This seems to be more popular than "High Flyers" among the line managers I interact as evidenced by how often I see it in offices, at meetings, and generally in the field. I was first exposed to this model in 1998 and have been abel to successfully apply it in a variety of HR, TM, and Coaching projects. It focuses on six key leadership levels and the development opportunities for each:

-Managing self
-Managing others
-Managing Managers
-Functional Manager
-Business Manager
-Group Manager
-Enterprise Manager

This book is a must read for managers that are in the process of planning their own development careers or that of their team - very good

Confesso que achei abstrato demais e para mim foi difícil relacionar com minha realidade.
