Walmart Big Data

American multinational retail giant Walmart collects 2.5 petabytes of unstructured data from 1 million customers every hour. One petabyte is equivalent to 20 million filing cabinets; worth of text or one quadrillion bytes. The data generated by Walmart every hour is equivalent to 167 times the books in America’s Library of Congress. With tons of unstructured data being generated every hour, Walmart is improving its operational efficiency by leveraging big data analytics . Walmart has created value with big data and it is no secret how Walmart became successful.

Walmart was the world’s largest retailer in 2014 in terms of revenue. Walmart makes $36 million dollars from across 4300 retail stores in US, daily and employs close to 2 million people. Walmart started making use of big data analytics much before the term  Big Data became popular in the industry. In 2012, Walmart made a move from the experiential 10 node  Hadoop cluster to a 250 node Hadoop cluster. The main objective of migrating the Hadoop clusters was to combine 10 different websites into a single website so that all the unstructured data generated is collected into a new  Hadoop  cluster. Since then, Walmart has been speeding along big data analysis to provide best-in-class e-commerce technologies with a motive to deliver pre-eminent customer experience. The main objective of leveraging big data at Walmart is to optimize the shopping experience of customers when they are in a Walmart store, or browsing the Walmart website or browsing through mobile devices when they are in motion. Big data solutions at Walmart are developed with the intent of redesigning global websites and building innovative applications to customize shopping experience for customers whilst increasing logistics efficiency.Hadoop and NOSQL technologies are used to provide internal customers with access to real-time data collected from different sources and centralized for effective use.

Walmart acquired a small startup Inkiru based in Palo Alto, California to boost its big data capabilites. Inkiru Inc. helps in targeted marketing , merchandising and fraud prevention. Inkiru's predictive technology platform pulls data from diverse sources and helps Walmart improve personalization through data analytics. The predictive analytics platform of Inkiru incorporates machine learning technologies to automatically enhance the accuracy of algorithms and can integrate with diverse external and internal data sources.

First Applications to Ride the Hadoop Data at Walmart

  • Savings Catcher –An application that alerts the customers whenever its neighbouring competitor reduces the cost of an item the customer already bought. This application then sends a gift voucher to the customer to compensate the price difference.
  • eReceipts application provides customers with the electronic copies of their purchases.
  • A mapping application at Walmart uses Hadoop to maintain the most recent maps of 1000’s of Walmart stores across the globe. These maps specify the exact location where a small bar of soap resides in the widespread Walmart store.

Mupd8- Map Update Application

To fulfil the need for a general purpose real time stream processing platform which can tackle issues like performance and scalability, Walmart developed Mupd8 for Fast Data. With Mupd8, stream processing applications could emphasize on the quality of generated data. Mupd8 does for fast data, what hadoop mapreduce computational model does for big data.

Mupd8 allows developers to write applications easily and process them using the Map Update framework (a workflow of Map and Update operators), an easy way to express streaming computation. Writing an application as a combination of customized map and update operators, big data developers can focus on the business logic of the application and let Mupd8 handle load and data distribution across various CPU cores.

For example, an application can be written to subscribe to the Twitter firehose of every tweet written; such an application can analyse the tweets to determine Twitter's most influential users, or identify suddenly prominent events as they occur. Alternatively, an application can be written to subscribe to a log of all user activity on a Web site; such an application can detect service problems users’ face as they occur, or compute suggestions for users' next steps based on up-to-the-moment activity.

“Our ability to pull data together is unmatched”- said Walmart CEO Bill Simon.

Walmart uses data mining to discover patterns in point of sales data. Data mining helps Walmart find patterns that can be used to provide product recommendations to users based on which products were bought together or which products were bought before the purchase of a particular product. Effective data mining at Walmart has increased its conversion rate of customers. A familiar example of effective data mining through association rule learning technique at Walmart is – finding that Strawberry pop-tarts sales increased by 7 times before a Hurricane. After Walmart identified this association between Hurricane and Strawberry pop-tarts through data mining, it places all the Strawberry pop-tarts at the checkouts before a hurricane. Another noted example is during Halloween, sales analysts at Walmart could look at the data in real-time and found that thought a specific cookie was popular across all walmart stores, there were 2 stores where it was not selling at all. The situation was immediately investigated and it was found that simple stocking oversight caused the cookies not being put on the shelves for sales. This issue was rectified immeadiately which prevented further loss of sales.

Walmart tracks and targets every consumer individually. Walmart has exhaustive customer data of close to 145 million Americans of which 60% of the data is of U.S adults. Walmart gathers information on what customer’s buy, where they live and what are the products they like through in-store Wi-Fi.The big data team at Walmart Labs analyses every clickable action on Walmart.com-what consumers buy in-store and online, what is trending on Twitter, local events such as San Francisco giants winning the World Series, how local weather deviations affect the buying patterns, etc. All the events are captured and analysed intelligently by big data algorithms to discern meaningful big data insights for the millions of customers to enjoy a personalized shopping experience.

Better Predictive Analytics

​ Walmart has recently modified its shipping policy for products based on big data analysis. Walmart leveraged predictive analytics and increased the minimum amount for an online order to be eligible for free shipping. According to the new shipping policy at Walmart, the minimum amount for free shipping is increased from $45 to $50 with addition of several new products to enhance the customer shopping experience.

Customized Recommendations

​ Just the manner in which Google tracks tailor made advertisements, Walmart's big data algorithms analyse credit card purchases to provide specialized recommendation to its customers based on their purchase history.

Big Data Analytics Solutions at Walmart

1)  social media big data solutions.

