About the Book

A capstone work for the field of organization design

Greg Kesler and Amy Kates are well-known organization design authorities who have advanced Jay Galbraith’s foundational theory connecting all design elements of an organization to its strategy. In their fifth book together, they speak directly to the organization design practitioner — with a clear, practical narrative rooted in decades of consulting, writing, and teaching experience. The Five Milestone design process — used in hundreds of companies and taught to over 5,000 practitioners — has been updated to reflect today’s disruptive business environment. The book includes an expansive practices and tools section, a playbook for both deep experts and newer practitioners.
