or external stakeholders, switching to lean thinking can simplify your work processes and create a more efficient project team. 

Improve your workflow with lean project management

Many companies work hard to produce high-quality products and leave their customers satisfied, but the lean methodology makes achieving these goals easier by removing bottlenecks and cleaning up production.

Regardless of which project management system you use, project management software can aid in process improvements. When you use software to streamline your processes, you can better visualize your project schedule , communicate with team members, and meet customer requirements.

What Is Lean Management? Principles & Everything You Need to Know

• Written by Contributing Writer
• Updated on February 26, 2024

You may have heard of lean management a few times in business school or the workforce. Companies have been using lean management principles for a long time and continue to perfect the lean management methodology. However, you may not know precisely what it is if you have yet to study it directly or are in a company that uses lean management throughout its operations.

Altogether, lean management is simple when it comes to business management methodologies. Once you know the underlying principles, you’ll see how easy it can be to implement them in any business.

Here is what you need to know about the lean project management methodology and how to earn a Lean Six Sigma certification to boost your career.

What Is Lean Management?

Lean management is a business running method where stakeholders try to remove any task or process that does not create value. By removing this waste from the company’s operations, the company sees improved productivity, cost management, and quality control. In many cases, it can also mean higher job satisfaction for workers.

Companies adopt lean project management principles because it allows them to optimize the company for success. Less waste often leads to wider profit margins, which make a company more successful in good times and more resilient in hard times.

The History of Lean Management

The idea of lean management as we know it today began with the Japanese manufacturing industry in the late 1940s, originating with the Toyota Production System (TPS). This system was designed to reduce processes that didn’t contribute to the product’s value, thus improving efficiency, productivity, and cost-effectiveness.

Toyota was initially a small automobile manufacturer that became a worldwide success. Over time, its business and operational processes caught on. Soon, other companies began to incorporate similar methodologies, hoping to experience the same levels of success that Toyota did.

The phrase “lean production” debuted in 1988. John Krafcik, the former CEO of Waymo, Google’s self-driving car project, used the term in his article “Triumph of the Lean Production System”.

Today, leading businesses worldwide use lean management, including Intel, John Deere, and Nike.

Lean Management Tools

Although there are many lean management tools to choose from, the following are the most popular:

The 5S Method

This Lean management method optimizes the working environment and reduces wasted time. It’s called the 5S method because of the Japanese translation:

• Seiri (organization)
• Seiton (order)
• Seiso (cleanliness)
• Seiketsu (standardization)
• Shitsuke (discipline)

The Lean Six Sigma Method

LSS improves process quality and efficiency. Combining the Lean manufacturing methodology and Six Sigma creates a complete system that eliminates waste and reduces process variation, resulting in streamlined manufacturing and optimal product output.

The Value Stream Mapping (VSM) Method

Value Strem Mapping analyzes processes and identifies obstacles. VSM involves visualizing, analyzing, and improving every step of every product or service delivery process.

The Kanban Method

Kanban is used to optimize inventory management. It defines, manages, and improves services that deliver knowledge work.

The Kaizen Method

Kaizen is a strategy where employees proactively work together to achieve regular, incremental, and continuous improvements in their manufacturing process.

The Visual Factory Method

Visual Factory uses visual displays, indicators, and controls throughout the manufacturing plant to improve information communication.

The SMED Method

Short for single-minute exchange of die, SMED reduces the series changeover time, shrinking it down to less than ten minutes. SMED is especially good for manufacturing in small lots, inventory reduction, and improved customer responsiveness.

Lean Management Examples

Lean management has proven its worth, including these examples:

• Healthcare. Healthcare is expensive and complicated, so more institutions are turning to lean management principles to improve cost-effectiveness, service quality, patient care, and healthcare workers’ satisfaction.
• Software Development. Lean principles mesh well with software development methodologies such as continuous deployment. Software and app development requires frequent releases, rapid turnaround times, and removing unnecessary and wasteful tasks. These needs jibe with the lean management philosophy.
• Startups. Getting a startup off the ground is a considerable challenge, fraught with risks and no guarantee of success. Therefore, the easier the road is, the greater the chance of success. Lean management’s five basic principles are a fantastic roadmap for any startup that wants to thrive and are especially effective in helping these embryonic organizations adjust to sudden changes.