Social Media Data is unstructured, informal and generally ungrammatical. Analysing and mining petabytes of social media data to find out what is important and then map it to meaning products at Walmart is an arduous task.

Social Media Data driven decisions and technologies are more of a norm than an exception at Walmart. A big part of Walmart’s data driven decision are based on social media data- Facebook comments, Pinterest pins, Twitter Tweets, LinkedIn shares and so on. WalmartLabs is leveraging social medial analytics to generate retail related  big data insights.

Walmart launched a social media crowdsourcing contest that helped entrepreneurs get their products on the shelf. The contest attracted more than 5000 entries and more than 1 million votes across US. Anybody could pitch in their products and get exposure to millions of audience. The best products were declared as winners and sold at Walmart stores to be made available to millions of customers.

“Social Media Analytics is all about mining retail-related insights from social channels, a perilous and personally exciting task to us. When our team spent the 22nd of November feverishly following the social retail pulse on Black Friday, we knew the world wasn’t preparing for an apocalypse.”- said Arun Prasath, a Principal Engineer at WalmartLabs

Social genome.

Social Genome is a big data analytics solution developed by WalmartLabs that analyses millions and billions of Facebook messages, tweets, YouTube videos, blog postings and more. Through the Social Genome analytics solution, Walmart is reaching customer or friends customers who tweet or mention something about the products of Walmart to inform them about the product and provide them special discount.

The Social Genome product combines public data from the web, social media data and proprietary data like contact information, email address and customer purchasing data. This data helps Walmart better analyse the context of their users.

For example, if the Social Genome identifies that a lady frequently tweets about movies, then when she tweets something like “I love Salt”, the social genome solution of Walmart is able to understand that the lady is referring to the popular Hollywood movie Salt and not the condiment salt.

“ It is only after conquering all of these multifold challenges that meaningful recommendation can be made….Our social media analytics project operates on top of a searchable index of 60 billion social documents and helps merchants at Walmart monitor sentiments and popular interests real-time, or inquire into trends in the past. One can also see geographical variations of social sentiments and buzz levels. There are also tools that marry search trends on walmart.com, sales trends in our brick-and-mortar stores and social buzz all in one place, to help make correlations. Together, these tools provide powerful social insights.”- said Arun Prasath, Principal Engineer at WalmartLabs.

Shopycat-Gift Recommendation Engine at Walmart

If you are confused on finding the perfect gift for your friends then Walmart’s Shopycat app will help you buy the ideal gift for your friend during the holiday buying rush. Walmart’s Shopycat recommends gifts for friends based on the social data extracted from their Facebook profiles. The app also provides links to the Walmart products so that users can easily purchase the product without any hassle and strive towards creating a broader marketplace . Shopycat is a part of Walmart’s Facebook page that has close to 10 million fans.

The app also suggests friends for whom users must by gifts depending on the level of interaction with them. When people click on a suggested gift, Shopycat also tells why a particular gift was suggested. For instance, the suggestions can show that a friend has liked the product on Facebook or has commented on a wall post or has a status update related to the product.

Shopycat allows the users to message their friends mutually through Facebook and ask them if they would like to buy a gift voucher or a product.

Inventory Management at Walmart using Predictive Analytics

Predictive analytics is at the heart of supply chain process that helps Walmart reduce overstock and stay properly stocked on the most in-demand products. Suppliers to Walmart are required to use the real-time vendor inventory management system that helps them minimize the inventory for a particular product if there are no significant sales for it. This helps retailers to save funds to buy products that have greater demand and have increased probability for greater profits.

  • Improving the Store Checkout Process for Customers

Big data analytics is beign leveraged to determine the best form of checkout for a particular customer - facilitated checkout or self checkout. It is using predicitive analytics to predict the demand at specific hours and determine how many asociate would be needed at specific counters.

2)  Mobile Big Data Analytics Solutions

According to Deloitte, the mobile influenced offline sales are anticipated to reach $700 billion by end of 2016. Walmart is harnessing the power of big data to drive tools and services in order to get its mobile strategy in order.

More than half of the Walmart’s customers use Smartphones and among these 35% of the shoppers are adults which is close to 3/4 th  of its overall customer base. Mobile phone customers are extremely important to Walmart as smartphone shoppers make 4 more trips and spend 77% more in-store. Thus, mobile users account for 1/3 rd of the Walmart traffic every year and approximately 40% during holidays.

“E-commerce is closely related to mobile purchase. The world’s largest retailer will use big data to enhance the consumers shopping experience in the store.” He also added: “Our mobile strategy is both simple and audacious. We want to make mobile tools become indispensable for our customers while they are shopping in our stores and online. The  retail will improve each customers personalized experience for competition in the future, and this all will happen on the small screen in their hands,” said Gib Thomas, Senior Vice President of Mobile and Digital at Walmart

Walmart is leveraging  big data analysis to develop predictive capabilities on their mobile app. The mobile app generates a shopping list by analysing the data of what the customers and other purchase every week. Walmart’s mobile application consists of a shopping list that can tell customers the position of their wants and helps them by providing discounts to similar products on Walmart.com.

Another way in which Walmart is harnessing the power of big data analysis is by leveraging analytics in real-time- when a customer actually enters the Walmart store. The geofencing feature of Walmart’s mobile app senses whenever a user enters the Walmart store in US. The app asks the user to enter into the “Store Mode”. The store mode of the mobile app helps users to scan QE codes for special discounts and offers on products they would like to buy.

