You can think of business as a multiplayer game between the supply chains of different companies. Companies use their supply chains to lower operating expenses, offer new services and appeal to more customers. The competing supply chains of Walmart and Amazon are an example of this. In the 1990’s Walmart introduced new technologies and procedures that supercharged their supply chain and drove their growth. Now Amazon is introducing new technologies and procedures to again change how supply chains operate and supercharge Amazon’s growth.