Can Any Company Adopt a Lean Process Management Method?

While some management methodologies are designed for enterprise-level organizations, the lean management methodology can be adopted by any company. In many respects, it is the default way companies try to run. That is especially true for startups and small businesses that have little extra resources to waste.

The size of the company is not essential to this methodology. You can implement a lean management methodology across the entire company. And if everyone in the company works toward a lean management system, it still works.

The complexity of the company also doesn’t matter. Even the most complex multinational enterprises can benefit from adopting this system. It may even help resolve some of that complexity and help the company run more efficiently.

Lean Management Principles

Lean project management principles are simple, and there are only five. When adopting the methodology, address each one to get the best results. Here are the five principles of lean management.

Identify Value

Lean management always begins with identifying value. That just means finding the parts and processes in your business that create value. In this case, resting value means that a particular process takes the company closer to providing value to customers.

In retail, for example, this could be anything from ordering products to identifying which products customers want. However, keeping inventory that does not always sell in stock does not create value.

Before you can do anything to improve how the company works, you must know which parts add value and are worth keeping. Then, you can see where to remove different processes to make the business work more efficiently.

Value Stream Mapping

The next step is to identify the overall process that creates customer value. This usually means creating a step-by-step value stream map showing how the company creates value.

This is important because it shows how valuable parts of the business work together to deliver that value. In some cases, this may mean that steps in the process that you thought were not valuable provide some value rather than just to the customer.

Value mapping can also show where processes you thought added value might not be as valuable as you thought. By knowing the process of creating value, you can ensure that any changes made don’t stop the company from doing what it needs to do to keep customers happy.

Create a Continuous Workflow

When the value map is complete, the company can work on creating a continuous workflow. Workflows are always tricky to manage since things need to happen in a precise order to have positive results. Your goal at this point is to create a workflow where there are no pinch points in the process that slow things down.

Essentially, you are trying to make everything run smoothly from start to finish. Look for any areas in the process that create problems or take longer than they should. Finding processes that create time waste and making changes can make overall operations much smoother.

Create a Pull System

A pull system is designed to allocate work based on demand. This means that operations within the company only work on the services or products that are needed at the time and stop working when the demand for them drops.

Pull systems help optimize the use of resources and energy within the company. Companies can reduce waste and reduce production costs by focusing on where the demand is.

Continuous Improvement

Finally, lean management is a continuous system of improvement. Companies can continually improve optimization, so you should always look for new ways to improve performance.

This means creating a system to review performance regularly. Most companies have designated people to review performance metrics and look for new improvement methods. This is especially important when companies and industries go through significant changes.

Common Challenges When Implementing Lean Project Management

Lean management is a relatively straightforward management process. However, it can face considerable challenges when being implemented.

One of the most daunting challenges in implementing lean project management is from other staff within the company. Changing how a company runs is challenging since it involves retraining, removing, or firing staff because their current roles are made redundant. As you improve productivity throughout the company, the workers must adapt to changes that may not be needed.

If you are trying to implement lean management but are not the CEO, you could face significant pushback from above. People are skeptical of changes to a system that seems to work, and managers won’t want to act unless they are sure those changes will improve things. When developing lean management for your company, you’ll need to find a way to show management that those changes can make a big difference.

Lean Methodology: The 5 Principles Explained (and their Benefits)

11 min read · Updated on November 13, 2023

Can Lean methodology be the transformative approach your business needs to improve efficiency and profitability?

For business leaders and managers  tasked with improving their companies, there needs to be an ongoing effort to reduce waste and inefficiency. One of the most popular ways to focus on that mission is to employ Lean methodology principles. This comprehensive set of principles has a proven track record of creating value for customers while improving company efficiency, teamwork, and organizational culture. But what is Lean methodology and how can you implement its principles in your workplace?

In this post, we'll explore Lean methodology and its history, examine the five principles of this method, and consider some of its most important benefits. We'll also offer some invaluable tips that you can use to implement the Lean model in your company.

What is Lean methodology?

Lean methodology is a business strategy that enables companies to focus their attention on delivering more value to customers by reducing inefficiencies and improving productivity . At its core, it emphasizes appreciation for people - including employees and customers - and a belief that every aspect of business has room for improvement. The methodology is built around a set of principles and best practices that seek to eliminate waste from any company's workflow, to ensure that everything the company does provides real value to its customers.