With the intent of reduce waste and increasing consumer engagement, Walmart is introducing quality carts in produce departments across its stores. Walmart has employed quality carts in across 500 stores now and are expected to be present in all 5000 US stores by end of third quarter. Walmart knows that keeping its customers in the fresh produce department is the key to customer engagement and the implementation of quality carts has attractive offerings for them.Walmart is using big data and IoT sensors to find out how long people loiter in the fresh produce department. Big data analysis has helped them find that if the fresh produce looks fresh enough then people loiter for longer and this is the secret to make customers buy more things from the Walmart stores.

Walmart repurposed 200 of its existing outlets to provide grocery pickup in 30 cities. After knowing that consumers were increasingly concerned about the freshness of food, Walmart trained personnel to evaluate the quality of produce and showed food items to the customers before packing them.  If the wrap of frozen chicken is ripped or if the mango is not ripe, an exchange can be made immediately. All that the customers need to do is tap in their order through the app. Big data analytics helped Walmart win a bright spot in terms of grocery pickup.

Walmart is in the process of creating the world’s biggest private cloud for processing 2.5 PB of data every hour. Walmart has created its own analytics hub known as Data Café in Bentonville, Arkansas headquarters. At the data café, more than 200 streams of external and internal data along with 40 PB of transactional data can be manipulated, modelled and visualized.The data cafe pulls information from 200 varied sources that include Telecom data, social media data, economic data, meteorological data , Nielsen data , gas prices and local events databases  that accounts for 200 billion rows of transactional data for just few weeks. The solution to any particular problem can be found through these varied datasets and Walmart's analytic algorithms are designed to scan through the data in microsseconds to come up with a real-time solution for a particular problem.

Walmart Big Data is increasing exponentially at a rapid pace every day and the dearth of big data talent is a major roadblock for Walmart in performing analytics. With limited number of personnel possessing required big data skills –Walmart is taking every necessary step to overcome this challenge is that it does not have to fall behind its competitors. Whenever a new team member jobs the analytics team at Walmart Labs, he/she has to take part in the analytics rotation program. During this program the candidates are required to spend some time with the different departments in the company to understand how big data analytics is being leveraged across the company.

Walmart is having a tough time finding professionals with experience in cutting edge analytics applications and working knowledge of data science  programming languages like Python and R to build machine learning models. Walmart used the hashtag #lovedata for its recruitment campaign to raise its profile amongst the growing data science community in Bentonville and Arkansas.

Mandar Thakur, senior recruiter for Walmart’s Technology division said – “The staffing supply and demand gap is always there, especially when it comes to emerging technology”. With more than 40 petabytes of data available for analysis daily at Walmart, he says that there is going to be an unprecedented demand always for people who can do data science and analytics.

The secret to successful retailing of Walmart lies in delivering the right product at the right place and at the right time. Walmart continues to climb the retailing success ladder with remarkable results by leveraging big data analysis.

Walmart is fighting the big data skills gap by crowdsourcing analytics talent. Walmart hosted a Kaggle competition in 2014 where professionals where provided with historical sales dataset from sample of stores together with related sales events, price rollbacks and clearance sales. Candidates has to develop models that showed the impact of these events on the sales across various departments. The result of the competition helped Walmart find highly skilled and competent analytics talent.

In 2015, Walmart crowd sourced analytic talent with another Kaggle competition where candidates were required to predict the impact of weather on sales of different products in the store. Walmart has been able to hire skilled talent through these competition which they would not consider even interviewing based on the resume alone.

Mandar Thakur, senior recruiter for Walmart’s Technology division said- “One for example had a very strong background in physics but no formal analytics background. He has a different skillset – and if we hadn’t gone down the Kaggle route, we wouldn’t have acquired him.”

The biggest challenge for retailers like Walmart is to make predictions with limited historical data. If Thanksgiving or New Year comes once a year, retailers like Walmart have to make strategic decisions about how the sales will impact the bottom-line during the festive season. Walmart hosted a recruiting competition where job seekers were provided with historical sales data of 45 Walmart stores from different regions. Each store has multiple departments and the candidates participating in the crowdsourcing competition were required to predict the sales for each department in the store.Walmart also has promotional markdown events for prominent holidays like Christmas, Super Bowl, Labor Day, New Year, ThanksGiving, etc. Holiday markdown events were also included in the dataset provided by Walmart to add up to the challenge as the sales for holiday seasons were evaluated 5 times higher than the sales for non- holiday weeks.

The most challenging part of the competition was to predict which departments were largely affected by the holiday markdown events and what was the level of impact they had on the sales.

  • stores.csv – This file contains data about all the 45 stores indicating the type and size of each Walmart store.
  • train.csv- This file has historical training dataset from 2010 to 2012  containing the below information-

i) The Store Number

ii) The Department Number

iii) The Week

iv) Weekly Sales of a particular department in a particular store.

v) IsHoliday to indicate if it is a holiday week or not.

  • Features.csv- This file contains additional information about each store, the department, and regional activity for the mentioned dates with details like the store number , the average temperature in the region , the cost of fuel in that region, the unemployment rate, the consumer pricing index, whether the give date/week is a special holiday week or not, data related to promotional markdowns that Walmart is running.
  • Test.csv- It is just similar to train.csv except that the weekly sales are withheld in this file and the sales predictions have to be made for every triplet of the store, department and the date.

What kind of big data and hadoop projects you can work with using Walmart Dataset?

To serve its customers better, Walmart enhances customer experiences by segmenting their store visits based on different trip types. Regardless of whether a customer is- on a last-minute run looking  for new puppy supplies or is just taking a leisurely troll down the store shopping for weekly grocery.

Classifying different trip types helps Walmart enhance customer shopping experience. Initially, Walmart’s trip types are created by combing art i.e. existing customer insights and science i.e. purchase history data. A new challenge that can be solved using the Walmart dataset is to classify customer trips to the Walmart store using only transactional dataset of the products purchased so that the segmentation process can be refined.

