This is a really good resource. I seems to be in possession of just about every serious leader, L&OD, Talent, HR, and Coaching professional I come across. It is at the heart of my coaching specialty and I will continue to come back to it several times over.
It is loaded with illustrative examples (the first one involving Horst Schroeder from Kellogg's was very powerful) and first class summary tables and tools. He paints a very clear, practical and compelling list of developmental experiences for High Flyers ranging from first supervisory roles to project and assignments and turnaround situations. Also hardships as development experiences.
His flow charts are extremely helpful from a practitioner's point of view. I particularly like the one about how to translate the business strategy into an executive development system. It has the backbone to state that executives cannot accomplish what cannot be defined - excellent candor. The book also creates a clear delineation between the development and selection paradigm. I found the section on making succession planning more developmental very thought provoking. The chapter on making executive development was inspiring to me and McCall provides a compelling case for doing so.
