WALMART SUPPLY CHAIN BEST PRACTICES | MBA CASE STUDY

Let’s take a look at Walmart Supply Chain best practices. Walmart has one of the most sophisticated and efficient supply chains in the world. It has been constantly evolving since the company was founded in 1962.

In the early days, Walmart’s supply chain was relatively simple. The company would order goods from manufacturers and then ship them directly to its stores. However, as Walmart grew, its supply chain became more complex. The company began to work with more suppliers and to move goods around the world.

In the 1980s, Walmart began to invest heavily in technology to improve its supply chain. The company implemented a computer system that allowed it to track inventory levels and forecast demand. It also began to use radio frequency identification (RFID) tags to track the movement of goods.

These investments helped Walmart to improve the efficiency of its supply chain. The company was able to reduce costs, improve accuracy, and speed up the delivery of goods to its stores.

Walmart Today

Today, Walmart’s supply chain is a global network that spans over 10,500 stores in 24 countries. The company works with over 100,000 suppliers and moves billions of products each year.

Walmart’s supply chain is still evolving. The company is constantly looking for ways to improve efficiency and sustainability. It is also investing in new technologies, such as artificial intelligence and blockchain, to further streamline its operations.

Walmart’s supply chain is a major competitive advantage. It allows the company to offer low prices and a wide selection of products to its customers. It also helps Walmart to respond quickly to changes in demand.

Here are some of the key factors that have contributed to the success of Walmart’s supply chain:

  • Centralization:  Walmart has centralized its supply chain operations. This has allowed the company to improve efficiency and coordination.
  • Technology:  Walmart has invested heavily in technology to improve its supply chain. This includes the use of RFID tags, computer systems, and big data analytics.
  • Collaboration:  Walmart works closely with its suppliers to improve the efficiency of its supply chain. This includes sharing data and working together to solve problems.
  • Sustainability:  Walmart is committed to sustainability. This is reflected in its supply chain, where the company is working to reduce waste and emissions.

Walmart’s supply chain is a complex and ever-evolving system. However, the company’s commitment to efficiency, collaboration, and sustainability has helped it to create one of the most successful supply chains in the world.

Walmart and P&G Partnering

Walmart and P&G partnered to make a breakthrough in supply chain by sharing data and collaborating on new technologies.

In the late 1980s, Walmart was struggling to keep up with demand. The company was growing rapidly, and its supply chain was not able to keep pace. P&G, on the other hand, was having difficulty getting its products onto Walmart’s shelves.

The two companies decided to partner to find a solution. They began by sharing data about inventory levels and customer demand. This allowed them to better coordinate their supply chains and ensure that the right products were in the right place at the right time.

Walmart and P&G also worked together to develop new technologies to improve their supply chain efficiency. For example, they developed a system called Continuous Replenishment Program (CRP). CRP uses real-time inventory data to automatically trigger shipments of products from P&G to Walmart stores.

This partnership has been a huge success for both companies. Walmart has been able to improve its customer service and reduce costs. P&G has been able to increase sales and improve its profitability.

Here are some of the specific benefits that Walmart and P&G have gained from their partnership:

  • Reduced inventory levels
  • Increased sales
  • Improved customer service
  • Reduced costs
  • Improved profitability

The partnership between Walmart and P&G is a model for how companies can work together to improve their supply chains. By sharing data and collaborating on new technologies, companies can create a more efficient and effective supply chain that benefits everyone involved.

Half a Century of Supply Chain Management at Wal-Mart Case Answers

1. as james neuhausen, what is your analysis of wal-mart’s supply chain management are the company’s supply chain capabilities still a source of competitive advantage why or why not.

As James Neuhausen, I think Wal-Mart’s supply chain management helps it attain various competitive advantages. According to Statista, Walmart is the largest retailer and discount store globally, with net sales of U.S. $520 billion (Statista, 2020).

As we all know, now the competition is among the supply chains rather than the main businesses. Therefore, Walmart was more focused on the supply chain from the beginning to get profits by applying its everyday low-price strategy.

For this, from the beginning, Walton tried to reduce the operating costs and investment of Walmart. Walmart’s supply chain is a strong point, and with time, it has adopted various strategic methods to improve its supply chain and follow its low-price strategy (Lu, 2018).

Moreover, the U.S. famous retailer Wal-Mart’s supply chain has helped it earn a competitive advantage in the retail market. Also, it allows them to attain their mission and vision statements.

The main reason behind Walmart’s success is the collaboration and combined efforts of the partners, suppliers, customers, and management. Along with all the stakeholders’ participation, the various supply chain factors help the company gain a competitive advantage (Mark, 2012).