Walmart: Big Data analytics at the world’s biggest retailer

23 July 2021

With over 20,000 stores in 28 countries, Walmart is the largest retailer in the world. So it’s fitting then that the company is in the process of building the world’s largest private cloud, big enough to cope with 2.5 petabytes of data every hour. To make sense of all this information, Walmart has created what it calls its Data Café – a state-of-the-art analytics hub located within its Bentonville, Arkansas headquarters.

walmart big data case study

Walmart uses Big Data in practice

The Data Café allows huge volumes of internal and external data, including 40 petabytes of recent transactional data, to be rapidly modelled, manipulated and visualised. Speaking to me about the project, senior statistical analyst Naveen Peddamail said, “If you can’t get insights until you’ve analysed your sales for a week or a month, then you’ve lost sales within that time.”

Quick access to insights is therefore vital. For example, Peddamail told me about a grocery team who could not understand why sales had suddenly declined in a particular product category. By drilling into the data, they were quickly able to see that pricing miscalculations had led to the products being listed at a higher price than they should have been.

The system also provides automated alerts, so, when particular metrics fall below a set threshold in any department, the relevant team is alerted so that they can find a fast solution. In one example of this, during Halloween, sales analysts were able to see in real time that, although a particular novelty cookie was very popular in most stores, it wasn’t selling at all in two stores. The alert prompted a quick investigation, which showed that, due to a simple stocking oversight, the cookies hadn’t been put on the shelves. The store was then able to rectify the situation immediately.

The technical details

As well as 200 billion rows of transactional data (representing only the past few weeks!), the Café pulls in information from 200 sources, including meteorological data, economic data, Nielsen data, telecom data, social media data, gas prices, and local events databases. Anything within these vast and varied datasets could hold the key to the solution to a particular problem, and Walmart’s algorithms are designed to blaze through them in microseconds to come up with real-time solutions.

Ideas and insights you can steal

Clearly, Walmart has huge amounts of data at its fingertips – and the resources to tackle all that data. But what any company can borrow from Walmart’s example is their ability to react to data quickly. After all, there’s little point investing in data capabilities if your internal setup doesn’t allow you to quickly make decisions and changes based on what the data is telling you.

ii) Order Sourcing and On-Time Delivery Promise

Walmart’s eCommerce platform, Walmart.com , serves millions of customers daily. One of the most crucial aspects of online shopping is the estimated delivery date. Walmart’s data scientists have developed a sophisticated algorithm that calculates this date in real time, taking into account the distance between the customer and the nearest fulfillment center, current inventory levels, and available shipping methods .

The supply chain management system determines the optimal fulfillment center for each order, considering distance and inventory levels. It also decides on the most cost-effective shipping method, all while ensuring the promised delivery date is met.

iii) Packing Optimization: The Bin Packing Challenge

In the world of retail and eCommerce, efficient packing and shipping are paramount. Walmart has tackled the age-old problem of optimizing the packing process. When items from one or multiple orders are ready for packing, Walmart employs a cutting-edge recommender system .

This system selects the most suitable box size to contain all the ordered items with minimal in-box space wastage, all within a predefined time frame. The problem, known as the Bin Packing Problem , is a classic NP-Hard problem that challenges the skills of data scientists.

Unveiling the Power of Data Science with Walmart’s Case Studies

To truly understand the practical applications of data science in the real world, Walmart offers a fascinating case study on sales prediction. The Walmart Sales Forecasting Project delves into the use of historical sales data from 45 Walmart stores, each housing numerous departments.

The challenge is to build a predictive model that can accurately project sales for each department in each store . This case study provides insights into the complexity and precision required to meet the demands of the retail industry.

Another intriguing project awaits data science enthusiasts—the Inventory Demand Forecasting Data Science Project . The goal here is to develop a machine learning model that forecasts inventory demand with precision, drawing from historical sales data.

Walmart’s data-driven journey is a testament to the transformative power of big data and data science.

It’s a story of retail reinvention, personalization, and optimization, all powered by the remarkable ability to turn data into actionable insights.

As Walmart continues to explore the endless possibilities of data-driven retail, the future promises even more innovation and excitement in the world of shopping.

How Walmart Used Big Data in the Process of Improving Supermarket Operations – Case Study

Walmart is not only the largest retailer in the world, but it is also the largest company in the world, with over two million employees and 20,000 locations located in 28 different countries.

It should not come as a surprise that a corporation of this size would see the benefits of data analytics at an early stage in their development. In 2004, when Hurricane Sandy struck the United States, it was discovered that when data was reviewed as a whole, rather than as separate individual sets, surprising insights were revealed. This discovery was made in light of the fact that when Linda Dillman attempted to forecast the demand for emergency supplies in preparation for Hurricane Sandy, she came upon some data that surprised her. As a result of the forecast for severe weather, there was a surge in demand for strawberry Pop Tarts, in addition to flashlights and other emergency supplies. During the year 2012, while Hurricane Frances was bearing down on Florida, a considerable quantity was sent to retailers that were in the line of the hurricane.

Since then, Walmart has significantly increased the size of their division devoted to Big Data and analytics, which helps to ensure that the company stays at the forefront of their industry. In 2015, the company announced their aim to construct the world’s largest private data cloud, which would have the capability to process 2.5 petabytes of data in an hour.

What kind of problems may be solved by utilising Big Data?

