This revised edition of Peter Senge's bestselling classic, The Fifth Discipline, is based on fifteen years of experience in putting the book's ideas into practice. As Senge makes clear, in the long run the only sustainable competitive advantage is your organization's 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 people's ways of seeing the world and their managerial practices. In The Fifth Discipline, Senge describes how companies can rid themselves of the learning "disabilities" that threaten their productivity and success by adopting the strategies of learning organizations–ones in which new and expansive patterns of thinking are nurtured, collective aspiration is set free, and people are continually learning how to create results they truly desire.