The origins of the Lean model

Experts attribute the origin of Lean methodology to a single company: Toyota. More than seventy years ago, Toyota's leadership embarked on a mission to eliminate inefficiencies and focus their operations entirely on product value. They subsequently changed or eliminated every process that did not affirmatively contribute to providing more value to customers. Their efforts resulted in dramatic improvements to processes and the company's bottom line.

Decades later, the term Lean methodology was applied to Toyota's method as other companies began to experience similar levels of success by following the same principles.

What are the 5 principles of Lean methodology?

One of the most attractive features of Lean methodology is that the same five fundamental principles apply to almost all organizations, no matter the industry. Those principles include:

Identification of value

Everything starts with an effort to identify value within the company's processes. The goal is to ensure that the company can deliver its goods and services to customers at prices that they are willing to pay. This requires companies to know their customers and their desires, so that they understand how to meet those needs.

Mapping the value stream

With value identified, the next step is to map the entire value stream, from initial product concept and design to its purchase and use by customers. Companies need to understand a product's lifecycle if they are to identify waste that needs to be trimmed. The Lean method identifies all inefficiencies - defined as anything that fails to add real value to production processes - as waste which must be eliminated.

Waste can include unnecessary logistical obstacles, disorganization in the work process, imbalances in inventory, defects in production, a failure to properly use human resources, and other poor organizational and production practices. Companies that move to eliminate waste refocus their attention on optimizing value-added priorities like customer service, quality control, and other processes that help to satisfy customer needs.

Creating an efficient and continuous workflow

Once the value stream has been mapped out, the next step is to identify all those areas of waste that could potentially be trimmed. In many instances, each production process stage contains some level of inefficiency that can be improved. The process of systematically eliminating these instances of waste helps to create greater efficiency and a more continuous workflow. This occurs as different departments and stages of the production process come into more harmonious alignment with one another.

It's important to note that this process of improving value stream continuity is ongoing. The goal is to create and then maintain a synchronized workflow that ensures that production processes continue to flow in a way that maintains an efficient value stream. This smooth workflow enables a company to keep costs low, optimize production efficiencies, and deliver products to customers as they need them.

Developing a pull system

Any organization that continuously produced products at a steady rate would end up creating waste if it ended up producing more goods than the market can bear. To avoid that, Lean methodology requires the creation of a pull system. The pull system acts as a counterweight to the value stream and exists to ensure that your production does not exceed demand. This Lean principle only has employees working on production when demand requires it.

For example, Lean Agile methodology tools like Kanban boards can be used to create visual process flow representations to better manage workflow. These boards and similar tools can organize work in a visual way, to help managers and production teams focus on the right tasks at the right time. Pull systems and the tools that facilitate them are invaluable components in Lean methodology.

Prioritizing improvements

The fifth, and arguably the most important, principle of Lean methodology is that improvements need to be ongoing and continuous. When a company prioritizes these continuous improvements, it can ensure that inefficiencies don't creep back into production processes by targeting and eliminating potential problems before they become major challenges or systemic inefficiencies.

One example of this type of prioritization of improvement is the standard stand-up meeting that many large companies use to start each day. These meetings typically involve managers meeting with members of their team to highlight recent progress, discuss notable areas of concern, and provide forecasts about potential issues that may arise. When done properly, these meetings can improve team cohesion, raise awareness of potential problems, and motivate everyone to focus on desired process improvements.

What benefits can Lean provide?

Incorporating the Lean methodology into your company's organizational and operational processes can offer many advantages. To get a better understanding of how these principles could boost your company's efficiency and profitability, just consider the following potential benefits.

Improved interactions with customers

Lean methodology is necessarily focused on maximizing value for customers. As a result, the model requires open interactions with customers to determine their needs and monitor their satisfaction levels to ensure that company processes are meeting expectations. Consistent commitment to Lean can enable customers to always feel as though their needs are being considered, which creates the type of customer experience that fuels greater brand loyalty over time.

Reduced costs

Inefficiencies are a waste of resources like time, money, and manpower. Any effort that focuses on eliminating that waste will result in a lowering of cost, as unnecessary processes are changed or eliminated to improve efficiency. Ultimately, this reduced cost will help to increase profitability for the organization.

