Similarly, farmers in countries like Ireland use satellite-based information to ditch traditional methods and multiply their yield strategically.  

11. Data Science in the Transportation Industry   

Transportation keeps the world moving around. People and goods commute from one place to another for various purposes, and it is fair to say that the world will come to a standstill without efficient transportation. That is why it is crucial to keep the transportation industry in the most smoothly working pattern, and data science helps a lot in this. In the realm of technological progress, various devices such as traffic sensors, monitoring display systems, mobility management devices, and numerous others have emerged.  

Many cities have already adapted to the multi-modal transportation system. They use GPS trackers, geo-locations and CCTV cameras to monitor and manage their transportation system. Uber is the perfect case study to understand the use of data science in the transportation industry. They optimize their ride-sharing feature and track the delivery routes through data analysis. Their data science approach enabled them to serve more than 100 million users, making transportation easy and convenient. Moreover, they also use the data they fetch from users daily to offer cost-effective and quickly available rides.  

12. Data Science in the Environmental Industry

Data Analytics Case Study: Complete Guide in 2024

What are data analytics case study interviews.

When you’re trying to land a data analyst job, the last thing to stand in your way is the data analytics case study interview.

One reason they’re so challenging is that case studies don’t typically have a right or wrong answer.

Instead, case study interviews require you to come up with a hypothesis for an analytics question and then produce data to support or validate your hypothesis. In other words, it’s not just about your technical skills; you’re also being tested on creative problem-solving and your ability to communicate with stakeholders.

This article provides an overview of how to answer data analytics case study interview questions. You can find an in-depth course in the data analytics learning path .

How to Solve Data Analytics Case Questions

Check out our video below on How to solve a Data Analytics case study problem:

With data analyst case questions, you will need to answer two key questions:

• What metrics should I propose?
• How do I write a SQL query to get the metrics I need?

In short, to ace a data analytics case interview, you not only need to brush up on case questions, but you also should be adept at writing all types of SQL queries and have strong data sense.

These questions are especially challenging to answer if you don’t have a framework or know how to answer them. To help you prepare, we created this step-by-step guide to answering data analytics case questions.

We show you how to use a framework to answer case questions, provide example analytics questions, and help you understand the difference between analytics case studies and product metrics case studies .

Data Analytics Cases vs Product Metrics Questions

Product case questions sometimes get lumped in with data analytics cases.

Ultimately, the type of case question you are asked will depend on the role. For example, product analysts will likely face more product-oriented questions.

Product metrics cases tend to focus on a hypothetical situation. You might be asked to:

Investigate Metrics - One of the most common types will ask you to investigate a metric, usually one that’s going up or down. For example, “Why are Facebook friend requests falling by 10 percent?”

Measure Product/Feature Success - A lot of analytics cases revolve around the measurement of product success and feature changes. For example, “We want to add X feature to product Y. What metrics would you track to make sure that’s a good idea?”

With product data cases, the key difference is that you may or may not be required to write the SQL query to find the metric.

Instead, these interviews are more theoretical and are designed to assess your product sense and ability to think about analytics problems from a product perspective. Product metrics questions may also show up in the data analyst interview , but likely only for product data analyst roles.

TRY CHECKING: Marketing Analytics Case Study Guide

Data Analytics Case Study Question: Sample Solution

Let’s start with an example data analytics case question :

You’re given a table that represents search results from searches on Facebook. The query column is the search term, the position column represents each position the search result came in, and the rating column represents the human rating from 1 to 5, where 5 is high relevance, and 1 is low relevance.

Each row in the search_events table represents a single search, with the has_clicked column representing if a user clicked on a result or not. We have a hypothesis that the CTR is dependent on the search result rating.

Write a query to return data to support or disprove this hypothesis.

search_results table:

search_events table

Step 1: With Data Analytics Case Studies, Start by Making Assumptions

Hint: Start by making assumptions and thinking out loud. With this question, focus on coming up with a metric to support the hypothesis. If the question is unclear or if you think you need more information, be sure to ask.

Answer. The hypothesis is that CTR is dependent on search result rating. Therefore, we want to focus on the CTR metric, and we can assume:

• If CTR is high when search result ratings are high, and CTR is low when the search result ratings are low, then the hypothesis is correct.
• If CTR is low when the search ratings are high, or there is no proven correlation between the two, then our hypothesis is not proven.

Step 2: Provide a Solution for the Case Question

Hint: Walk the interviewer through your reasoning. Talking about the decisions you make and why you’re making them shows off your problem-solving approach.

Answer. One way we can investigate the hypothesis is to look at the results split into different search rating buckets. For example, if we measure the CTR for results rated at 1, then those rated at 2, and so on, we can identify if an increase in rating is correlated with an increase in CTR.

First, I’d write a query to get the number of results for each query in each bucket. We want to look at the distribution of results that are less than a rating threshold, which will help us see the relationship between search rating and CTR.

This CTE aggregates the number of results that are less than a certain rating threshold. Later, we can use this to see the percentage that are in each bucket. If we re-join to the search_events table, we can calculate the CTR by then grouping by each bucket.

Step 3: Use Analysis to Backup Your Solution

Hint: Be prepared to justify your solution. Interviewers will follow up with questions about your reasoning, and ask why you make certain assumptions.

Answer. By using the CASE WHEN statement, I calculated each ratings bucket by checking to see if all the search results were less than 1, 2, or 3 by subtracting the total from the number within the bucket and seeing if it equates to 0.

I did that to get away from averages in our bucketing system. Outliers would make it more difficult to measure the effect of bad ratings. For example, if a query had a 1 rating and another had a 5 rating, that would equate to an average of 3. Whereas in my solution, a query with all of the results under 1, 2, or 3 lets us know that it actually has bad ratings.