Some of the leading supply chain capabilities that support Wal-Mart in gaining a competitive advantage in the retail market are:

  • Walmart made excellent and long-term relations with suppliers. Also, it made the communication process easy to improve the flow of products by reducing their inventory level. Moreover, they try to use global merchandising centers to purchase bulk items to get lower prices (Lu, 2018).
  • Initially, they removed the intermediates who helped them to purchase the items. By doing this, they have reduced some of their expenditure (Mark, 2012).
  • They are also using the vendor-management inventory to give the suppliers the responsibility to manage their products. This initiative’s advantage is that the stores would get almost full inventory after some time (Mark, 2012).
  • Walmart is also using the cross-docking strategy. By applying this strategy, there is no need to store the items in between the way. However, they directly transfer the products from one truck to another truck. When they move the products to the company’s truck to deliver to stores, they change the packaging and put the tags within 24 hours. This helps to save the cost of transportation and inventory and also to save transportation time (Lu, 2018).
  • Moreover, when they cross-docked the products, the company sent their black haul products back to the suppliers. Black hauls are unsold products. They can save some of the cost and use the backward integration method (Mark, 2012).
  • Walmart was the first company to use UPCs for transactions. After that, they invested a lot in integrated technology to improve their supply chain and inventory. For this, they have implemented the retail link, a database connected with the global satellite system. There are various benefits of this database that help forecast the demand for the manufacturers and tell the real-time sales from the cash registers (Lu, 2018).
  • They have invented radio frequency tags, which helped them to reduce the 16% out-of-stocks. These tags are readable in various places like docks, shelves, warehouses, and recycled areas (Lu, 2018).

These are some of the capabilities that help Wal-Mart to attain a competitive advantage through the supply chain.

2. How is Wal-Mart doing? How does it compare to its competitors?

Wal-Mart is the leading grocery retailer worldwide. Every year, the company is increasing its total revenue by 5.65 % compared with its competitors. However, this year, its profitability is less than its competitors by a net margin of 4.67%.

Wal-Mart’s net income has increased by 74.97%, faster than the development of its competitors, which is 51.92% (CSI Market, 2020). This shows that with the increased income, their operating costs are also rising, due to which their net profit is not that much growing.

Simultaneously, the statistics show that the profit margin has been consistent for many years, resulting in cost reduction and management.

The main reasons behind Wal-Mart’s retail business’s success are increasing online and in-store sales, comprehensive financial services, a large number of pet product buyers, a pricing strategy, a large scale of operations, and bargaining power.

These are the main factors responsible for Wal-Mart’s success instead of supply chain management. One more aspect is that there is no labor union or any union; therefore, the system and processes would never be affected due to external distractions (Pratap, 2018).

Some years before 2017, Wal-Mart faced…

What makes Walmart’s supply chain so successful?

Walmart and shipbob’s winning fulfillment combo, walmart supply chain faqs.

With a revenue of over $570 billion , Walmart continues to rank number one on Fortune’s Global 500 list. This marks their ninth consecutive year at the top position, making Walmart the largest company in the world by revenue.

Walmart’s success can be attributed to having their own supply chain to streamline fulfillment and cut down on costs. It also provides them with more control over their logistics network .

In this article, we take a closer look at the Walmart supply chain and why it continues to be so successful decades later. 

Walmart’s supply chain success can be attributed to their tactful decisions to start investing in the right initiatives, including technology and expanding their logistics network, to provide value in the ecommerce space.

Below we break down the various initiatives that has made Walmart’s supply chain successful.

Early investment in supply chain optimization

Walmart’s focus on optimization is one of the largest factors contributing to the brand’s supply chain success.

The retail giant is constantly striving to improve existing systems and processes to create an optimized and efficient supply chain to provide their customers with “everyday low prices” — one of the company’s unique (and renowned) selling points.

Among the many supply chain optimization strategies, the company places great emphasis on omnichannel — multiple channels available to its customers. Walmart’s Marketplace creates a home for thousands of retail stores with the ultimate goal to save time for the consumer. 

Walmart also provides multiple marketplace fulfillment options, such as in-store pickup, ship from store, and even digital pharmacy fulfillment. Globally, Walmart offers 7,000+ pickup locations and 5,000+ delivery locations.

Fine-tuning the supply chain management system

Walmart is constantly striving to improve their supply chain management system.

From the get-go, the company started removing links within the supply chain and purchased goods in bulk to be transported directly to their stores.

They then began working directly with manufacturers and distributors to cut out the middleman to further streamline the supply chain. 

