This excellent book is targeted directly at Project Management Professionals (PMPs) but will be extremely beneficial to any project manager who is interested in agile development.
After three short chapters that introduce the general principles and activities of an agile software development project, the authors attack the meat of their subject. Each of the nine chapters of part two corresponds directly to one of the PMI's project management knowledge areas. Sliger and Broderick, each an experienced PMP, cover the changed responsibilities of the project manager transitioning to agile. A highlight of each chapter is the small table with columns for "I used to do this" and "Now I do this" that succinctly summarizes the often profound differences between traditional and agile project management.
This book is necessary reading for any project manager making the change to agile as well as for any ScrumMaster or agile coach working on a large projects. The book takes a giant stride toward dispelling the myth that the only role for project managers is to buy pizza and soda and get out of the way.