Product Data Case Question: Sample Solution

In product metrics interviews, you’ll likely be asked about analytics, but the discussion will be more theoretical. You’ll propose a solution to a problem, and supply the metrics you’ll use to investigate or solve it. You may or may not be required to write a SQL query to get those metrics.

We’ll start with an example product metrics case study question :

Let’s say you work for a social media company that has just done a launch in a new city. Looking at weekly metrics, you see a slow decrease in the average number of comments per user from January to March in this city.

The company has been consistently growing new users in the city from January to March.

What are some reasons why the average number of comments per user would be decreasing and what metrics would you look into?

Step 1: Ask Clarifying Questions Specific to the Case

Hint: This question is very vague. It’s all hypothetical, so we don’t know very much about users, what the product is, and how people might be interacting. Be sure you ask questions upfront about the product.

Answer: Before I jump into an answer, I’d like to ask a few questions:

• Who uses this social network? How do they interact with each other?
• Has there been any performance issues that might be causing the problem?
• What are the goals of this particular launch?
• Has there been any changes to the comment features in recent weeks?

For the sake of this example, let’s say we learn that it’s a social network similar to Facebook with a young audience, and the goals of the launch are to grow the user base. Also, there have been no performance issues and the commenting feature hasn’t been changed since launch.

Step 2: Use the Case Question to Make Assumptions

Hint: Look for clues in the question. For example, this case gives you a metric, “average number of comments per user.” Consider if the clue might be helpful in your solution. But be careful, sometimes questions are designed to throw you off track.

Answer: From the question, we can hypothesize a little bit. For example, we know that user count is increasing linearly. That means two things:

• The decreasing comments issue isn’t a result of a declining user base.
• The cause isn’t loss of platform.

We can also model out the data to help us get a better picture of the average number of comments per user metric:

• January: 10000 users, 30000 comments, 3 comments/user
• February: 20000 users, 50000 comments, 2.5 comments/user
• March: 30000 users, 60000 comments, 2 comments/user

One thing to note: Although this is an interesting metric, I’m not sure if it will help us solve this question. For one, average comments per user doesn’t account for churn. We might assume that during the three-month period users are churning off the platform. Let’s say the churn rate is 25% in January, 20% in February and 15% in March.

Step 3: Make a Hypothesis About the Data

Hint: Don’t worry too much about making a correct hypothesis. Instead, interviewers want to get a sense of your product initiation and that you’re on the right track. Also, be prepared to measure your hypothesis.

Answer. I would say that average comments per user isn’t a great metric to use, because it doesn’t reveal insights into what’s really causing this issue.

That’s because it doesn’t account for active users, which are the users who are actually commenting. A better metric to investigate would be retained users and monthly active users.

What I suspect is causing the issue is that active users are commenting frequently and are responsible for the increase in comments month-to-month. New users, on the other hand, aren’t as engaged and aren’t commenting as often.

Step 4: Provide Metrics and Data Analysis

Hint: Within your solution, include key metrics that you’d like to investigate that will help you measure success.

Answer: I’d say there are a few ways we could investigate the cause of this problem, but the one I’d be most interested in would be the engagement of monthly active users.

If the growth in comments is coming from active users, that would help us understand how we’re doing at retaining users. Plus, it will also show if new users are less engaged and commenting less frequently.

One way that we could dig into this would be to segment users by their onboarding date, which would help us to visualize engagement and see how engaged some of our longest-retained users are.

If engagement of new users is the issue, that will give us some options in terms of strategies for addressing the problem. For example, we could test new onboarding or commenting features designed to generate engagement.

Step 5: Propose a Solution for the Case Question

Hint: In the majority of cases, your initial assumptions might be incorrect, or the interviewer might throw you a curveball. Be prepared to make new hypotheses or discuss the pitfalls of your analysis.

Answer. If the cause wasn’t due to a lack of engagement among new users, then I’d want to investigate active users. One potential cause would be active users commenting less. In that case, we’d know that our earliest users were churning out, and that engagement among new users was potentially growing.

Again, I think we’d want to focus on user engagement since the onboarding date. That would help us understand if we were seeing higher levels of churn among active users, and we could start to identify some solutions there.

Tip: Use a Framework to Solve Data Analytics Case Questions

Analytics case questions can be challenging, but they’re much more challenging if you don’t use a framework. Without a framework, it’s easier to get lost in your answer, to get stuck, and really lose the confidence of your interviewer. Find helpful frameworks for data analytics questions in our data analytics learning path and our product metrics learning path .

Once you have the framework down, what’s the best way to practice? Mock interviews with our coaches are very effective, as you’ll get feedback and helpful tips as you answer.

3 Action Items You Need To Take

To actually use the data analysis case study you’re about to get – you need to take 3 main steps. Those are:

• Reflect upon your organization as it is today (I left you some prompts below – to help you get started)
• Review winning data case collections (starting with the one I’m sharing here) and identify 5 that seem the most promising for your organization given it’s current set-up
• Assess your organization AND those 5 winning case collections. Based on that assessment, select the “QUICK WIN” data use case that offers your organization the most bang for it’s buck

Step 1: Reflect Upon Your Organization

Whenever you evaluate data case collections to decide if they’re a good fit for your organization, the first thing you need to do is organize your thoughts with respect to your organization as it is today.