Less production errors

Since Lean principles typically lead to the elimination of inefficient processes, the methodology should reduce production errors. Remember, every part of the production process comes with a potential for mistakes to be made. A simplified process will provide fewer opportunities for errors to occur. That can lead to improved product quality and a subsequent boost in customer satisfaction.

Enhanced inventory and production control

By aggressively applying Lean methodology, companies can gain greater control over inventory management and production. By using pull systems to respond to customer demand, they can ensure that there are fewer products sitting in warehouses and that production is properly aligned with consumer needs.

Boosted employee morale

Many of the most successful companies understand the importance of ensuring that every team member's input on processes is heard and respected. Lean methodology can serve as a valuable avenue for inspiring employee engagement. That can boost morale , provide them with a renewed sense of empowerment, and encourage greater focus on high quality production.

Consistent improvements

One of the most important benefits companies can enjoy from applying Lean methodology principles is the avoidance of stagnation. Lean requires companies to continually evaluate their processes to identify potential waste, and that effectively creates a culture of improvement and innovation which can help to ensure that your company continues to focus on value.

Increased productivity

Because Lean methodology relies on improved team cohesion and engagement, it typically leads to improvements in production at the employee level. Team members who feel valued will be happier at work and more engaged in their roles. Over time, those increases in productivity  can create even greater efficiencies which have the potential to further enhance profitability.

Potential downsides of Lean methodology

Of course, no business methodology is without its potential downsides and Lean methodology is no exception. Moreover, the implementation of Lean can sometimes be a messy affair as employees, managers, and other stakeholders adjust to a new way of thinking. Below, we've outlined some of the most common potential issues that you might encounter when you begin to apply Lean methodology principles within your organization.

Immediate costs

For companies that are not accustomed to the principles of Lean, the initial implementation can be costly. Often, new equipment, technological systems, and software will need to be acquired to begin implementation. Managers and team members will need to undergo training to ensure that they have the knowledge and tools needed to make the transition. While those costs are often recouped over time, the initial expenditure can be a real challenge for many firms.

Transition obstacles

Big changes are always difficult, so it's important to remember that transition to Lean thinking may not occur as smoothly as you might like. Employees who are accustomed to doing things one way may not readily adapt to a new method. They may also struggle to focus on needed changes, since it can be difficult to identify waste when dealing with familiar processes.

Managerial unfamiliarity with Lean

For managers who are unfamiliar with Lean principles, implementation can sometimes result in excessive structuring. To avoid this, it is essential to invest time and resources to ensure that managers understand exactly how to compartmentalize and assess each of your production steps the right way.  

Obtaining team buy-in

You may find that some employees are resistant to the change you're seeking to implement. Familiarity can lead to complacency and employees who have been with your company for a long time may struggle to adapt to your vision. If you're going to implement Lean methodology, make sure that you've secured buy-in before you start.

Tips to help you implement the Lean model

Obviously, any manager or leader should carefully consider the pros and cons of Lean methodology before attempting to implement it within their company. If you've conducted that assessment and determined that Lean principles can help your organization to improve its processes, the following tips can help you with that implementation.

Bring your team along for the ride

Since you'll need your entire team to be on board with the change, you should communicate your goals to them and get their full buy-in. Be clear about your intent, the assistance you'll need from them, and your goal, and explain how the methodology can benefit them.

Start focusing on value now

There's no time like the present to begin focusing on value. Make the idea of product and process value an integral part of your thought process and communications to stakeholders. Successful implementation of the Lean methodology requires the right mindset, so start developing it immediately.

Commit to training

One way to boost employee engagement is to show them that you're committed to their development. Think about ways that you can offer training to your team members to show that dedication. By investing in them, you'll boost their morale, help them to focus on value, and make any transition to Lean principles a smoother process.

Could Lean methodology be the transformative change your company needs?

Like most living organisms, businesses need to grow and improve if they want to survive and thrive. The Lean methodology can provide a value-focused way to reduce inefficiencies, improve production, and increase profitability and customer satisfaction. If you're a manager or leader looking for an effective way to achieve those goals, Lean principles may offer the solution you need.

It combines Six Sigma methods and tools with the Lean manufacturing/ lean enterprise philosophy. It strives to eliminate the waste of physical resources, time, effort, and talent while assuring quality in production and organizational processes.