This approach plays a key role in their supply chain success. With fewer players in the supply chain, the company can lower costs and cut back on lead times to offer quick and affordable fulfillment .

Developing strong relationships with vendors early on

Walmart’s strong relationships with vendors have played a major role in their supply chain success. They go straight to the source and identify vendors who can provide them with the best price and can meet their high-volume demands. 

Walmart establishes strategic partnerships with these vendors, guaranteeing them consistent business through long-term, high-volume purchases. In return, the company can enjoy wholesale prices, which keeps customer prices competitive throughout the years. 

To further strengthen these relationships, Walmart also establishes open communication networks with their vendors. This allows them to improve the flow of inventory within the supply chain and anticipate possible disruptions before they escalate into larger problems, such as backorders , stockouts, and delivery delays.

Outsourcing inventory control with vendor managed inventory (VMI)

Walmart has further strengthened and simplified their supply chain by implementing a vendor management inventory (VMI) model.

VMI involves suppliers managing their own inventory that’s stored in Walmart’s warehouses. With this approach, the company puts the responsibility of managing inventory in the hands of suppliers, so they can save time and money on inventory management. 

With an electronically backed VMI system, suppliers have access to Walmart’s inventory data, allowing them to keep track of real-time inventory levels and sales. This makes it easy monitor how much stock is available and how certain products are sold.

Based on this information, they can see when they need to send more inventory to Walmart and keep their stock replenished.

This simplified inventory management model results in fewer delays in replenishment and reduces stockouts. It’s particularly useful since Walmart deals with hundreds of thousands of SKUs from thousands of suppliers, which can get complicated and expensive to manage. 

By transferring some of the inventory control activities to the vendors, the company can save time and focus on tasks that need to be handled in-house.

It also means that Walmart doesn’t need to spend more on dedicated personnel to manage the inventory coming from each supplier, which results in lower costs for them. All Walmart has to do is monitor the transport of inventory from warehouses to their stores.

Capitalizing on the power of technology

As Walmart undergoes a digital transformation , they’re making extensive investments in supply chain digitization and infrastructure. These investments have contributed to the successful supply chain that we see today.

Between 2019 and 2020, 72% of Walmart’s strategic capital expenditures were attributed to supply chain transformation , which includes supply chain technologies, infrastructure, and ecommerce. During this period, the company spent more than $11 billion.

These investments have resulted in faster, more flexible fulfillment , and more accurate demand forecasting .

Walmart also uses technology in their initiative to reduce packaging waste. Packaging algorithms make it easier to find the right-size packaging for each product by accurately capturing product dimensions and other attributes. 

Additionally, Walmart has implemented an advanced warehouse management system (WMS) in their distribution centers . This more nuanced WMS supports better inventory control and labor planning to streamline their supply chain operations .

Overall, one of the largest technological investments they’ve made is in automation. Autonomous mobile robots are helping warehouse staff move pallets, while other automation tools are used for picking items or packing them inside containers. 

Walmart has also made significant investments in sortation equipment, which will automatically sort products and allocate them to the right locations within the warehouse. Robust warehouse control systems help to establish a link between these automation equipment and the WMS. 

ShipBob is an official Walmart partner and participates in Walmart’s TwoDay delivery program .

ShipBob’s fulfillment platform integrates with Walmart Marketplace to display free 2-day delivery badging and fulfills 2-day orders approved by marketplace sellers.

How Walmart Automated Supplier Negotiations

walmart supply chain case study solution

Using a chatbot allows the procurement team to focus more on strategic relationships, exceptions, and continuous improvement.

It’s an age-old problem in procurement: Corporate buyers lack the time to negotiate fully with all suppliers. Historically this has left untapped value on the table for both buyers and suppliers. To address this challenge, Walmart deployed AI-powered negotiations software with a text-based interface (i.e., a chatbot) to connect with suppliers. So far, the chatbot is negotiating and closing agreements with 68% of suppliers approached, with each side gaining something it values. This article offers four lessons to deliver results from automated procurement negotiations: move quickly to a production pilot, start with indirect spend categories with pre-approved suppliers, decide on acceptable negotiation trade-offs, and scale by extending geographies, categories, and use cases.

Walmart, like most organizations with large procurement operations, can’t possibly conduct focused negotiations with all of its 100,000-plus suppliers. As a result, around 20% of its suppliers have signed agreements with cookie-cutter terms that are often not negotiated. It’s not the optimal way to engage with these “tail-end suppliers.” But the cost of hiring more human buyers to negotiate with them would exceed any additional value.