Before moving into the data analysis case study, STOP and ANSWER THE FOLLOWING QUESTIONS – just to remind yourself:

• What is the business vision for our organization?
• What industries do we primarily support?
• What data technologies do we already have up and running, that we could use to generate even more value?
• What team members do we have to support a new data project? And what are their data skillsets like?
• What type of data are we mostly looking to generate value from? Structured? Semi-Structured? Un-structured? Real-time data? Huge data sets? What are our data resources like?

Jot down some notes while you’re here. Then keep them in mind as you read on to find out how one company, Humana, used its data to achieve a 28 percent increase in customer satisfaction. Also include its 63 percent increase in employee engagement! (That’s such a seriously impressive outcome, right?!)

Step 2: Review Data Case Studies

Here we are, already at step 2. It’s time for you to start reviewing data analysis case studies  (starting with the one I’m sharing below). I dentify 5 that seem the most promising for your organization given its current set-up.

Humana’s Automated Data Analysis Case Study

The key thing to note here is that the approach to creating a successful data program varies from industry to industry .

Let’s start with one to demonstrate the kind of value you can glean from these kinds of success stories.

Humana has provided health insurance to Americans for over 50 years. It is a service company focused on fulfilling the needs of its customers. A great deal of Humana’s success as a company rides on customer satisfaction, and the frontline of that battle for customers’ hearts and minds is Humana’s customer service center.

Call centers are hard to get right. A lot of emotions can arise during a customer service call, especially one relating to health and health insurance. Sometimes people are frustrated. At times, they’re upset. Also, there are times the customer service representative becomes aggravated, and the overall tone and progression of the phone call goes downhill. This is of course very bad for customer satisfaction.

Humana wanted to use artificial intelligence to improve customer satisfaction (and thus, customer retention rates & profits per customer).

Humana wanted to find a way to use artificial intelligence to monitor their phone calls and help their agents do a better job connecting with their customers in order to improve customer satisfaction (and thus, customer retention rates & profits per customer ).

In light of their business need, Humana worked with a company called Cogito, which specializes in voice analytics technology.

Cogito offers a piece of AI technology called Cogito Dialogue. It’s been trained to identify certain conversational cues as a way of helping call center representatives and supervisors stay actively engaged in a call with a customer.

The AI listens to cues like the customer’s voice pitch.

If it’s rising, or if the call representative and the customer talk over each other, then the dialogue tool will send out electronic alerts to the agent during the call.

Humana fed the dialogue tool customer service data from 10,000 calls and allowed it to analyze cues such as keywords, interruptions, and pauses, and these cues were then linked with specific outcomes. For example, if the representative is receiving a particular type of cues, they are likely to get a specific customer satisfaction result.

The Outcome

Customers were happier, and customer service representatives were more engaged..

This automated solution for data analysis has now been deployed in 200 Humana call centers and the company plans to roll it out to 100 percent of its centers in the future.

The initiative was so successful, Humana has been able to focus on next steps in its data program. The company now plans to begin predicting the type of calls that are likely to go unresolved, so they can send those calls over to management before they become frustrating to the customer and customer service representative alike.

What does this mean for you and your business?

Well, if you’re looking for new ways to generate value by improving the quantity and quality of the decision support that you’re providing to your customer service personnel, then this may be a perfect example of how you can do so.

Humana’s Business Use Cases

Humana’s data analysis case study includes two key business use cases:

• Analyzing customer sentiment; and
• Suggesting actions to customer service representatives.

Analyzing Customer Sentiment

First things first, before you go ahead and collect data, you need to ask yourself who and what is involved in making things happen within the business.

In the case of Humana, the actors were:

• The health insurance system itself
• The customer, and
• The customer service representative

As you can see in the use case diagram above, the relational aspect is pretty simple. You have a customer service representative and a customer. They are both producing audio data, and that audio data is being fed into the system.

Humana focused on collecting the key data points, shown in the image below, from their customer service operations.

By collecting data about speech style, pitch, silence, stress in customers’ voices, length of call, speed of customers’ speech, intonation, articulation, silence, and representatives’  manner of speaking, Humana was able to analyze customer sentiment and introduce techniques for improved customer satisfaction.

Having strategically defined these data points, the Cogito technology was able to generate reports about customer sentiment during the calls.

Suggesting actions to customer service representatives.

The second use case for the Humana data program follows on from the data gathered in the first case.

In Humana’s case, Cogito generated a host of call analyses and reports about key call issues.

In the second business use case, Cogito was able to suggest actions to customer service representatives, in real-time , to make use of incoming data and help improve customer satisfaction on the spot.

The technology Humana used provided suggestions via text message to the customer service representative, offering the following types of feedback:

• The tone of voice is too tense
• The speed of speaking is high
• The customer representative and customer are speaking at the same time

These alerts allowed the Humana customer service representatives to alter their approach immediately , improving the quality of the interaction and, subsequently, the customer satisfaction.

The preconditions for success in this use case were:

• The call-related data must be collected and stored
• The AI models must be in place to generate analysis on the data points that are recorded during the calls

Evidence of success can subsequently be found in a system that offers real-time suggestions for courses of action that the customer service representative can take to improve customer satisfaction.

Thanks to this data-intensive business use case, Humana was able to increase customer satisfaction, improve customer retention rates, and drive profits per customer.

The Technology That Supports This Data Analysis Case Study

I promised to dip into the tech side of things. This is especially for those of you who are interested in the ins and outs of how projects like this one are actually rolled out.

Here’s a little rundown of the main technologies we discovered when we investigated how Cogito runs in support of its clients like Humana.

