Initially written in 1987, The Leadership Challenge became one of the best-selling leadership books of all time. Now, faced with the new challenges of our unpredictable global business environment, Jim Kouzes and Barry Posner, two premier leadership experts, have completely revised and updated their classic book. Building on the knowledge base of their previous books, the third 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. In this edition, the authors emphasize that the fundamentals of leadership are the same today as they were in the 1980s, and as they have probably been for centuries. While the content of leadership has not changed, the context has changed, and in some cases, changed dramatically.
