As view form this case and video which provide in this case study I have found that Wal-Mart as one of the best supply chain management system in retail. Wal-Mart supply chain start from the manufacture as they have B2B supply chain management. They start first of all delivering the right product at the right time to right customer at lower cost it is the best method or objective of the Wal-Mart. Wal-Mart’s Retail Link is triggered by consumer purchases in local stores by point-of-purchase cash register data. In the case of Wal-Mart, the supply chain is driven by consumer behaviour which “pulls” replacement stock from inventory.