Supermarkets are responsible for the daily sale of millions of products to millions of customers. It is a very competitive industry that satisfies the need of a massive population in the developed world for essential items. Markets compete with one another not just on the basis of pricing, but also on the basis of the service they provide to customers and, most crucially, on the basis of how handy their locations are. Finding a way to deliver the right things to the right people at the right time presents enormous logistical hurdles. In order to price things in a manner that is competitive, close attention to every single cent is required. Customers who learn that they cannot obtain all they require in a single, accessible location are more likely to purchase elsewhere.

Applications of Big Data

In 2011, Walmart established @WalmartLabs and their Fast Big Data Team in order to investigate and deploy new data-led initiatives across the business. This was done in response to a growing awareness of how data could be used to understand customer needs and provide them with products they wanted to buy.

As a direct result of implementing this strategy, the company’s headquarters in Bentonville, Arkansas now has a state-of-the-art analytics hub called The Data Cafe. In addition to monitoring the other 200 streams of internal and external data in real time at the Cafe’, the analytics division is able to maintain track of a staggering 40 petabytes of sales data from the weeks before.

The Senior Statistical Analyst of Walmart, Naveen Peddamail, was quoted as saying, “If you can’t obtain insights until you’ve analysed your sales for a week or a month, then you’ve lost sales inside that time.” This highlights the significance of real-time data analysis in increasing the efficiency of an organisation.

We want to get the word out to our business partners as quickly as we possibly can so that they can react and reduce the amount of time it takes for the entire process to be completed. Analytics has the ability to both anticipate and react to upcoming occurrences.

Teams from all throughout the organisation are encouraged to bring their data challenges to the Cafe’, where they can work together with the analysts to figure out a solution to the problem. In addition, the organisation has a system that monitors key performance indicators and sends out automated notifications when they reach a predetermined threshold. At this point, the teams responsible for those indicators are urged to talk with the data team about ways to make things better.

Peddamail offers a team from a grocery store as an example of a group that is seeking to determine why a generally popular item has suddenly seen a decline in sales. As soon as the data from the Cafe was in the hands of the analysts, it was obvious that the decline was due to an error in pricing that had been made. After a couple of days of realising the error, it was corrected, and business went back to its usual state.

In addition, it is possible to monitor sales in many locations in real time. Peddamail recalls that during one Halloween, analysts were monitoring the sales numbers of novelty cookies and found that in some places, the cookies were not selling at all. This caught the attention of Peddamail’s employer, who decided to investigate the situation. Because of this, the merchandising staff in the stores were notified, and they realised very quickly that they hadn’t even loaded the shelves with the products. Certainly not the most complicated algorithm, but without access to real-time data, it is difficult to implement.

The Walmart Social Genome Project is another programme that monitors conversations taking place on public social media platforms in an effort to anticipate the kinds of goods that shoppers would purchase. In addition to having their very own search engine, which is known as Polaris, and being able to analyse the search terms that customers enter on their websites, they also have a service known as Shopycat, which is designed to predict how people’s shopping habits are influenced by the shopping habits of their friends (again, using social media data).

Outcome from Investigation

According to Walmart, the amount of time it takes to get from identifying an issue in the data to suggesting a solution has been cut down to something in the neighbourhood of 20 minutes thanks to the Data Cafe’ technology. In the past, completing this task would often take between two and three weeks.

Employed Information

The Data Cafe’ is driven by a database that stores 200 billion rows of transaction data, and that’s only for the data pertaining to the most recent few weeks.

In addition to this, it compiles data from two hundred additional sources, such as reports on the weather and economy, data on telecommunications and social media platforms, statistics on gas costs, and a database of events that will take place in close proximity to Walmart stores.

Notable Particulars of the Study

The real-time transaction database that Walmart uses contains 40 petabytes’ worth of information currently. In spite of the massive magnitude of this amount of data, we are just including the transactions from the most recent weeks’ worth of data because that is where the value lies in terms of real-time analysis. For the retailer, Hadoop serves as a centralised data warehouse, containing records from its physical stores, its online branches, and its corporate offices (a distributed data storage and data management system).

The goal of the strategy is to ensure that a wide variety of users have access to the information contained inside the company’s databases. As a result, CTO Jeremy King has given the plan the name “data democracy” due to the fact that it may be utilised by any member of the organisation. After the broad adoption of the distributed Hadoop architecture in 2011, there came a time when analysts started to worry that their capacity to adequately analyse the data would be hindered by the fast expanding volume of data. As a consequence of this, a plan for “intelligently managing” the collection of data was decided upon. This plan required the establishment of a number of different systems in order to clean and organise the information prior to archiving it in a permanent location. Other technologies such as Spark and Cassandra, in addition to programming languages such as R and SAS, are utilised in the construction of analytical programmes.

Challenging Circumstances

The ambitious analytics operation that was planned presented a challenge for a quickly growing firm like Walmart because it was difficult to find the right employees with the proper talents. According to a recent poll conducted by experts at Gartner, more than half of firms believe that they do not possess the essential competence to carry out Big Data analytics. This problem is not specific to Walmart in any way.

One of the resources that Walmart utilised in its search for a solution was Kaggle, a website that hosts competitions in data science.

The users of Kaggle were given a challenge in which they were asked to predict the effect that Christmas sales and stock-clearing sales would have on the sales of a number of different products. Candidates whose models showed the greatest consistency with the retailer’s actual data were sought after to fill open positions on the data science team at Walmart. One of the people who took part in the competition and afterwards found job at Walmart is Naveen Peddamail, whose observations I have integrated into this section. Naveen is currently employed by Walmart.

All new analysts are required to participate in Walmart’s Analytics Rotation Program for training. They gain an understanding of the numerous business uses of analytics by taking part in a rotation among the various analytical teams the organisation has.

