As CEO of GE for 20 years, Jack Welch built its market cap by more than $450 billion & established himself as the most admired business leader in the world. His championing of initiatives like Six Sigma quality, globalization, & e-business have helped define the modern corporation. At the same time, Welch is a gutsy boss who has forged a unique philosophy & an operating system that relies on a ''boundaryless'' sharing of ideas, an intense focus on people, & an informal, give-&-take style that makes bureaucracy the enemy. In this book, Welch gives us the people who shaped his life & the big hits & the big misses that characterized his career. Includes the story of his last year -- the process of selecting a successor & the attempt to buy Honeywell. Photos.
