In the early 1980s, Springfield Remanufacturing Corporation (SRC) in Springfield, Missouri, was a near bankrupt division of International Harvester.Today it's one of the most successful and competitive companies in the United States, with a share price 3000 times what it was thirty years ago.This miracle turnaround is all down to one man, Jack Stack, and his revolutionary system of Open-Book Management, in which every employee understands the company's key figures, can act on them and has a real stake in the business.In Stack's own words: 'When employees think, act and feel like owners ... everybody wins.'As a management strategy, 'the great game of business' is so simple and effective that it's been taken up by companies from Intel to Harley Davidson.
