Now, faced with the new challenges of our unpredictable global business environment, Jim Kouzes, and Barry Posner--two of the country's premier leadership experts--have completely revised and updated their classic book. Building on the knowledge base of their previous books, this edition of The Leadership Challenge is grounded in extensive research and based on interviews with all kinds of leaders at all levels in public and private organizations from around the world emphasizing that the fundamentals of leadership are the same today as they were in the 1980s, and as they've probably been for centuries. In that sense, nothing's new. Leadership is not a fad. While the content of leadership has not changed, the context has-and in some cases, changed dramatically.