Case Study: Supply Chain Management of Walmart

The world’s largest retailer Wal-Mart was founded by Sam Walton in the year 1962. He opened his first store in Rogers, Ark. On 31st October 1969, the company was incorporated as Wal-Mart Stores. Key success factor was the guidance of Sam. Presently they are operating in fifteen countries with more than 8,000 stores with 2.1 million employees (2009). Major features of Wal-Mart stores are its store area, cleanliness and its shelves which is filled with varieties of quality items that includes health care products, family apparels, electronic items, automotive products, hardware items, jewelry etc.

Wal-Mart is giving more emphasis for customer needs and tried to reduce cost through the effective usage of supply chain management system . In the year 2009, Fortune Magazine ranked Wal-Mart as first among other retailers in its survey. Sales were about 401 billion U.S dollars in the FY 2009. Sam Walton claims that Wal-Mart’s vision had always been to increase sales through lowering the costs through organized distribution system with the help of the Information Technology. It is said that Wal-Mart’s extreme success could be attributed to its effective supply chain management.

Wal-Mart’s efficiency in supply chain management was due to two key factors namely automated distribution center and the computerized inventory system. This brought in minimizing a lot of time the later not only reduced the checking out time but also recorded the transaction which is much needed to know envisage demand. Demand forecast is a constant issue which could be a threat when not handled properly. This is due to the fact that demand prediction is always inaccurate. Aggregation would be a remedy for this unpredictable demand.

Wal-Mart’s focus has always been to sell goods at a lower price to the customers. They ensured direct purchase form the companies bypassing the intermediaries. This by passing is one of the ways to reduce cost. Wal-Mart preferred small vendors to the big players however the vendor who provides the best price qualifies and gets the deal. This applies to the giants like P& G as well. Their practice these days had been choosing few vendors and they literally negotiate the best price the one that comes up with the best price qualifies. This does not blindly mean that they have been ruthless. Wal-Mart also work with the vendors for improving its supply chain efficiency.

Wal-Mart with its power distribution system made quite innovative changes like reducing paper work, reduced its lead time drastically, used bar codes to bill which recorded inventory levels and the access to the stock levels served as the valuable data for management. The movements of products are systematic and strategically aliened in a way that it reduces the most valuable time and cost and results in efficiency. Wal-Mart had a very effective rather responsive and flexible distribution system to transport goods from docks to stores. It educated the drives with the ethics and code of conduct which pictures their supply chain responsibility. Cross docking is one lethal weapon that was used by Wal-Mart in their SCM.

Cross Docking: Cross Docking is a method of handling goods. This happens when vendor and the company work together. This is the method of supplying the product in the right time and the said quantity. This cut down a lot of time. This also changed Wal-Mart’s way of looking things. This transitioned Wal-Mart from being a centralized management to almost decentralized system took a major turn in focus of pull strategy than a pull strategy.

Cross-docking is one of the techniques used by Wal-Mart. It means there is no unnecessary storage or little storage in between the loading and unloading of goods so that customer can enjoy the quality of the goods by first hand. Wal-Mart have logistics infrastructure which is very fast transportation system wherein the distribution centers are being serviced.   Wal-Mart assured that their drivers are capable of doing their jobs accordingly and do not cause unnecessary delays that can hamper the efficiency of the distribution operations.   To deliver it on time, the coordinators give information to the driver the expected time of arrival or delivery of the goods.

Point Of Sale: Information sharing is one of the most important things when it comes to SCM. P&G with its Pampers requested Wal-Mart to share its point of sale so that it could predict its demand more or less and work on the information to bring in efficiency. When Wal-Mart shared this information P&G could plan in advance and it with its efficient supply chain management could supply pampers to Wal-Mart on time.

Wal-Mart did not want to dedicate lot of space to pamper in its warehouse of shop store either. Instead the supply was taken care by P& G. This led the initiation of working with the vendors and coming out with huge efficiency by maintaining lower inventory and satisfying demand without stock outs. Thus point of sale sharing would be a key element for any company for its further scope of improvement and also when there is further scope of improvement there is a role for Supply chain management.

Walmart Policy and Sustainability Challenges

Oketch Michael

Global companies' primary goals are global expansion, sustainability, and considerable market. Sam Walton founded the US retail giant Walmart in 1962. It manages widespread networks of discounted retail warehouses and stores (Williams, 2019). In 2022, Walmart took first in Forbes's Top 500 Fortune companies in market capitalization (Struckell et al., 2022). It is in several nations, including the USA, Argentina, Canada, and Brazil (Williams, 2019). For an extended period, Walmart has endured criticism for its dismal employee treatment, which has been the primary reason for global complaints. This international attention has hindered its global expansion, such as the failure t penetrate the German market. Several factors, including the company's supposedly poor pricing policies and low wages, have contributed to Walmart's rising negative brand image. Despite the company's critics, economists maintain that Walmart has a net beneficial impact on the global economy because it is the largest employer worldwide, with about 2.2 million employees (Alshahari, 2021). The company should re-evaluate its policy to curb growing competition and consumer-changing behavior. Policy and operational adjustment provide a solution to Walmart achieving its sustainability goals and retaining its market share.

