This revised edition of Peter Senges bestselling classic, The Fifth Discipline, is based on fifteen years of experience in putting the books ideas into practice. As Senge makes clear, in the long run the only sustainable competitive advantage is your organizations ability to learn faster than the competition. The leadership stories in the book demonstrate the many ways that the core ideas in The Fifth Discipline, many of which seemed radical when first published in 1990, have become deeply integrated into peoples ways of seeing the world and their managerial practices.
