John Adair is one of the most important and influential figures in the world of leadership thought and practice. More than a million people have been trained using Adair concepts such as action-centred leadership. He ranks with the likes of Warren Bennis in terms of both his influence and the depth and breadth of his thought. This book shows the depth of that influence in fields as diverse as leadership in the church, the army, higher education and business, in many parts of the world, and offers fresh and original perspectives on Adair's ideas. The authors reach beyond the historic legacy of these ideas, making proposals for improving leadership development and offering insightful warnings about current trends and fads. Anyone convinced that leadership is crucial to improved performance, but who is suspicious of 'quick fix' approaches, should read this book for both understanding and practical advice.
