John Adair has transformed the understanding of how leadership works with his pioneering book Not Bosses But Leaders. Now he returns with a new title that explores in an authoritative way exactly what we know about leadership and leadership development. There is a revolution underway. We are moving - rapidly in some areas, slower in others - from management to business leadership. As the market for good leaders who can achieve results increases so-called leadership development programmes have proliferated. Many of these are old management development programmes renamed, and others are full of confusing theories and unproductive approaches. This ground-breaking new book aims to set the record straight. It looks at the body of knowledge on leadership, identifies the seven key principles of leadership development, and answers key questions on how to select, train and educate leaders at the level of team, operational and strategic leadership. A vital addition to the debate on leadership from a true expert, this book also considers the global challenge and long term issues involved.