• For cloud data management Cogito uses AWS, specifically the Athena product
• For on-premise big data management, the company used Apache HDFS – the distributed file system for storing big data
• They utilize MapReduce, for processing their data
• And Cogito also has traditional systems and relational database management systems such as PostgreSQL
• In terms of analytics and data visualization tools, Cogito makes use of Tableau
• And for its machine learning technology, these use cases required people with knowledge in Python, R, and SQL, as well as deep learning (Cogito uses the PyTorch library and the TensorFlow library)

These data science skill sets support the effective computing, deep learning , and natural language processing applications employed by Humana for this use case.

If you’re looking to hire people to help with your own data initiative, then people with those skills listed above, and with experience in these specific technologies, would be a huge help.

Step 3: S elect The “Quick Win” Data Use Case

Still there? Great!

It’s time to close the loop.

Remember those notes you took before you reviewed the study? I want you to STOP here and assess. Does this Humana case study seem applicable and promising as a solution, given your organization’s current set-up…

YES ▶ Excellent!

Earmark it and continue exploring other winning data use cases until you’ve identified 5 that seem like great fits for your businesses needs. Evaluate those against your organization’s needs, and select the very best fit to be your “quick win” data use case. Develop your data strategy around that.

NO , Lillian – It’s not applicable. ▶  No problem.

Discard the information and continue exploring the winning data use cases we’ve categorized for you according to business function and industry. Save time by dialing down into the business function you know your business really needs help with now. Identify 5 winning data use cases that seem like great fits for your businesses needs. Evaluate those against your organization’s needs, and select the very best fit to be your “quick win” data use case. Develop your data strategy around that data use case.

8 case studies and real world examples of how Big Data has helped keep on top of competition

Fast, data-informed decision-making can drive business success. Managing high customer expectations, navigating marketing challenges, and global competition – many organizations look to data analytics and business intelligence for a competitive advantage.

Using data to serve up personalized ads based on browsing history, providing contextual KPI data access for all employees and centralizing data from across the business into one digital ecosystem so processes can be more thoroughly reviewed are all examples of business intelligence.

Organizations invest in data science because it promises to bring competitive advantages.

Data is transforming into an actionable asset, and new tools are using that reality to move the needle with ML. As a result, organizations are on the brink of mobilizing data to not only predict the future but also to increase the likelihood of certain outcomes through prescriptive analytics.

Here are some case studies that show some ways BI is making a difference for companies around the world:

1) Starbucks:

With 90 million transactions a week in 25,000 stores worldwide the coffee giant is in many ways on the cutting edge of using big data and artificial intelligence to help direct marketing, sales and business decisions

Through its popular loyalty card program and mobile application, Starbucks owns individual purchase data from millions of customers. Using this information and BI tools, the company predicts purchases and sends individual offers of what customers will likely prefer via their app and email. This system draws existing customers into its stores more frequently and increases sales volumes.

The same intel that helps Starbucks suggest new products to try also helps the company send personalized offers and discounts that go far beyond a special birthday discount. Additionally, a customized email goes out to any customer who hasn’t visited a Starbucks recently with enticing offers—built from that individual’s purchase history—to re-engage them.

2) Netflix:

The online entertainment company’s 148 million subscribers give it a massive BI advantage.

Netflix has digitized its interactions with its 151 million subscribers. It collects data from each of its users and with the help of data analytics understands the behavior of subscribers and their watching patterns. It then leverages that information to recommend movies and TV shows customized as per the subscriber’s choice and preferences.

As per Netflix, around 80% of the viewer’s activity is triggered by personalized algorithmic recommendations. Where Netflix gains an edge over its peers is that by collecting different data points, it creates detailed profiles of its subscribers which helps them engage with them better.

The recommendation system of Netflix contributes to more than 80% of the content streamed by its subscribers which has helped Netflix earn a whopping one billion via customer retention. Due to this reason, Netflix doesn’t have to invest too much on advertising and marketing their shows. They precisely know an estimate of the people who would be interested in watching a show.

3) Coca-Cola:

Coca Cola is the world’s largest beverage company, with over 500 soft drink brands sold in more than 200 countries. Given the size of its operations, Coca Cola generates a substantial amount of data across its value chain – including sourcing, production, distribution, sales and customer feedback which they can leverage to drive successful business decisions.

Coca Cola has been investing extensively in research and development, especially in AI, to better leverage the mountain of data it collects from customers all around the world. This initiative has helped them better understand consumer trends in terms of price, flavors, packaging, and consumer’ preference for healthier options in certain regions.

With 35 million Twitter followers and a whopping 105 million Facebook fans, Coca-Cola benefits from its social media data. Using AI-powered image-recognition technology, they can track when photographs of its drinks are posted online. This data, paired with the power of BI, gives the company important insights into who is drinking their beverages, where they are and why they mention the brand online. The information helps serve consumers more targeted advertising, which is four times more likely than a regular ad to result in a click.

Coca Cola is increasingly betting on BI, data analytics and AI to drive its strategic business decisions. From its innovative free style fountain machine to finding new ways to engage with customers, Coca Cola is well-equipped to remain at the top of the competition in the future. In a new digital world that is increasingly dynamic, with changing customer behavior, Coca Cola is relying on Big Data to gain and maintain their competitive advantage.

4) American Express GBT

The American Express Global Business Travel company, popularly known as Amex GBT, is an American multinational travel and meetings programs management corporation which operates in over 120 countries and has over 14,000 employees.

Challenges:

Scalability – Creating a single portal for around 945 separate data files from internal and customer systems using the current BI tool would require over 6 months to complete. The earlier tool was used for internal purposes and scaling the solution to such a large population while keeping the costs optimum was a major challenge

Performance – Their existing system had limitations shifting to Cloud. The amount of time and manual effort required was immense

Data Governance – Maintaining user data security and privacy was of utmost importance for Amex GBT

The company was looking to protect and increase its market share by differentiating its core services and was seeking a resource to manage and drive their online travel program capabilities forward. Amex GBT decided to make a strategic investment in creating smart analytics around their booking software.

