In 2012, a stock analyst was preparing a recommendation on what his firm, a large U.S. investment house, should do with its stake in Wal-Mart Stores, Inc.

Competitors had copied many aspects of Wal-Mart’s distribution system, including cross-docking products, eliminating storage time in warehouses, positioning stores around distribution centres, and widespread adoption of electronic data interchange (EDI), as well as ordering and shipping from suppliers.