Walmart was established by Sam Walton and beginning as a small discount retailer in Rogers, Arkansas in 1962. This paper investigates how Walmart become popular and successful in retail business around the world and how they perform well in sales. This study found that some factors were leading to the success of Walmart. Since then, Walmart has become the most trusted retailer that creates value for business and society.

Murray Rice

This research aims to provide insight regarding Wal-Mart’s retail development strategy in its expansion across the continental United States. The study examines store location patterns and relationships between Wal-Mart’s store and distribution center locations and markets. The study shows that, although radial expansion is broadly characteristic of the dense store patterns that have been well established for Wal-Mart at the national level, expansion patterns at the regional level are consistent with a selective process based on factors other than store density. These results provide a new perspective on Wal-Mart’s expansion, providing insights of value to retail practitioners and local government. Key Words: distribution center location, location intelligence, retail chain expansion, store location, Wal-Mart.

Introduction

The report illustrates the view of the business from a consultancypoint of view. Itentails the functioning of Walmart in the markets from its imitation.Since from the initiation, underthe leadership of Sam, the company adopted the cost-leadership strategy and offered the model of “everyday low prices” in US and Canada. Such model gained immense popularity and thus raised the brandawareness which ultimatelyled to building strongbrandimage in the market.

Walmart from its inceptionfocused on its supply chain efficiency to gain competitive edge in the market. It developed the models such as stock keeping units and cross dockings to reduce inventory costand toincrease the effectiveness of business in targeted markets. Such adoption of model allowed it to penetrate markets efficiently, depending on the fundamental factor of cost leadership.

In addition, the company also incorporated technology such as point of saletechnique to managethe inventory and to locate the shelfspaceaccordingly with right running product.Although, the company has gained enough brand loyaltyandbrand equity in the market, three problems are threatening the business sustainability of Walmart.Such issues include (Emergence of new business models-convenience stores (2) Ecommerce Giants-Amazon and (3) Imitation of the supply chains strategy of Walmart by other business.

The report is hence designed to highlight those issues and outline the roles of in bringing theright outcomes for company through right and adequate number of deliverables.

Walmart Supply Chain Harvard Case Solution & Analysis

Walmart is one of the world’s largest brick and plasterretailer. Its revenue increased to $67 billion in 1993 from $16 billion in 1987. The founder of the company was Sam Walton who first opened a retail shop by the name of Ben Franklin franchise store in 1945. Around the year 1994, Walmart had around 1,953 overall stores in U.S. One of the key strategies for the Walmart distribution is it would establish its retail stores in low population rural areas where its competitor would ignore building stores.

Over the period of time, the company increased in size and pursued the market penetration strategy to capture big market share in US. Till now Walmart has 11695 stores and clubs in more than 28 countries. The company has the world’s largest revenues of $480 billion with employee base of 2.3 million. The company has substantial market share and sales revenues from the US market and accounts.

Since from the initiation of the Walmart business, the company focused on its supply chain functions to manage its cost of operations and to offer price cutting strategy products in the market. In doing so, the company focused on backward integration and forward integration as well so to have a strong control over the operation and organizational function.

Walmart in initiating its smart and well-integrated business operations opened up its own distribution centers and applied the smart supply chain management techniques such as POS and SASS management to manage the inventory.Such techniques and expertise allowed WALMART to manage the inventory cost and cost stacked up into the inventory. (Sehgal, 2014)

Tracking food for better safety

We rarely think about it, but the modern food system is a marvel. We have access to fresh produce all year round, buy exotic food from all around the world, and have more variety than our ancestors could ever dream of.

Our food is generally safe to eat. Still, occasionally it can make us sick. Last year in 2018 there were at least   18 reported outbreaks   of foodborne illnesses in the USA, including the E. coli found in romaine lettuce.