The solution equipped users to view their travel ROI by categorizing it into three categories cost, time and value. Each category has individual KPIs that are measured to evaluate the performance of a travel plan.

Reducing travel expenses by 30%

Time to Value – Initially it took a week for new users to be on-boarded onto the platform. With Premier Insights that time had now been reduced to a single day and the process had become much simpler and more effective.

Savings on Spends – The product notifies users of any available booking offers that can help them save on their expenditure. It recommends users of possible saving potential such as flight timings, date of the booking, date of travel, etc.

Adoption – Ease of use of the product, quick scale-up, real-time implementation of reports, and interactive dashboards of Premier Insights increased the global online adoption for Amex GBT

5) Airline Solutions Company: BI Accelerates Business Insights

Airline Solutions provides booking tools, revenue management, web, and mobile itinerary tools, as well as other technology, for airlines, hotels and other companies in the travel industry.

Challenge: The travel industry is remarkably dynamic and fast paced. And the airline solution provider’s clients needed advanced tools that could provide real-time data on customer behavior and actions.

They developed an enterprise travel data warehouse (ETDW) to hold its enormous amounts of data. The executive dashboards provide near real-time insights in user-friendly environments with a 360-degree overview of business health, reservations, operational performance and ticketing.

Results: The scalable infrastructure, graphic user interface, data aggregation and ability to work collaboratively have led to more revenue and increased client satisfaction.

6) A specialty US Retail Provider: Leveraging prescriptive analytics

Challenge/Objective: A specialty US Retail provider wanted to modernize its data platform which could help the business make real-time decisions while also leveraging prescriptive analytics. They wanted to discover true value of data being generated from its multiple systems and understand the patterns (both known and unknown) of sales, operations, and omni-channel retail performance.

We helped build a modern data solution that consolidated their data in a data lake and data warehouse, making it easier to extract the value in real-time. We integrated our solution with their OMS, CRM, Google Analytics, Salesforce, and inventory management system. The data was modeled in such a way that it could be fed into Machine Learning algorithms; so that we can leverage this easily in the future.

The customer had visibility into their data from day 1, which is something they had been wanting for some time. In addition to this, they were able to build more reports, dashboards, and charts to understand and interpret the data. In some cases, they were able to get real-time visibility and analysis on instore purchases based on geography!

7) Logistics startup with an objective to become the “Uber of the Trucking Sector” with the help of data analytics

Challenge: A startup specializing in analyzing vehicle and/or driver performance by collecting data from sensors within the vehicle (a.k.a. vehicle telemetry) and Order patterns with an objective to become the “Uber of the Trucking Sector”

Solution: We developed a customized backend of the client’s trucking platform so that they could monetize empty return trips of transporters by creating a marketplace for them. The approach used a combination of AWS Data Lake, AWS microservices, machine learning and analytics.

• Reduced fuel costs
• Optimized Reloads
• More accurate driver / truck schedule planning
• Smarter Routing
• Fewer empty return trips
• Deeper analysis of driver patterns, breaks, routes, etc.

8) Challenge/Objective: A niche segment customer competing against market behemoths looking to become a “Niche Segment Leader”

Solution: We developed a customized analytics platform that can ingest CRM, OMS, Ecommerce, and Inventory data and produce real time and batch driven analytics and AI platform. The approach used a combination of AWS microservices, machine learning and analytics.

• Reduce Customer Churn
• Optimized Order Fulfillment
• More accurate demand schedule planning
• Improve Product Recommendation
• Improved Last Mile Delivery

What are business analytics?

Business analytics is the use of data to make better business decisions. It involves gathering and examining data to find trends and patterns that can improve a company’s performance.

With user analytics, businesses can learn about what their customers like and how they behave. This approach helps companies make smart decisions, improve how they work, and get better results.

Why is it important to track customer behavior analytics?

Tracking customer behavior analytics is essential for business analytics for several reasons:

• Optimize marketing campaigns based on customer preferences : By understanding what your customers like and dislike, you can tailor your marketing campaigns to match their interests. This makes your marketing efforts more effective and engaging , leading to better results.
• Identify friction points : Analyzing user behavior can help you spot areas where customers face difficulties. Addressing these issues can make the user experience smoother and more enjoyable.
• Increase customer satisfaction and loyalty : Using data to understand and meet your customers’ needs makes them happier and more likely to stick with your brand. Satisfied customers are more loyal and can become advocates for your business.

What are the four types of business analytics?

Business analytics can be divided into four main types. Each serves a unique purpose in helping you analyze data to improve performance.

A business analyst plays a role in leveraging these analytics to drive success:

• Descriptive analytics : This type of analytics examines historical data to understand past trends and performance. By analyzing key performance indicators (KPIs), business analysts can identify patterns that inform future strategies. Descriptive analytics helps you make sense of past events for future planning and decision-making .
• Diagnostic analytics : This type of analytics investigates the reasons behind past outcomes. By drilling into the data, business analysts can uncover the root causes of specific results to understand why certain things happened. Diagnostic analytics provides deeper insights into the factors that influenced past performance.
• Predictive analytics : Predictive analytics : This type uses models to forecast future trends and behaviors. Using machine learning and historical data, predictive analytics can help businesses predict future events. This allows them to prepare and plan.
• Prescriptive analytics : This type provides recommendations for decision-making to achieve desired outcomes. By analyzing raw data and predicting future trends, prescriptive analytics offers actionable advice on the best steps to meet business goals. Business analysts use these recommendations to guide organizations in making informed decisions.

