Tim Cook arrived at Apple in March 1998 and inventory went from about a month to about six days. Almost nobody knows it's in Apple's own 10-K. The company disclosed days of supply in inventory as a line item: 31 days in FY1997, 6 days in FY1998, 2 days in FY1999. Inventory in dollars: $437m, $78m, $20m. This episode reconstructs how, using Apple's filings rather than the folklore and then asks the harder question: what did the doctrine actually build, and what did it cost? We cover the Cook's inheritance of Apple's operations, six moves he made in restructuring it's supply chain, balance sheet implications + cash released from these moves, and how Cook handled the various economic, regulatory, legal, and geopolitical shocks across his decades long tenure at Apple.