Simply put, Lean Six Sigma teaches that any use of resources that doesn’t create value for the end customer is considered a waste and should be eliminated.

Key Takeaways

• Lean Six Sigma seeks to improve employee and company performance by eliminating the waste of resources and process/product defects.
• It combines the process improvement methods of Six Sigma and Lean enterprise.
• Lean Six Sigma helps to establish a clear path to achieving improvement objectives.
• The Lean strategy was established by Toyota in the 1940s and attempts to streamline operational processes, from manufacturing to transactions.
• Six Sigma originated in the 1980s and seeks to improve output quality by reducing defects.

Lean Six Sigma is a combination of lean methodology and Six Sigma strategy. Lean methodology was established by Japanese automaker Toyota in the 1940s. Its purpose was to remove non-value-adding activities from the production process.

Six Sigma, on the other hand, was established in 1986 by an engineer at U.S. telecommunications company Motorola who was inspired by Japan’s Kaizen model. It was trademarked by the company in 1993. Its method seeks to identify and reduce defects in the production process. It also strives to streamline the variability of the production process.

Lean Six Sigma emerged in the 1990s as large U.S. manufacturers attempted to compete with Japan’s better-made products. The combination strategy was introduced by Michael George and Robert Lawrence Jr. in their 2002 book "Lean Six Sigma: Combining Six Sigma With Lean Speed . "

Companies can arrange for Lean Six Sigma training and certification from a wide selection of organizations that specialize in the approaches of Lean Six Sigma and Six Sigma.

The Lean Six Sigma Concept

The Lean concept of management focuses on the reduction and elimination of eight kinds of waste known as “DOWNTIME,” an acronym for [ Clay: Is there no word for the "D"? Jenny ] overproduction, waiting, non-utilized talent, transportation, inventory, motion, and extra-processing. Lean refers to any method, measure, or tool that helps in the identification and elimination of waste.

The term “Six Sigma” refers to tools and techniques that are used to improve manufacturing processes. The strategy attempts to identify and eliminate the causes of defects and variations in business and manufacturing processes.

Six Sigma’s DMAIC phases are utilized in Lean Six Sigma. The acronym stands for define, measure, analyze, improve, and control (see "Lean Six Sigma Phases," below). It refers to the data-driven five-step method for improving, optimizing, and stabilizing business and manufacturing processes.

A Lean Six Sigma approach that combines lean strategy and Six Sigma’s tools and techniques highlights processes that are prone to waste, defects, and variation and then reduces them to ensure improvement in a company’s operational processes.

Lean Six Sigma Techniques

The techniques and tools used to accomplish essential goals of the Lean Six Sigma strategy include:

• Kanban : Kanban involves workflow management practices, such as work visualization and limited work in progress, which maximize efficiency and promote continuous improvement.
• Kaizen : “ Kaizen ” is a Japanese word that denotes change for the better or continuous improvement. Practices that engage employees and promote a work environment that emphasizes self-development and ongoing improvement are its focus.
• Value stream mapping : This analyzes places to eliminate waste and optimize process steps.
• 5S tool : This is a method to ensure that the workplace is efficient, productive, safe, and successful.

Lean Six Sigma Just-In-Time (JIT) training allows employees to focus resources on what customers need and when they need it, rather than building up unnecessary inventory.

Lean Six Sigma Phases

The DMAIC phases of Lean Six Sigma are used to identify and improve existing process problems with unknown root causes.

Define the problem from a company perspective, stakeholder perspective, and customer perspective. Figure out the quality expectations that customers have and the extent of the problem.

Examine the current process and how it contributes to the problem. Determine whether the process can meet customers' previously defined quality expectations. Match each process step to your quality criteria. Support your measurements with actual performance data.

Examine all information gathered thus far to finalize the exact nature of the problem, its scope, and its cause.

Solve the problem and verify the improvement. Collaborate to structure a solution that eliminates both the problem and its cause. Use your data to ensure that the solution fits the issue at hand. Test the solution and derive performance data to support it.

Monitor improvement and continue to improve where possible. Finalize acceptable performance criteria. Establish a plan that can deal with variations that occur, sustain improvements, and prevent a reoccurrence of the original problem.