“People talk about the food supply chain,” says Frank Yiannas, former Vice President of Food Safety at Walmart. “But it is not actually a chain, it’s a complex network.” When an outbreak of a food-borne disease does happen, it can take days, if not weeks, to find its source. If investigators cannot point to a specific farm or farms, the government usually advises consumers to avoid products grown in a certain area (as   happened   with romaine lettuce from Yuma, Arizona), or even to avoid the type of product altogether. According to   Walmart , millions of bags or heads of lettuce had to be removed, and consumers lost confidence in romaine lettuce altogether. Better traceability could help save lives by allowing companies to act faster and protect the livelihoods of farmers by only discarding produce from the affected farms.

For this reason, Walmart has always been interested in enhancing transparency and traceability in the food system. Mr. Yiannas explains that the company has tried many systems and approaches to solving this problem over the years; none had brought them the kind of results they were after. When Yiannas first heard about blockchain and the idea of using it to trace food in the supply chain, he was skeptical.

Screenshot 2023-07-29 at 11.11.37 PM

From blockchain skeptic to believer

Karl Bedwell, Senior Director at Walmart Technology, explains, “Creating a (traceability) system for the entire food supply ecosystem has been a challenge for years, and no one had figured it out. We thought that blockchain technology might be a good fit for this problem, because of its focus on trust, immutability, and transparency.”

Bedwell and his team introduced Yiannas to the possibilities of blockchain technologies for enterprise solutions. Says Yiannas, “I really had an “aha” moment once I deeply understood the technology. I had been hesitant about creating yet another traceability system – the ones we had tried in the past never scaled. Now I understand that was because they were centralized databases. Blockchain, with its decentralized, shared ledger felt like it was made for the food system!”

With the business interest in blockchain technology confirmed, Walmart started working on two proof of concept (POC) projects with their technology partner IBM.

Choosing the blockchain

Walmart Technology considered several blockchain technologies but ultimately decided to go for Hyperledger Fabric.

“IBM brought Hyperledger Fabric to us. We looked into Ethereum, Burrow project and others. Ultimately, we decided to go with Hyperledger Fabric because it met most of our needs for a blockchain technology,” Bedwell said. “We felt that it best met our needs. It is an enterprise-grade blockchain technology, and it is permissioned.”

The team also found it important to work with an open-source, vendor-neutral blockchain. Since the food traceability system was meant to be used by many parties, including Walmart’s suppliers and even direct competitors, the technology ecosystem underlying it needed to be open.

Hyperledger Fabric is a blockchain framework implementation and one of the Hyperledger projects hosted by The Linux Foundation. Intended as a foundation for developing applications or solutions with a modular architecture, Hyperledger Fabric allows components, such as consensus and membership services, to be plug-and-play. Hyperledger Fabric leverages container technology to host smart contracts called “chaincode” that comprise the application logic of the system.

For mangoes in the US, the time needed to trace their provenance went from 7 days to… 2.2 seconds!

Hyperledger_CaseStudy_Walmart_Graphics_Graph3-copy-2

In October 2016, Walmart, together with its technology partner IBM, announced the two projects: one was about tracing the origin of mangos sold in Walmart’s US stores and the other aimed to trace pork sold in its China stores.

For the mango POC, Yiannas started by creating a benchmark. He bought a packet of sliced mangoes at a nearby Walmart store and asked his team to identify which farm they had come from – as fast as possible. The team started calling and emailing distributors and suppliers, and eventually had an answer almost seven days later. This was not bad by industry standards, but Walmart wanted to do much better. So together with IBM, they got to work building a blockchain-based food traceability system.

The Walmart Technology team looked at their own processes as well as those of their suppliers to design the application. Archana Sristy, Director of Engineering at Walmart, explains, “[Our team at Walmart Technology] co-led the core design and setup of the application (with IBM), as well as built the integration with the enterprise systems. We worked with GS1 (the standards authority in barcodes and labeling) to define the data attributes for upload to the blockchain. IBM wrote the chaincode.

Suppliers used new labels and uploaded their data through a web-based interface.

From POC to production, from Walmart to IBM Food Trust

Once Walmart saw that the system worked, they wanted to expand it – and not just within Walmart. Given the interconnected nature of the food system and the company’s negative experience with closed systems, Walmart wanted to make sure that this time, many players were involved. Says Yiannas, “(Walmart’s) CEO was reaching out to other food companies the next day, including other retailers!” Wal-Mart collaborated with IBM and others to set up   IBM Food Trust , involving prominent players in the food industry, like Nestle and Unilever.

The Walmart team had a positive experience working with Hyperledger. “Every question that we had, it looked like the Hyperledger community had already been working on addressing that,” says Bedwell. For example, in building a truly open system, the Walmart team worried about interoperability with other blockchain-based traceability systems. And as if in answer to their concern, Hyperledger recently   announced   its collaboration with Ethereum. He adds, “It seems that the Hyperledger community is addressing everything that enterprises would be concerned about.”

