expanded, updated, and more relevant than ever, this bestselling business classic by two internationally renowned management analysts describes a business system for the twenty-first century that supersedes the mass production system of ford, the financial control system of sloan, and the strategic system of welch and ge. it is based on the toyota (lean) model, which combines operational excellence with value-based strategies to produce steady growth through a wide range of economic conditions. 　　 in contrast with the crash-and-burn performance of companies trumpeted by business gurus in the 1990s, the firms profiled in lean thinking -- from tiny lantech to midsized wiremold to niche producer porsche to gigantic pratt & whitney -- have kept on keeping on, largely unnoticed, along a steady upward path through the market turbulence and crushed dreams of the early twenty-first century. meanwhile, the leader in lean thinking -- toyota -- has set its sights on leadership of the global motor vehicle industry in this decade.
