  16. 19. What makes Wal-Mart successful ?
  17. 20. Wal Marts Communication Network <ul><li>Cross Docking relies on continuous communication between Wal Mart’s suppliers, distribution centers, and every point of sale system in each store. </li></ul><ul><li>This enables orders to flow in, get packaged and then shipped. </li></ul>
  18. 21. How does Wal-Mart do this? <ul><li>Wal Mart operates their own satellite network. </li></ul><ul><li>Wal Mart’s satellite network sends the point of sale (POS) data directly to 4000 vendors </li></ul>
  19. 22. Inventory Management The primary purpose to buffer against any uncertainty that might exist in the supply chain. Since holding of inventories can cost anywhere between 20 to 40 percent of their value, their efficient management is critical in supply chain operations. These include deployment strategies (push versus pull), control policies --- the determination of the optimal levels of order quantities and reorder points, and setting safety stock levels, at each stocking location

  25. 29. What we learned so far….
  26. 30. <ul><li>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 </li></ul>
  27. 31. <ul><li>Another reason that Wal-Mart's prices are so competitive is because they buy in such large quantities that transportation from one end of the supply chain to another is not as costly for additional units. This aspect of the logistical system does not come from skill or expertise it simply comes from the sheer size of the company, but this is still a factor. 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 </li></ul>