DMAIC works best when used to solve a problem relating to a process, quality, or waste issue in an organization.

Lean Six Sigma Belt Levels

Lean Six Sigma training uses belts to denote Lean Six Sigma expertise. The exact specifications for each belt may differ depending on what organization provides the certification.

Benefits of Lean Six Sigma

There are a number of established benefits to Lean Six Sigma methods for employees, customers, vendors, and the company.

By increasing the efficiency of important processes, companies can improve the work experience for employees and the customer experience for buyers. This can build loyalty inside and outside of a company.

Streamlined, simplified processes can increase control and a company’s ability to capitalize on new opportunities quickly. They can also lead to more sales and revenue, lower costs, and more successful business results.

Involving employees in a group or a company-wide efficiency effort can improve their skills (e.g., analytical thinking and project management) and growth opportunities while boosting camaraderie. By preventing defects, companies save on the time, money, and human effort previously required to identify and eliminate them.

Lean Six Sigma and Six Sigma are two related strategies that can solve process problems. Both can help companies make noteworthy improvements in quality, efficiency, and use of time by analyzing the way their processes function. Both use the DMAIC phases/method. Both are based on creating a problem-solving workplace culture.

However, Six Sigma is focused on reducing defects and process variability to improve process output and quality to meet customer expectations. Lean Six Sigma is focused on reducing or eliminating the wasteful use of resources and defects to improve workflow and create more value for customers.

Lean Six Sigma combines aspects of Six Sigma (such as data analysis) and aspects of the Lean methodology (such as waste-eliminating tools) to improve process flow, maintain continuous improvement, and achieve business goals.

What Is the Meaning of Lean Six Sigma?

Lean Six Sigma is a process improvement strategy that seeks to eliminate inefficiencies in a company’s process flow by identifying the causes of waste or redundancy and developing solutions to address them.

What Are the Five Principles of Lean Six Sigma?

Define, measure, analyze, improve, and control are the five principles and phases of Lean Six Sigma. They’re the steps practitioners take to create more efficient processes and a workplace culture that’s focused on continuous improvement.

Why Is Lean Six Sigma Important?

Many consider Lean Six Sigma important for the measurable and consistent improvements in operations and business results that companies achieve using it. It also might be considered important because it combines the significant process streamlining of the Lean methodology of the 1940s with the Six Sigma data-driven approach of the 1980s.

What Is Lean Six Sigma Training?

Lean Six Sigma training instructs students in the basics of Six Sigma methodology, as well as the Six Sigma DMAIC roadmap. Students also learn how to apply the concepts in practical scenarios as they go through the courses.

In business, the term Lean  has been applied to everything from product development to human resources. In the world of software development and project management, Lean development is a methodology that reduces waste and increases eff iciency throughout the software development life cycle (SDLC) . This project management tutorial talks about Lean development and how it can benefit your business.

Interested in becoming a certified project manager? We have a list of the Top Project Management Certifications to help get you started.

Lean development is a software development process focusing on efficiency and waste reduction. The primary purpose of Lean development is to reduce the time and resources needed to build and deploy software.

The basic tenets of Lean development are similar to those of the Toyota Production System : focus on eliminating waste, continuous improvement, and delivering value to the customer. Additionally, Lean development can help improve communication and collaboration between the members, project manager, and developers of your team.

Lean development has its detractors, who argue that the methodology is too rigid and does not allow for sufficient creativity. However, there are many companies who have successfully implemented Lean principles and have reaped the benefits of improved efficiency and quality.

History of Lean Development

Lean development is a methodology that has its roots in the manufacturing sector. The term “lean” was first coined by Toyota executive Taiichi Ohno, who is credited with developing the Toyota Production System . The primary objective of this methodology is to eliminate waste and optimize manufacturing processes.

Ohno’s philosophy of Lean thinking soon spread beyond the automotive industry, and Lean principles have been applied to a variety of different business sectors, including software development and project management.

