As the commander of the Joint Special Operations Command (JSOC), General Stanley McChrystal discarded a century of management wisdom and shifted from pursuing mechanical efficiency to embracing organic adaptability. In this book, he demonstrates how any organization can make the same transition to operate like a team of teams, where small groups combine the freedom to experiment with an unrelenting drive to share their experiences. McChrystal draws on a wealth of evidence from his military career and sources as diverse as emergency rooms in hospitals and NASA's space program to outline the existential challenge facing today's organizations and presents a compelling, effective solution.