According to Mandar Thakur, a senior recruiter for Walmart’s Information Systems Operation, who shared this information with me, “The Kaggle competition created a lot of interest in Walmart and our analytics group.” The most beneficial aspect was that it demonstrated how we are making strategic use of the data that Walmart creates and stores.

Conclusion and Takeaways

Supermarkets are complex creatures that are made up of a large number of distinct subsystems that all work together to function at high speeds and are subject to ongoing change. The fact that this is the case makes them an excellent candidate for the incorporation of big data analytics into their firm.

The degree of rivalry that exists between different companies is one of the most important determinants of how successful each one is. When it comes to data-driven initiatives such as loyalty and reward programmes, Walmart has always been one step ahead of the competition. By making a full commitment to the most recent developments in real-time, responsive analytics, Walmart has demonstrated their intention to maintain their position at the forefront of the retail industry.

Walmart has demonstrated that traditional brick-and-mortar retailers can reap just as many benefits from cutting-edge Big Data research as their more high-profile online competitors, such as Amazon and Alibaba. This is the case because to Walmart’s use of this technology.

It would appear that consumers, either out of habit or out of personal preference, are still willing to get in their cars and drive to shops rather than use the more convenient options that are available to them today. These options include online shopping, in-store pickup, and grocery delivery services. Which implies there is still plenty of opportunity in the market for innovative enterprises to improve efficiency and enhance the consumer experience, and those that do so will likely find significant success in the market.

“We Need People to Lean into the Future”

  • Adi Ignatius

walmart big data case study

For years, Walmart’s unrivaled customer research capabilities helped it dominate retailing. Then along came the internet, and Walmart suddenly found itself playing catchup to e-commerce pioneers like Amazon. In 2014 the board appointed Doug McMillon as CEO and gave him an imperative: Bring Walmart into the future—without sacrificing its longtime strengths.

McMillon, who began his career unloading trucks at a neighborhood Walmart, respects tradition but is impatient for change. In this interview with HBR editor in chief Adi Ignatius, he describes the ups and downs of transforming America’s largest company. Going digital is a top priority—which is why Walmart recently paid $3 billion to acquire e-tailer Jet.com. But the company also wants to strengthen the in-store experience. “The reality,” notes McMillon, “is that customers want everything”—low prices, convenience, and seamless interactions online and in person. In this new world, all employees, including those on the sales floor, will need to be tech savvy. And the management team can no longer make strategic decisions on an annual or even quarterly basis; “strategy is happening on a much faster cycle time,” says the CEO.

A conversation with Walmart CEO Doug McMillon

For years, Walmart seemed to understand exactly what its customers wanted. It developed complicated consumer analytics and used that data, along with relentless pressure on suppliers, to become a retail powerhouse that sold practically everything at the lowest possible prices.

5 Ways Walmart Uses Big Data to Help Customers

In many industries, big data provides a way for companies to gain a better understanding of their customers and make better business decisions..

By Walmart Staff

Aug. 7, 2017

Walmart relies on big data to get a real-time view of the workflow in the pharmacy, distribution centers and throughout our stores and e-commerce.

Check out the infographic below to see how Walmart uses big data to make the company’s operations more efficient and improve the lives of customers.

5 Ways Walmart Uses Big Data

Whether it’s analyzing the transportation route for a supply chain or using data to optimize pricing, big data analytics will continue to be a key way for Walmart to enhance the customer experience.

Even though Walmart was founded in 1962, it’s on the cutting edge when it comes to transforming retail operations and customer experience by using machine learning , the Internet of Things (IoT) and Big Data . In recent years, its patent applications, position as the second largest  online retailer and investment in retail tech and innovation are just a few reasons they are among the retail leaders evolving to take advantage of tech to build their business and provide better service to their customers.

Network of physical locations and online capabilities lead to innovation

Lauren Desegur, VP of customer experience engineering at WalmartLabs said, “We’re essentially creating a bridge where we are enhancing the shopping experience through machine learning. We want to make sure there is a seamless experience between what customers do online and what they do in our stores.”

While its arch nemesis in business may be Amazon.com, Walmart has the advantage of using the best of both worlds—with over 11,000 brick-and-mortar stores and its online experience—in its laboratory to develop retail tech that catapults sales and customer satisfaction. Walmart was an  early adopter of RFID to track inventory and has a tech incubator called Store No. 8 in Silicon Valley to“incubate, invest in, and work with other startups, venture capitalists and academics to develop its own proprietary robotics, virtual and augmented reality, machine learning and artificial intelligence technology.”

Recently, Walmart launched Pick-up Towers in some of its stores that are 16 x 8-foot self-service kiosks conveniently located at the entrance to the store that retrieves online orders for customers. Customers can just scan a barcode on their online receipt and within 45 seconds the products they purchased will appear on a conveyor belt. So far, customers give these Pick-up Towers positive reviews as an improvement over the store’s traditional pickup process.

Another way Walmart hopes to improve the customer experience with new retail tech is through Scan and Go Shopping. Customers in the pharmacy and money services areas will be able to use the Walmart app for some aspects of the checkout process instead of waiting until they reach the counter and then will be able to bypass the main queue to get in and out of the store more quickly. This is a step in the direction of being able to bypass the checkout process entirely with the use of computer vision, sensors and machine learning as used at the  Amazon Go concept store. Walmart already uses machine learning to optimize the delivery routes of their associate home deliveries.

Unhappy waiting in line?

