"Those of us who work on organization change have a wealth of resources to understand the group and system levels of the organization. With Points of Influence, Morley Segal gives us the critical third piece--a comprehensive review of personality theory against the backdrop of organization practice. Finally, there is a practical guide to the individual level of our work. It is an invaluable addition to our understanding of organization change." --June Delano, director, organization change & development, Eastman Kodak Company