Benefits of Lean Development and Project Management

The benefits of using Lean development and project management include faster software delivery, improved quality of the final product, and reduced costs. Other benefits of Lean software development include:

• Increased Efficiency : By eliminating waste and focusing on essential tasks, Lean development helps teams work more efficiently. This can lead to shorter development cycles and faster time-to-market.
• Improved Quality : Streamlining the development process helps ensure that only essential features are built into the final product. Consequently, customers are more likely to receive quality products that meet their needs.
• Lean Development enables organizations to reduce waste and efficiency, thereby reducing costs. Hence, you can move your resources to other projects if required.
• Increased Customer Satisfaction : Delivering better quality products fast can increase customer satisfaction. This, in turn, can lead to repeat business and improved brand loyalty.
• Improved Morale : By streamlining the development process and eliminating waste, Lean development can help improve employee morale, leading to a more positive work environment.

What are the Downsides of Lean Development?

One downside is that Lean development can lead to a “ship it now, fix it later” mentality, which can result in lower quality products. Additionally, because Lean development relies heavily on customer feedback, it can be difficult to please everyone and meet all expectations.

Lean development can be difficult to implement because it requires you to change how you work, which means changing a developer’s habits and routines. This requires buy-in from all stakeholders on the team—people need time and energy before they are willing to change their habits.

How to Implement Lean Development and Project Management

If you are looking to implement Lean development in your organization, there are a few key things to keep in mind. The importance of understanding Lean development and the advantages it can provide to your organization cannot be overstated.

Once you thoroughly grasp the basics, you can begin implementing some of the key practices into your workflow. Lean development emphasizes continuous improvement. This means constantly assessing your work process and looking for ways to improve it.

This might involve minor changes to your daily work or more significant changes, such as adopting new tools or processes. If you want to be more efficient, you should always try to streamline your workflow in order to make it more effective.

Another key element of Lean development is collaboration. It is common for lean development teams to consist of cross-functional members who work together to accomplish their goals. You should adopt a collaborative approach to be successful. To help in that endeavor, we have a great list of the Top Collaboration Tools for Developers .

If you are a project manager or developer interested in implementing Lean development principles, start by researching and incorporating some critical practices into your workflow. You can soon reap the benefits of this robust methodology with little effort.

• Preserving refinement necessitates leadership backing, change management , and unrelenting surveillance adjusting.

What is the Continuous Improvement Model?

Amid fluid commercial landscapes, enterprises must repeatedly refine operations to retain competitors’ edge. This inspires continuous betterment paradigms.

Continuous improvement model denotes a philosophy and methodology enhancing fare through incessant progression. Adopting models boosts proficiency while slashing waste and energizing originality.

Notions arise from quality-centered ideologies like Lean, Six Sigma , and Toyota—targeting scrap, diversity, and inefficient moves amid operations.

Models chart a disciplined refinement framework. Cyclical planning/executing/surveilling/modifying amid data and responses characterizes progress.

Demographics incorporate PDCA , Kaizen , Lean Six Sigma, and DMAIC —diverse yet synchronizing fundamental additive refinement.

Correct implementation necessitates cultural reconfiguration motivating employee problem-solving and unending quests for mastery.

By embracing advancement steadfastly, enterprises achieve sustainable growth, more delighted buyers, and leadership amid unpredictability through improvisational skills navigating variability.

Continuous Improvement Tools and Techniques

Successful continuous improvement model requires the right tools and techniques to identify opportunities, analyze problems, implement solutions, and sustain gains. Some powerful continuous improvement tools and methodologies include:

Lean Six Sigma : This data-driven approach combines lean manufacturing/lean enterprise techniques with Six Sigma’s rigorous focus on reducing defects and process variations . Tools like value stream mapping , 5S , and DMAIC are core to Lean Six Sigma.

Kaizen : The Japanese philosophy of kaizen emphasizes ongoing, incremental changes and empowering employees at all levels to identify and act on improvement opportunities. Kaizen techniques include kaizen events/blitzes, Gemba walks , and quality circles.

Root Cause Analysis : Techniques like fishbone (cause-and-effect) diagrams , the 5 Whys , fault tree analysis , and others help teams drill down to the true underlying causes of problems rather than just addressing symptoms.

Statistical Process Control : Tools like control charts , capability analysis , and hypothesis testing provide a statistical framework for monitoring process performance and variation over time .

Poka-Yoke (Mistake-Proofing) : These techniques, like using physical devices or mechanisms, aim to prevent errors and defects from occurring in the first place.

Hoshin Kanri (Policy Deployment) : This methodology ensures that continuous improvement efforts are aligned with and driven by the organization’s overarching goals and strategic direction.

