Coaching is growing across the globe as a viable and useful intervention to help executives deal with the complexity they face day-to-day. In response to this increased demand, many coaches have presented their "model" of coaching to the world of business, and a number of these have made it into print. Few are based on a rigorous development process or have provided the reader with an insight into their development. The Author wanted to offer to the readers of our professional coaching series the opportunity to engage with a practitioner who had been through a journey of learning built on their experience, the literature and research. This book meets the need identified for a clear and rigorous account by an experienced coach of the development of their model within the scientist-practitioner framework.
