"Contending that the rate of change in the market has clearly outstripped the speed at which a conventionally managed company can respond, Day makes a compelling case for first creating superior customer value, without which there can be no shareholder value. He presents a proven market-driven approach to formulating and implementing competitive strategy at the business-unit level - "in the trenches" - based upon materials that have been empirically tested and critiqued in more than 200 internal executive programs and strategic planning sessions at such companies as U.S. West, General Motors, Marriott, Kodak, and General Electric."--BOOK JACKET.