How to leverage customer data for actionable insights?

Research: Using AI at Work Makes Us Lonelier and Less Healthy

• David De Cremer
• Joel Koopman

Employees who use AI as a core part of their jobs report feeling more isolated, drinking more, and sleeping less than employees who don’t.

The promise of AI is alluring — optimized productivity, lightning-fast data analysis, and freedom from mundane tasks — and both companies and workers alike are fascinated (and more than a little dumbfounded) by how these tools allow them to do more and better work faster than ever before. Yet in fervor to keep pace with competitors and reap the efficiency gains associated with deploying AI, many organizations have lost sight of their most important asset: the humans whose jobs are being fragmented into tasks that are increasingly becoming automated. Across four studies, employees who use it as a core part of their jobs reported feeling lonelier, drinking more, and suffering from insomnia more than employees who don’t.

Imagine this: Jia, a marketing analyst, arrives at work, logs into her computer, and is greeted by an AI assistant that has already sorted through her emails, prioritized her tasks for the day, and generated first drafts of reports that used to take hours to write. Jia (like everyone who has spent time working with these tools) marvels at how much time she can save by using AI. Inspired by the efficiency-enhancing effects of AI, Jia feels that she can be so much more productive than before. As a result, she gets focused on completing as many tasks as possible in conjunction with her AI assistant.

After Supreme Court ruling, judge considers Trump's immunity claim in classified docs case

Donald Trump is seeking to build on his Supreme Court victory, which provided immunity from criminal prosecution for his official acts as president, by asking judges in his federal classified documents case and in his New York hush money conviction to throw out all of those charges.

U.S. District Judge Aileen Cannon postponed deadlines Saturday to debate evidence in the classified documents case and instead asked for written arguments about Trump’s immunity in the next two weeks.

Trump’s lawyers asked Cannon on Friday to halt all action in the classified documents case until she rules whether the charges are valid.

New York Judge Juan Merchan postponed sentencing Trump for his hush-money conviction of 34 counts of falsifying business records, which had been scheduled for Thursday, until September.

When the Supreme Court formally returns the election-interference case to U.S. District Judge Tanya Chutkan, she must weigh which charges are still valid to prosecute.

Neither Justice Department special counsel Jack Smith nor Manhattan District Attorney Alvin Bragg has responded to the Supreme Court’s decision yet.

Trump’s lawyers, Todd Blanche and Christopher Kise, have argued the high court’s ruling means each of the judges will have to determine which conduct is official or unofficial – and not use any official conduct as evidence for charges against unofficial conduct.

Here is where the cases stand:

Supreme Court orders 'close analysis' of whether Trump conduct was unofficial

The reason for uncertainty about criminal charges against Trump is because no former president has ever been charged before and the Supreme Court hadn’t ruled on whether they could be.

Until July 1. That’s when Chief Justice John Roberts wrote for a 6-3 majority that former presidents can’t be tried for their official acts, but could potentially be charged for unofficial acts.

The ruling said presidents discussing policy with executive agencies can’t even be questioned about their motives. This ruled out charges involving Trump urging his acting attorney general to pursue allegations of election fraud with officials in swing states.

But the ruling left open the possibility of charges dealing with Trump’s recruitment of fake presidential electors to support him in states President Joe Biden won. Roberts wrote that determining whether Trump's pressure on then-Vice President Mike Pence "requires a close analysis of the indictment’s extensive and interrelated allegations."

“The President is not above the law,” Roberts wrote. “But under our system of separated powers, the President may not be prosecuted for exercising his core constitutional powers, and he is entitled to at least presumptive immunity from prosecution for his official acts."

Trial judges must now determine whether Trump’s conduct for the various charges was official or unofficial.

Judge postpones filings in classified documents case to study Trump's immunity claim

Trump was charged with retaining national defense records and conspiring to hide them from government authorities until FBI agents seized them during a search of Mar-a-Lago, his Florida estate, in August 2022.

Prosecutors have noted the entire case involves conduct after Trump left the White House in January 2021. Smith's team office said Trump did not have legal authority to designate secret national security documents as personal records and send them to his private home. But Trump’s lawyers have argued his decision to ship the documents to Mar-a-Lago was an official act.

In an order Saturday, Cannon scrapped a Monday deadline for Trump to disclose his experts and Wednesday deadlines for prosecutors and defense lawyers to share more evidence in the case.

Instead, Cannon set a deadline July 18 for Smith to respond to Trump’s request for immunity. Trump will have until July 21 to respond.

Cannon hasn’t set a date for a hearing, but said she could still collect more evidence.

Trump’s lawyers want Cannon to only move forward on two issues in the case: Smith's request for a gag order preventing Trump from making comments that could incite threats against FBI agents working the case, and whether Smith was properly appointed to his job as special counsel.

In the Supreme Court’s ruling on immunity, Justice Clarence Thomas, wrote  a concurrence  questioning Smith's appointment, even though that wasn't at issue in the case and many special counsels have been previously appointed under similar circumstances.

Judge in federal election interference must also determine unofficial conduct

The Supreme Court hasn’t formally returned Trump’s election-interference case to Chutkan, under what is called a “mandate,” which might not happen until Aug. 2.

“The judgment or mandate of this Court will not issue for at least thirty-two days,” Supreme Court clerk Scott Harris wrote July 1 to the D.C. Circuit Court of Appeals.

Chutkan will have to review which charges – if any – can go to trial once she gets the case back.

