This book represents both a milestone and a celebration. It brings together in one place all the theories and models that have emerged from the work of David Clutterbuck, one of the last surviving, first pioneers of coaching and mentoring, who has significantly helped to shape the field; and is published as his 75th book at age 75. Many of the models and approaches familiar to coaches and mentors are based in David’s prolific research, writing and practice, from Systemic Talent Management, through Team Coaching from a Complex, Adaptive Systems perspective, Personal Reflective Space, to the Diversity Awareness Ladder. In bringing more than 60 of these innovations into one volume, the book provides an invaluable contribution to the practice of coaching, and puts the evolution of coaching theory into context, tracing its development over time. This book is a one-stop-shop for coach practitioners and students to get up to speed and understand these foundational models. This book will appeal to coaches and HR professionals across the world, at all levels.