Says Yiannas, “I really had an ‘aha’ moment once I deeply understood the technology. I had been hesitant about creating yet another traceability system – the ones we had tried in the past never scaled. Now I understand that was because they were centralized databases. Blockchain, with its decentralized, shared ledger felt like it was made for the food system!”

Tips from Frank Yiannas on implementing your blockchain project

1. Let the business lead the project , not the IT department.

2. Understand the business case deeply.  Make sure that you know and can explain why blockchain is the right solution.

3.   In a large organization, you need to   bring a lot of people along.  Think about all the different departments that will be affected by the projects. Meet with these stakeholders early on and explain what you are trying to do.

4. Have your soundbite!   People don’t get inspired by technology, but by a vision. For us, it was the story of mangoes – 7 days vs. 2.2 seconds with blockchain.

5. Participate in forums   that allow you to speak to other companies who have launched similar projects successfully. It helps if you help an expert in the field who’s willing to come in and educate fellow members.

6. Start small, with a POC.  And when you’ve run your pilots and are convinced about the business value, go ahead and scale. After all, Yiannas says, “Walmart is a pretty big lab! If it can scale at Walmart, it can scale anywhere!”

Hyperledger_CaseStudy_Walmart_Graphics_Timeline2

Looking forward

Walmart now traces over 25 products from 5 different suppliers using IBM Blockchain which is built atop Hyperledger Fabric. The products include produce such as mangoes, strawberries and leafy greens; meat and poultry such as chicken and pork; dairy such as yogurt and almond milk; and even multi-ingredient products such as packaged salads and baby foods.

Yiannas says of the impact, “This solution allows us to see the whole chain in seconds! We can take a jar of baby food and see where it was manufactured and trace back all the ingredients to the farms!”

Walmart plans to roll out the system to more products and categories in the near future in cooperation with IBM Food Trust.. In fact, the company recently   announced   that it will start requiring all of its suppliers of fresh leafy greens (like salad and spinach) to trace their products using the system.

“Using the IBM Food Trust network that relies on blockchain technology, we have shown that we can reduce the amount of time it takes to track a food item from a Walmart Store back to source in seconds, as compared to days or sometimes weeks,” Walmart wrote in a   letter   to suppliers.

Beyond tracing the products’ journey, the company might start tracing other data, like sustainability.

Building Insights Into Supply Chains: A Case Study

A GRAPHIC SHOWING MULTIPLE TRUCKS ON ROADWAYS, WITH TRACKING SIGNS SUPER-IMPOSED OVER THEIR LOCATIONS.

Image: iStock.com/metamorworks

For time-sensitive or temperature-controlled cargo, most shippers will agree that high-quality, real-time tracking information is crucial. Though that technology can be expensive, the investment is easy to justify when it could mean the difference between an on-time delivery and spoiled cargo. But for general cargo — which does not have strict timeline requirements — it can be harder for shippers to justify that cost. Individualized tracking information simply isn’t as critical for those standard loads. And if shippers do decide to invest in tracking devices for general cargo, rarely is the technology advanced enough to make a sizable difference to their bottom line.

Some leaders in the shipping space argue that this view is shortsighted — and could cost companies far more than they realize. Without the data that tracking technology could provide, they believe, many shippers lose out on important insights into their general cargo — data that could significantly improve travel timelines and ultimately justify that initial cost.

Two of these leaders are Maersk, a provider of transportation and logistics services, and Tive, a global leader in supply chain and logistics visibility technology. Both organizations felt that the potential value of tracking insights into general cargo was too important to overlook. So when Erez Agmoni, global head of innovation at Maersk, and Krenar Komoni, founder and CEO of Tive, crossed paths at a supply chain event at MIT a few years back, it was no surprise that they found a common purpose.

Both Agmoni and Komoni knew that tracking technology was too costly to be used across every type of cargo. “Unless it’s valuable, perishable cargo,” says Agmoni, “nobody will want to just go and track every single container, every single shipment — especially considering a few years ago, when it was really expensive.” Agmoni and Komoni knew they needed to develop a more affordable solution that could provide data that was actually relevant to all types of general cargo shipments.

The Proof of Concept

In the years following the MIT event, Agmoni and Komoni explored alternatives that could offer the value they sought at a price point shippers would accept. The first step in their experiment was to design a proof of concept. The team at Maersk took on the task, beginning with outreach. “We went to customers, we brought them in, we started some discussions,” says Agmoni. “We looked into what could help them improve their supply chains.” Over the course of their research, customers commonly expressed frustration with transit times: They were unreliable, inaccurate, and did little to help them plan around the situation at hand. That’s when Agmoni had an idea. Instead of tracking each individual shipment — which, as customers were saying, wasn’t providing the information they actually needed — they could also track aggregated data.

