The need for organizations to adapt nimbly in a fast-paced global society is a given. But ask any education leader or business person how to do that in a way that truly drives the organization forward and one may get silence--or worse, a weary look that bespeaks a grievous experience. Leaders know all too well that the gap between a new idea and its successful adoption can be enormous. John Kotter, the Konosuke Matsushita professor of leadership emeritus at Harvard Business School and author of some 15 books on leadership and change, is particularly familiar with the problem. Figuring out how to bridge that chasm in a way that transforms an organization's daily dealings has been his decades-long passion. Arguably the world's foremost student of how organizations can shed old habits and create new ways of thinking, he has seen firsthand the costs of badly conceived change--from not being able to reach an important goal to alienating or burning out staff. And he is determined to share some corrective measures with every member of an organization--reaching beyond those who sit at the top to include those who don't attend business seminars or browse the business shelves in bookstores.