One of the new ways Walmart might impact its operations is by using facial recognition technology to identify unhappy or frustrated shoppers. As the machines learn to identify different levels of frustration through the facial expressions of those in line, it could trigger additional associates to run the checkouts and eventually could analyze trends over time in a shoppers’ purchase behavior. In 2015, Walmart did also test out this technology to try to detect and prevent theft.

Tags to monitor product consumption

What’s next? According to a  patent application Walmart filed , it seems like its next step is integrating IoT tags to products in order to monitor product usage, auto replace products as necessary and monitor expiration dates or product recalls. These sensors would rely on a variety of technology such as Bluetooth, barcodes, radio frequencies and RFID tags and would provide Walmart with an incredible amount of data including the time of day products are used to where the products are kept in the house. This data could help create personalized advertising and expand cross-selling opportunities. If you had a tag reader installed on your fridge, it could scan everything you place inside and alert you when you need to restock or when items are expired. In another example, a RFID system could monitor how many times you pick up your laundry detergent and predict how much is left. This info could be added to your shopping list and fed to Walmart data vaults to illustrate consumer behavior.

Even though patents have been filed, it remains to be seen which technology Walmart will implement and make available to all its customers. One thing does seem certain: There’s no reason to believe that Walmart will slow down its investments in machine learning, IoT and Big Data to boost its performance and enhance the customer experience anytime soon.

How Walmart makes data work for its customers

Each week, more than 240 million customers shop at Walmart (online and at its banner stores), making it the world’s largest retailer.

And these days, Walmart is relying on data to power the best shopping experience for its customers, whether they’re buying from the web, via mobile devices or at traditional brick and mortar locations, says Jaya Kolhatkar, vice president of global data for @walmartlabs.

Jaya Kolhatkar

Jaya Kolhatkar, Vice President of Global Data for @walmartlabs

At the National Retail Federation's (NRF) 2016 Big Show conference in NYC, Kolhatkar discussed how @walmartlabs created a structure around its large volume of shopping data and about the culture that enables data scientists and engineers to use data to quickly build and launch new shopping experiences to customers.

To make data work for its customers, Walmart first had to make data work for its eCommerce business. And its eCommerce business is huge. $12 billion in sales last year. 12 e-commerce websites around the globe with a constant influx of data. Walmart’s e-commerce branch alone employs more than 3,000 technologists from Silicon Valley to India, England and South America.

Kolhatkar says, “Our story is one of enormous data, and also one of huge data opportunity. Transactional data, online data, mobile data – it’s what allows us to serve our customers in new ways. But, the data is so large it would be hard to put it to work for us without having the proper underlying infrastructure.”

So how big is the data? Multiterabytes of new data are collected each day. And that is combined with petabytes of historical data. All covering millions of products and hundreds of millions of customers around the world. In addition, more than 100 million keywords are constantly analyzed to know what people near each store are saying on social media.

An infrastructure for making data work

  • Data cleansing. “First things first,” says Kolhatkar. “When you have as much customer data as we do, it is absolutely imperative to cleanse it.” But on top of making sure the data is correct and of high quality, they also make sure it is kept appropriately and anonymized. Names, phone numbers and emails are segregated. Other details are encrypted. Those steps enable them to make data available for multiple users without worrying about violating privacy issues. That’s why data cleansing is the first step.
  • People make data work.  Kolhatkar says that the second key to @walmartlabs success is people. They call it the Big Fast Data Team. The team helps @walmartlab data users – which include developers, data scientists and business analyst – use the data effectively. The Big Fast Data team acquire data, develop and operate data feeds, analysis tools and implement the infrastructure. It’s a very diverse group of people with a wide set of skills.
  • Access. According to Kolhatkar, this is what really makes the magic happen. “Big data democracy is how we like to think about it,” she says. “We don’t have a data bureaucracy or a lot of approver steps. It doesn’t take months to get access to the data. Hundreds of teams can access the anonymized data simultaneously. And that’s how we make the data work for us, so it can then work for our customers. Because making the data available is key. If you have great data, it’s of no use if you keep it locked up.”
  • Choice. Kolhatkar calls this “the not-so-secret-sauce.” @walmartlabs combines a plethora of tools from a variety of partners, vendors, open source and in-house developers. They started with an enterprise data warehouse and built an infrastructure for the data. What enables this approach to work is the use of multiple BI and analytic tools. This enables @walmartlabs to hire people with different skill sets. Whether it’s accessing a Teradata warehouse or using NoSQL, SAS and Hadoop technologies, they can bring in people with diverse talent. Using different technologies helps them go from data to prototypes to launching at scale.

Building apps for an improved customer experience

More than 240 million customers visit a brick-and-mortar Walmart store each week. So it’s not just about online shopping. “We wanted to develop mobile apps to give our in-store customers the best experience possible,” says Kolhatkar.

Twenty-two million customers actively use the Walmart app each month and it ranks among the top three retail apps in the Google and Apple app stores. The Walmart app enhances the shopping experience in Walmart stores with features that include checking in to pick up an online order at a Walmart store, refilling pharmacy prescriptions and finding an item’s store location.

An in-store mobile navigation system was developed so that customers can search for items and see exactly where they are located in the store. Another app, e-receipts helps customers eliminate the pain of keeping up with printed receipts. With real-time processing for thousands of transactions, it also helps reduce item-return fraud. Wishlist was introduced in the 2015 holiday season for customers who want to create lists of items they want or find someone else’s list.

Putting all of their customer data together is working. “People are now seeing the value of what is being generated,” says Kolhatkar. Her advice? “Figure out what data to collect and then look at areas that will deliver the most value. That’s how we’re building the next generation of e-commerce for our customers.”

