The Leadership Challenge has become one of the best-selling leadership books of all time. Now, with the publication of the fourth edition of their landmark book and for the first time on audio, Jim Kouzes and Barry Posner celebrate 25 years of leadership excellence. The Leadership Challenge, the most trusted source on becoming a better leader, has been thoroughly updated and revised for a new generation of leaders living and working in a global environment. Building on the knowledge base of the previous books, this fourth edition is grounded in research and presents extensive interviews with a diverse group of leaders at all levels in a wide variety of organizations from around the world. The authors emphasize that the fundamentals of leadership are not a fad. While the context of leadership has changed dramatically, the content of leadership has endured the test of time. With scores of new case studies and a timeless and inspiring message, The Leadership Challenge is a "personal coach in a book", guiding listeners through the Five Practices of Exemplary Leadership. When leaders understand that leadership is a relationship and they begin to engage in the Five Practices (Model the Way, Inspire a Shared Vision, Challenge the Process, Enable Others to Act, and Encourage the Heart), they are better able to embark on a lifetime of success and significance.