New York sentencing postponed because of potential immunity

Merchan previously postponed sentencing Trump in the hush-money case, which had been scheduled Thursday, until Sept. 18.

But that’s only if necessary. Merchan plans to decide Sept. 6 whether Trump is immune from the charges, even though his case involves state charges and the Supreme Court was reviewing federal charges.

Trump was convicted May 30 of falsifying records to hide his reimbursement to private lawyer Michael Cohen, who paid $130,000 to silence porn actress Stormy Daniels about alleged sex with Trump before the 2016 election.

The financial arrangements between Cohen and Daniels happened before Trump was elected president. But his series of 11 payments to Cohen – through his private company – happened the first year of his presidency.

Merchan previously ruled that Trump filed an immunity argument in the case too late to be considered.

The state of EV charging in America: Harvard research shows chargers 78% reliable and pricing like the ‘Wild West’

Featuring Omar Asensio . By Barbara DeLollis and Glen Justice on June 26, 2024 .

BiGS Actionable Intelligence:

BOSTON — New data-driven research led by a Harvard Business School fellow reveals a significant obstacle to increasing electric vehicle (EV) sales and decreasing carbon emissions in the United States: owners’ deep frustration with the state of charging infrastructure, including unreliability, erratic pricing, and lack of charging locations.

The research proves that frustration extends beyond “range anxiety,” the common fear that EV batteries won't maintain enough charge to reach a destination. Current EV drivers don’t see that as a dominant issue. Instead, many have "charge anxiety," a fear about keeping an EV powered and moving, according to scholar Omar Asensio, the climate fellow at HBS’s Institute for the Study of Business in Global Society (BiGS) who led the study.

Asensio’s research is based on a first-ever examination of more than 1 million charging station reviews by EV drivers across North America, Europe, and Asia written over 10 years. In their reviews, these drivers described how they regularly encounter broken and malfunctioning chargers, erratic and secretive pricing, and even “charging deserts” — entire counties in states such as Washington and Virginia that don’t have a single public charger and that have even lost previously available chargers. EV drivers also routinely watch gas-engine vehicle drivers steal parking spots reserved for EV charging.

Asensio said that listening to the current drivers — owners rather than potential buyers — provides a new window on the state of America’s charging system because drivers are incredibly candid about their experiences.

“It’s different than what any one company or network would want you to believe,” said Asensio, who is also an associate professor at the Georgia Institute of Technology . He added that most charging providers don’t share their data and have few regulatory incentives to do so.

Research: EV chargers less reliable than gas pumps

One of the study’s main findings, discovered using customized artificial intelligence (AI) models trained on EV review data, is that charging stations in the U.S. have an average reliability score of only 78%, meaning that about one in five don’t work. They are, on average, less reliable than regular gas stations, Asensio said. “Imagine if you go to a traditional gas station and two out of 10 times the pumps are out of order,” he said. “Consumers would revolt.”

Elizabeth Bruce, director, Microsoft Innovation and Society, said, "This project is a great example of how increasing access to emerging AI technologies enables researchers to better understand how we can build a more sustainable and equitable society.”

Asensio’s research is timely as U.S. policymakers, entrepreneurs, automakers such as General Motors and Tesla , and others grapple with how to develop the nation’s charging network, who should finance it, and who should maintain it. Because charging influences vehicle sales and the ability to meet emissions targets, it’s a serious question. EV sales have climbed, topping 1 million in 2023, but concerns over batteries and charging could slow that growth.

Today, there are more than 64,000 public EV charging stations in the U.S., according to the U.S. Department of Energy's Alternative Fuels Data Center. Experts say that the nation needs many times more to make a smooth, sustainable, and equitable transition away from gas-powered vehicles — and to minimize the anxiety surrounding EVs.

“I couldn’t even convince my mother to buy an EV recently,” Asensio said. “Her decision wasn’t about the price. She said charging isn’t convenient enough yet to justify learning an entirely new way of driving.”

Reviews give voice to 1 million drivers

An economist and engineer by training, Asensio has been studying EV infrastructure since its infancy in 2010. At that time, the consensus among experts was that the private sector would finance a flourishing charging network, Asensio said. But that didn’t happen at the scale expected, which sparked his curiosity about how the charging market would emerge at points of interest rather than only near highways.

To get answers, Asensio focused on consumer reviews “because they offer objective, unsolicited evidence of peoples’ experience,” he said.

The smartphone apps that EV drivers use to pay for charging sessions allow them to review each station for factors such as functionality and pricing in real-time, much like consumers do on Yelp or Amazon. Asensio and his team, supported by Microsoft and National Science Foundation awards, spent years building models and training AI tools to extract insights and make predictions from drivers leaving these reviews in more than 72 languages.

Until now, this type of data hasn’t existed anywhere, leaving consumers, policymakers, and business leaders — including auto industry executives — in the dark.

Research reveals five facts about EV life

Here are some of the top findings from Asensio’s research about public EV charging stations:

Reliability problems. EV drivers often find broken equipment, making charging unreliable at best and simply not as easy as the old way of topping off a tank of gas. The reason? “No one’s maintaining these stations,” Asensio said. Entrepreneurs are already stepping in with a solution. For example, at Harvard Business School’s climate conference in April 2023, ChargerHelp! Co-founder Evette Ellis explained that her Los Angeles-based technology startup trains people to operate and maintain public charging stations. But until quality control improves nationwide, drivers will likely continue to encounter problems.

Driver clashes. One consumer complaint that surprised Asensio was a mysterious gripe from drivers about “getting ICE’d.” The researchers didn’t know what it meant, so they did some digging and discovered that ICE stands for “internal combustion engine.” EV drivers adopted the term to grouse about gas-fueled car drivers stealing their public EV charger spots for parking.

