• Inventory management
![Page 17: Walmart Supply Chain Management](https://reader033.fdocuments.in/reader033/viewer/2022061423/555c37fbd8b42a0b038b4812/html5/thumbnails/17.jpg)
Wal-Mart’s Procurement
• Wal-Mart emphasized the need to reduce purchasing costs and offer the best price to the customer.
• The company directly procured from manufacturers, by avoiding all intermediaries.
• Wal-Mart finalizes a purchase deal only when it is fully confident that the products being bought is not available else where at a lower price.
![Page 18: Walmart Supply Chain Management](https://reader033.fdocuments.in/reader033/viewer/2022061423/555c37fbd8b42a0b038b4812/html5/thumbnails/18.jpg)
Electronic Data Interchange
• Increased productivity

Distribution Management of Wal-Mart
• Bull whip effect
• Vendor managed inventory
![Page 20: Walmart Supply Chain Management](https://reader033.fdocuments.in/reader033/viewer/2022061423/555c37fbd8b42a0b038b4812/html5/thumbnails/20.jpg)
Bull Whip Effect
The bullwhip effect (or whiplash effect) is an observed phenomenon in forecast-driven distribution channels.
- Customer demand is rarely perfectly stable.- Businesses must forecast demand in order to properly
position inventory and other resources.
The concept first appeared in Jay Forrester's Industrial Dynamics (1961) and thus it is also known as the Forrester effect
![Page 21: Walmart Supply Chain Management](https://reader033.fdocuments.in/reader033/viewer/2022061423/555c37fbd8b42a0b038b4812/html5/thumbnails/21.jpg)
Forecasts are based on statistics, and they are rarely perfectly accurate. Companies often carry an inventory buffer called "safety stock". Moving up the supply chain from end-consumer to raw materials supplier, each supply chain participant has greater observed variation in demand and thus greater need for safety stockIn periods of rising demand, down-stream participants will increase their orders.In periods of falling demand, orders will fall or stop in order to reduce inventory.

Vendor Managed Inventory
• The vendor (supplier) manages the stock levels and availability for the customer based on safety stock levels the as per the agreed Terms & Conditions.
• Vendor Managed Inventory (VMI) is a planning and management system in which the vendor is responsible for maintaining the customer’s inventory levels.
• Manufacturers generate orders, not distributors or retailers Stocking information is accessed using EDI
• A first step towards supply chain collaboration
• Increased speed, reduced errors, and improved service

Logistics Management• An important feature of Wal-Mart’s logistics infrastructure
was its fast and responsive transportation system.
• The distribution centers were serviced by more than 7000 company owned trucks.
• Wal-Mart believed that it needed drivers who were committed and dedicated to customer service.
• The company hired only experienced drivers who had driven more than 300,000 accident-free miles, with no major traffic violation.

Cross docking
• Cross-docking means to take a finished good from the Manufacturing plant and deliver it directly to the customer with little or no handling in the process.
• In purest form this is done directly, with minimal or no warehousing.
![Page 28: Walmart Supply Chain Management](https://reader033.fdocuments.in/reader033/viewer/2022061423/555c37fbd8b42a0b038b4812/html5/thumbnails/28.jpg)

Hub and Spoke
In the early 1970s, Wal-Mart became one of the first retailing companies in the world to centralize its distribution system, pioneering the retail hub-and-spoke system.
Under the system, goods were centrally ordered, assembled at a massive warehouse, known as ‘distribution center’ (hub), from where they were dispatched to the individual stores (spoke).
![Page 30: Walmart Supply Chain Management](https://reader033.fdocuments.in/reader033/viewer/2022061423/555c37fbd8b42a0b038b4812/html5/thumbnails/30.jpg)
The hub and spoke system enabled Wal-Mart to achieve significant cost advantages by the centralized purchasing of goods in huge quantities..
And distributing them through its own logistics infrastructure to the retail stores spread across the U.S.