Introduction

The widespread adoption of technology has ushered in a new era of data-driven decision making in various industries, and retail is no exception. With the advent of e-commerce and the rise of online shopping, retailers have access to vast amounts of data that can be leveraged to gain valuable insights and drive business growth. Walmart, the retail giant, is at the forefront of this data revolution, utilizing big data to optimize its operations and enhance its customer experience.

Big data refers to the vast amount of structured and unstructured data generated from diverse sources, such as sales transactions, customer interactions, social media, and supply chain operations. This data is characterized by its volume, velocity, and variety, making it too complex for traditional data processing methods to handle. However, with advancements in technology and data analytics, businesses can now harness the power of big data to derive actionable insights and make data-driven decisions.

Walmart, with its massive customer base and extensive supply chain network, generates an enormous amount of data on a daily basis. By strategically collecting, storing, and analyzing this data, Walmart is able to gain a competitive edge, improve operational efficiency, and deliver personalized experiences to its customers.

In this article, we will explore how Walmart collects, processes, and utilizes big data across various aspects of its operations. We will examine the data sources used by Walmart, delve into its data storage and processing capabilities, and highlight some of the key applications of big data in inventory management, supply chain optimization, customer personalization, pricing, and fraud detection.

Furthermore, we will also discuss the challenges and ethical considerations associated with the use of big data in retail, as concerns around data privacy and security continue to grow.

Overall, Walmart’s use of big data demonstrates the immense power and potential of data analytics in transforming the retail industry. By leveraging the insights derived from big data, Walmart is able to make informed business decisions, enhance customer experiences, and maintain its position as a leader in the market.

What is Big Data?

Big data refers to the vast amount of data that is generated from various sources, both structured and unstructured. It encompasses the volume, velocity, and variety of data and includes information from customer transactions, social media interactions, sensor readings, and more. The term “big data” is derived from the immense size of datasets that cannot be easily managed or processed using traditional data processing methods.

There are three key characteristics of big data :

  • Volume: Big data is characterized by the massive amount of information generated. With the proliferation of digital technologies and the interconnected world we live in, data is being created at an unprecedented rate. This includes everything from website clicks and social media posts to financial transactions and sensor readings. The sheer volume of data presents unique challenges in terms of storage, management, and analysis.
  • Velocity: The velocity of data refers to the speed at which it is generated. Real-time data is becoming increasingly important for businesses to make timely and informed decisions. With the advent of the Internet of Things (IoT) and the proliferation of connected devices, data streams in at high speeds, requiring efficient processing and analysis to extract meaningful insights.
  • Variety: Big data is not just limited to structured data, such as numbers and categories. It also includes unstructured data, such as text, images, and videos. The variety of data sources adds complexity to its analysis and requires advanced tools and techniques to derive meaningful insights.

The potential of big data lies in its ability to provide valuable insights, trends, and patterns that were previously hidden or difficult to uncover.

Facing the danger of closing stores retailers are struggling to approach the Omni channel marketing, and innovating in using online platforms and shipping processes. Location, information, assortment, delivery, and ambience are important distribution services which represent essential outputs of the retail establishments, and are considerably impacted by the technological change, the evolution of retailing on the Romanian market, where were observed the highest increases in total retail trade among EU Member States, also confirming this considerable impact. Consumers are expecting personalization, retail personalization is transformed including with the help of the artificial intelligence, and there is a real retail marketers' opportunity to drive increased levels of personalization thanks to improved tracking and attribution technologies across all the channels. Both retailers and CPG companies are being forced to leverage mobile technology to communicate with their targets throughout the customer journey, enhancing the overall customer experience, and CPG companies are committing to Omni channel retail as one of the identified imperatives. Managing the change to an Omni channel marketing approach In the last issue of this journal we underlined that retailers are under real pressure for identifying the best solutions while facing challenges through the sales cycle, struggling to have the big picture of their customers' Omni channel journey, and in this respect they have to synchronize online and physical experience to deliver on brand promise, so as to ensure the wanted seamless, personal and relevant customer experience. And as we are witnessing a terrible battle within two " giants " of retailing, two quotes come to our mind: " There is nothing more poetic and terrible than the skyscrapers' battle with the heavens that cover them (Federico Garcia Lorca); " In preparing for battle I have always found that plans are useless, but planning is indispensable " (Dwight D. Eisenhower). The retail marketplace is revolutionized today by Amazon, which completely disrupted the way that traditional retailers can think about doing business, battling the likes of Amazon for an online presence being a true challenge within the general context of adequately managing the

This article examines corporate struggles to reorganize retail environments around the data capturing and processing affordances of digital media. We argue that ongoing transformations in digital retailing reflect and extend the rise of social discrimination around what might be called 'the quantified individual'. By quantified individual, we mean the hyperfocus on the qualities of the individual person rather than on even the communities or segments relating to people. Drawing on the writings of Charles Taylor, Antonio Gramsci, and Peter Berger and Thomas Luckmann, we use the ongoing corporate refashioning of the general meaning of 'loyalty' via the discourses and technologies of retailing as an important example of how a new social imaginary takes form and instantiates social discrimination as normal. For consumers, mobile apps and social-media profiles become venues for performing loyalty and accumulating rewards. For retailers and marketers, digitalized storefronts become like factories for generating data about where individuals go, what they buy and how firms define them. The process is transforming the architecture of physical and digital retailing, and the relationship between the two, in ways that make the selling environment increasingly dynamic and mutable for the individual prospect. We argue that shorn from their 20th century role in the democratization of pricing, stores will become centers of discrimination-related stress as dueling shopper and retailer technologies reach sometimes diverging conclusions about how to encourage loyalty, whom to reward for loyalty, and how.