The Maersk Innovation Center designed a proof of concept for a means of keeping tabs on thousands of shipments without having to view each one individually. In other words, they would track aggregated data from thousands of shipments, starting with a route from Los Angeles to Memphis. Tive, meanwhile, started building the hardware and the backend technology. Once the product was ready, Tive ensured that all of the trackers were properly installed at the warehouse in Los Angeles, and that each of them was linked to the appropriate shipment and order.

From there, Tive’s data science and data analytics teams, with input from Maersk, went to work analyzing the data from the trackers — looking at which algorithms they wanted to run on the dataset to figure out what insights they could gain. “Working together, we were able to find some really interesting things,” says Komoni. In the end, the higher-level view yielded surprising insights.

The Results

On the drive from Los Angeles to Memphis, there are two main routes from which truckers can choose: a southern route, which runs near the U.S.–Mexico border, and a northern route, which is a slightly more direct line from point A to point B. On all navigation systems, the northern route is estimated to be two hours faster than its counterpart. But when Maersk and Tive started looking at the aggregated data, they learned something that they couldn’t have known from individualized tracking information.

“When we started to look at the aggregated data,” says Agmoni, “we found out that the northern route is taking six days, plus or minus two — so four to eight days.” Though Google Maps will estimate the drive to be 32 hours, it’s expected that drivers will need to stop and rest along the way, stretching the trip out into several days. But when they looked at the presumably slower, southern route, the average driver was completing the trip in four to six days. Not only was this faster, but the driving estimate was more precise.

To understand why this was, they had to go back to the data. Using a collection of tools and graphs that they’d custom built for this purpose, Tive began to calculate the idle times along each route. “What we said is, ‘why don’t we figure out where the trucks are stopping for the longest time?’” says Komoni. “And then we mapped that out, and we saw these big red spots on areas where they’re stopping on the southern route and also where they’re stopping on the northern route.

”It quickly became clear from the data that drivers on the northern route were stopping much more frequently than on the southern route. “We couldn’t know why they’d do that,” says Agmoni, “so we had to call some of them. And we learned a very interesting thing.”

After speaking with some of the drivers, they learned that rest stops on the northern route are small and, more often than not, completely full. “It’s a very busy route,” says Agmoni. “They don’t trust that there will be space at the rest stop when they’ve reached the maximum hours of driving. So they start looking two or three stops beforehand. If there is one, they stop; if not, they’ll go to the next on the route.” On the southern route, however, the stops are more reliable. Drivers can trust that when they need to make a stop, there will be space for them to do so — allowing them to maximize the number of hours that they can drive, and shortening the total transit time altogether.“

That really helped us to change the way we route things. You can’t find this information if you follow one shipment at a time; you really need the aggregated data,” says Agmoni.

“It's great insight,” Komoni adds, “because now you finally have value that you can sell. You can justify the cost on all types of general cargo — and not just on time-sensitive, temperature-sensitive, high-value shipments.”

Maersk and Tive’s proof of concept was a clear success, allowing them to move forward in the development of their product.

The Solution

Using what they learned, Maersk has since developed a new product called Ocean + Transload, a solution for cargo transportation that improves transit time variability, reduces carbon emissions, and helps minimize detention and demurrage charges.

“It’s a replacement for the inland port solutions that carriers sell,” says Agmoni. Typically with intermodal travel, carriers see a lot of fluctuation in transit times. “The intermodal connection of international containers is not to the level of our customer expectation,” he says.

With Ocean + Transload, they can take containers and translate them into trailers by putting them back on the rail or on the road. “And of course we are adding visibility trackers to all those shipments at no extra cost — to provide our customers with a solution that first, gives them a much more precise time, and second, sends alerts way in advance when the shipment is about to arrive.” Armed with this increased visibility into their shipments, customers no longer need to follow up to receive updates on the status of their shipment. Updates come to them directly.

According to Komoni, the uniformity of the data made possible by the collaboration was a central component to the solution’s success. “I think that uniformity is the real value that allows Maersk to do aggregated analytics and understand insights for their customers. There is tremendous value in uniformity,” he says.

What started as a shared frustration at the lack of tracking information on general cargo shipments resulted in not only a successful collaboration between two companies — it also provided a much-needed advancement in tracking technology and shipping analytics that will help companies make smarter and more cost-efficient decisions across the supply chain.