Wal -Marts Communication Network
• Cross Docking relies on continuous communication between Wal Mart’s suppliers, distribution centers, and every point of sale system in each store.
• This enables orders to flow in, get packaged and then shipped.
• Wal Mart operates their own satellite network.
• Wal Mart’s satellite network sends the Point Of Sale (POS) data directly to 4000 vendors
![Page 33: Walmart Supply Chain Management](https://reader033.fdocuments.in/reader033/viewer/2022061423/555c37fbd8b42a0b038b4812/html5/thumbnails/33.jpg)
Inventory ManagementWal-Mart invested heavily in IT and communication systems to effectively track sales and merchandise inventories in stores across the country.
With the rapid expansion, it was essential to have a good communication system.
Hence, Wal-Mart set up its own satellite communication system in 1983.
![Page 34: Walmart Supply Chain Management](https://reader033.fdocuments.in/reader033/viewer/2022061423/555c37fbd8b42a0b038b4812/html5/thumbnails/34.jpg)
Inventory Management(cont……)
Wal-Mart was able to reduce unproductive inventory by allowing stores to manage their own stocks, reducing pack sizes across many product categories, and timely price markdowns.
Instead of cutting the inventory across the board, Wal-Mart made full use of its IT capabilities to make more inventories available in the case of items that customers wanted most, while reducing the overall inventory levels.
![Page 35: Walmart Supply Chain Management](https://reader033.fdocuments.in/reader033/viewer/2022061423/555c37fbd8b42a0b038b4812/html5/thumbnails/35.jpg)
Inventory Management(cont……)
Employees at the stores had the “Magic Wand,” a hand-held computer which was linked to in-store terminals through a radio frequency network.
These helped them to keep track of the inventory in stores, deliveries, and backup merchandise in stock at the distribution centers.
![Page 36: Walmart Supply Chain Management](https://reader033.fdocuments.in/reader033/viewer/2022061423/555c37fbd8b42a0b038b4812/html5/thumbnails/36.jpg)
CPFR
• By the mid 1990s, Retail Link had emerged into an Internet-enabled SCM system whose functions were not confined to inventory management alone, but also covered collaborative planning, forecasting and replenishment (CPFR).
• CPFR is defined as a business practice for business partners to share forecasts and results data through the Internet, in order to reduce inventory costs while at the same time, enhancing product availability across the supply chain
![Page 37: Walmart Supply Chain Management](https://reader033.fdocuments.in/reader033/viewer/2022061423/555c37fbd8b42a0b038b4812/html5/thumbnails/37.jpg)
Though CPFR was a promising supply chain initiative aimed at a mutually beneficial collaboration between Wal-Mart and its suppliers, its actual implementation required huge investments in time and money.
A few suppliers with whom Wal-Mart tried to implement CPFR complained that a significant amount of time had to be spent on developing forecasts and analyzing sales data.
![Page 38: Walmart Supply Chain Management](https://reader033.fdocuments.in/reader033/viewer/2022061423/555c37fbd8b42a0b038b4812/html5/thumbnails/38.jpg)
Radio Frequency Identification
• In efforts to implement new technologies to reduce costs and increase the efficiency, in July 2003, Wal-Mart asked its top 100 suppliers to be RFID compliant by January, 2005.
• Wal-Mart planned to replace bar-code technology with RFID technology.
• The company believed that this replacement would reduce its supply chain management costs and enhance efficiency.
![Page 39: Walmart Supply Chain Management](https://reader033.fdocuments.in/reader033/viewer/2022061423/555c37fbd8b42a0b038b4812/html5/thumbnails/39.jpg)
• Because of the implementation of RFID, employees were no longer required to physically scan the bar codes of goods entering the stores and distribution centers, saving labor cost and time.
• Wal-Mart expected that RFID would reduce the instances of stock-outs at the stores.
• Although Wal-Mart was optimistic about the benefits of RFID, analysts felt that it would impose a heavy burden on its suppliers.
• To make themselves RFID compliant, the suppliers needed to incur an estimated $20 Million.
• Of this, an estimated %50 would be spent on integrating the system and making modifications in the supply chain software
![Page 40: Walmart Supply Chain Management](https://reader033.fdocuments.in/reader033/viewer/2022061423/555c37fbd8b42a0b038b4812/html5/thumbnails/40.jpg)
Information Technology: A Supply Chain Enabler
• Information links all aspects of supply chain
• E-business
– replacement of physical business processes with electronic ones
• Electronic data interchange (EDI)
– a computer-to-computer exchange of business documents
![Page 41: Walmart Supply Chain Management](https://reader033.fdocuments.in/reader033/viewer/2022061423/555c37fbd8b42a0b038b4812/html5/thumbnails/41.jpg)
What we learned so far….
![Page 42: Walmart Supply Chain Management](https://reader033.fdocuments.in/reader033/viewer/2022061423/555c37fbd8b42a0b038b4812/html5/thumbnails/42.jpg)
One of the keys to Wal-Mart's effective logistical system is the flexibility that it has when choosing suppliers.
When Wal-Mart negotiates with suppliers and the suppliers know that Wal-Mart will only pay the most competitive prices. This is because it is very easy for them to find another supplier of that particular material with a lower price and very few logistical problems
![Page 43: Walmart Supply Chain Management](https://reader033.fdocuments.in/reader033/viewer/2022061423/555c37fbd8b42a0b038b4812/html5/thumbnails/43.jpg)
Another reason that Wal-Mart's prices are so competitiveis because they buy in such large quantities thattransportation from one end of the supply chain to anotheris not as costly for additional units.
This aspect of the logistical system does not come fromskill or expertise it simply comes from the sheer size ofthe company, but this is still a factor.
![Page 44: Walmart Supply Chain Management](https://reader033.fdocuments.in/reader033/viewer/2022061423/555c37fbd8b42a0b038b4812/html5/thumbnails/44.jpg)
Wal-Mart buys so many supplies from different places throughout the world, that they have the luxury of using bigger trucks and using less fuel to go back and forth.
Also if by chance they have to use shipping services to transport material from one location to another, Wal-Mart will give them so much business that they will get huge discounts
