This book introduces executive coaches to developmental psychology and stage leadership development as a measure of coaching effectiveness. It explains how they can transform themselves and their clients by applying a holistic system stage shift with 8 drivers of transformational change.The stages within adult development/vertical learning is one of the fastest growing trends in leadership development today yet there is no "go-to" book that provides a simple outline of the stages of development in terms of executive capabilities and role levels. There is also very little available on the drivers and dynamics of later stage development and how these can be leveraged through the course of executive coaching... until now.Executive coaching remains a growing field with little in the way of proven pathways to measurable outcomes. The "Figure-8 Holistic Energy Operating System Stage Shift"is inspirational. It is a highly innovative and integrative approach to stage development that liberates the mind, spirit and heart to realise our unlimited human potential.