Voice of the Customer : Surveys, interviews, ethnography, and other techniques capture customer needs , expectations, and dissatisfactions to prioritize improvements.

The key is having a structured way to identify opportunities, get to root causes, develop countermeasures, and follow up to hold the gains.

Implementing Continuous Improvement Model

Adopting a continuous improvement model requires a systematic approach and commitment from all levels of an organization. The following steps can help effectively implement continuous improvement model:

Define Goals and Metrics for Continuous Improvement Model

Before embarking on any improvement initiative, it’s crucial to establish clear goals aligned with the organization’s strategic objectives.

These goals should be specific, measurable, achievable, relevant, and time-bound ( SMART ). Additionally, define the key performance indicators (KPIs) that will measure progress and success.

Gain Leadership Buy-In  

Continuous improvement efforts require strong leadership support and active involvement. Leaders should communicate the vision, allocate necessary resources, and serve as role models, encouraging and recognizing improvement efforts.

Build a Culture of Continuous Improvement

Creating a culture that embraces continuous improvement is essential. This involves training employees on continuous improvement model/methodologies, encouraging idea generation, and recognizing and rewarding improvement efforts. Employee empowerment and engagement are key drivers of success.

Map and Analyze Processes for Continuous Improvement Model  

Identify and document the critical processes within the organization. Use techniques like value stream mapping and process flow diagrams to visualize and analyze these processes, identifying areas for improvement, waste elimination, and optimization opportunities.

Prioritize Improvement Projects

Based on the process analysis and alignment with organizational goals, prioritize improvement projects. Consider factors such as potential impact, resource requirements, and project complexity when determining the priority order.

Assemble Cross-Functional Teams

Continuous improvement initiatives often require cross-functional collaboration . Assemble teams with representatives from different departments or functions affected by the targeted process. This diversity of perspectives and expertise fosters more comprehensive solutions.

Use Continuous Improvement Tools and Techniques

Leverage various continuous improvement tools and methodologies, such as Lean Six Sigma, Kaizen , PDCA (Plan-Do-Check-Act) cycle , root cause analysis , and others, to drive improvements systematically.

Implement and Monitor Improvements

Once improvement solutions are identified, develop an implementation plan, allocate resources, and execute the changes. Continuously monitor progress, measure results against the defined KPIs, and make necessary adjustments.

Standardize and Sustain Improvements with the Continuous Improvement Model

After successful implementation, standardize the improved processes and integrate them into the organization’s operations. Develop mechanisms to sustain the improvements, such as regular audits, training programs, and continuous monitoring.

Foster Continuous Learning and Knowledge Sharing

Encourage continuous learning by capturing lessons learned, sharing best practices, and celebrating successes. This helps reinforce the continuous improvement culture and facilitates knowledge transfer across the organization.

Sustaining Continuous Improvement

Creating a culture of continuous improvement is critical for the long-term success of any continuous improvement initiative. Even after implementing new processes and seeing great results, it can be easy to become complacent and revert to old ways of working. To sustain continuous improvement, organizations must ingrain it into their culture and values.

Employee Empowerment and Engagement

Frontline employees are closest to the processes and have valuable insights into areas for improvement. Empowering and engaging employees at all levels is key to identifying continuous improvement opportunities. This can involve training on continuous improvement methodologies, giving employees a voice in process changes, and rewarding those who drive improvements.

Leadership Support for Continuous Improvement Model

Support from top leadership is vital for sustaining a continuous improvement culture . Leaders must exemplify the principles, provide training and resources, celebrate successes, and ensure continuous improvement model is a strategic priority across the organization.

Continuous Improvement Model as a Core Value

Continuous improvement cannot just be a program or initiative – it must become a core value ingrained in the company’s DNA. It should be part of the onboarding process, regularly discussed in meetings, and tied to performance goals and compensation.

Tracking and Accountability

Implementing tracking mechanisms and creating accountability for continuous improvement model is important. This could involve visual management systems, periodic audits and benchmarking against best practices. Celebrating wins and sharing results widely helps motivate the organization.

Dedicated Resources

While every employee should be responsible for continuous improvement, having dedicated resources like a continuous improvement team or black belts helps institutionalize it. This team can develop training, drive projects, and ensure efforts don’t get deprioritized.