Price confusion. Drivers are vexed by the pricing they encounter at public charging stations, which are owned by a mix of providers, follow different pricing models, and do not regularly disclose pricing information. The result is often surprises on the road. As one reviewer wrote, “$21.65 to charge!!!!!!! Holy moly!!!! Don’t come here unless you are desperate!!”

Equity questions. Public charging stations are not equally distributed across the U.S., concentrated more heavily in large population centers and wealthy communities and less so in rural areas and smaller cities. The result is that drivers have disparate experiences, well-served in some areas and starved in others. Some parts of the country have become “charging deserts,” with no station at all.

Commercial questions. Commercial drivers in many areas can’t find enough public EV charging stations to reliably charge their cars. Here too, drivers are having very different experiences, well-supplied in some areas and not in others.

‘Wild West’ pricing is a major pain point

The research shows that EV drivers are dissatisfied with EV charging station pricing models, likening the situation to the “Wild West.” Indeed, vehicle charging is both unregulated and non-transparent.

Pricing can vary substantially by facility, level of demand, time of day, and other factors, including the type of charger available. A 45-minute fast charger may have one price, while a traditional charger that takes 3 to 5 hours may have another. Pricing can also change by the hour, based on market conditions.

Unlike traditional gas stations, which often display fuel prices on lighted signs, EV stations rarely advertise what charging will cost. Drivers often arrive without any information on what to expect or how to make comparisons, because there’s no reliable way for consumers to find the most cost-effective places to charge. “The government has a source that lists all locations, but not in real-time,” Asensio said. “You might need five different apps to figure it out.”

The driver reviews in Asensio’s data reflect the irritation caused by the current system. “People are getting frustrated because they don’t feel like they’re getting their money’s worth,” he said.

Why is the charging network so opaque? Research conducted by Asensio and his colleagues in 2021 found that charging station hosts, in the absence of regulation, have no incentive to share data — and they don’t. Station hosts are typically privately owned, highly decentralized, not well-monitored, and have highly varied patterns of demand and pricing.

The lack of transparency prevents researchers — and journalists — from investigating trends. In stark contrast to headlines trumpeting the ups and downs of gas prices, news organizations are not reporting on differential pricing among EV charging stations.

‘Charging deserts’ emerge

With municipal, state, and federal governments all pushing to increase the number of electric vehicles on the road and decrease carbon emissions, experts agree that America will need more charging stations — a lot more.

Looking only at Level 2 chargers, which top off an EV battery in 3 to 5 hours and are the most common type, S&P Global Mobility estimates a need for 1.2 million nationwide by 2027 and almost twice that by 2030. That’s in addition to in-home chargers.

Of course, that assumes robust growth in EV sales. “The transition to a vehicle market dominated by electric vehicles (EVs) will take years to fully develop, but it has begun,” said Ian McIlravey, an analyst at S&P. “With the transition comes a need to evolve the public vehicle charging network, and today's charging infrastructure is insufficient to support a drastic increase in the number of EVs in operation.”

Making matters more difficult, the chargers that do exist are not evenly distributed. Predictably, the places with the most public chargers installed are those with the highest number of registered electric vehicles, including states like California, Florida, and Texas. Yet, even as the federal government invests billions in new charging stations, many of them along major transportation corridors, places are left behind.

Asensio’s research shows that small urban centers and rural areas attract fewer public charging stations, and in some cases, there are “charging deserts” with no facilities at all — and they may not be where you think.

For example, electric vehicles are popular in Washington state, which ranked fourth in number of EV registrations and sixth in number of public charging stations in 2023. Yet Ferry County , an area outside Spokane with about 7,500 residents, where the average commute is 25 minutes and the median income is about $46,000, had only one charging station for several years. And now there are none.

Similarly, Virginia ranked 11th in EV registrations and 13th in public chargers in 2023. There, researchers found Wise County, an area outside Roanoke and Knoxville, Tennessee, with about 3,500 residents and a median income of almost $45,000. The county has an average commute time of 22 minutes, but there are no public charging stations available.

EV charging presents a classic “chicken and egg” situation, begging the question of whether cars or charging facilities must come first. However, a lack of public charging in areas like Ferry County and Wise County makes electric vehicle adoption difficult.

As American drivers debate whether to swap their gas-powered vehicles for EVs and lower emissions, Asensio said research should play a larger role. Policymakers, auto manufacturers, entrepreneurs, and investors need more and better data to build infrastructure where it’s needed, provide reliable charging, and facilitate EV sales.

“How [else] can we make effective decisions about the economics of EVs?” Asensio said.

General Motors: ‘Anxiety around EV charging’

Omar Vargas, head of public policy at General Motors, emphasized the importance of public EV charging infrastructure to driving EV adoption during an interview with The BiGS Fix at one of BiGS’ business leadership roundtables in Northern Virginia.

“We're looking at what are the best places to install an EV charging station for a community,” Vargas said. “The anxiety around EV charging is an inhibitor to EV adoption.”

Beyond the public investment in rolling out charging infrastructure, GM (whose brands include Chevrolet and Cadillac) has committed $750 million in private capital to the development of EV charging stations. It is partnering with car dealerships and other companies. For instance, GM is testing charging stations at Flying J rest stops.

GM, which reported full-year revenue of $171.8 billion for 2023 , also is joining community partnership efforts that are being formed to secure federal dollars through state and local governments. “We're helping that kind of planning, and we're pretty confident that in the next couple of years, we're going to have a vigorous EV charging network in the United States,” Vargas said.
