I read this book wanting to learn more about how to implement CMM practices (at all levels) in an organization I was joining. I was disappointed. The book is divided into two parts - 8 chapters of descriptive text, and then a slew of appendices.
The descriptive text was very high-concept pop psychology type of stuff. I really did not need to be reminded that different people learn and adopt things at different rates. Anyone who has dealt with people and change should know this. In addition the constant analogy of a dancer learning new dance steps was at times lame and forced. Right up front, the author demolishes the analogy by stating that dancers get to practice their steps before performing, but software engineers start right out with the performance.
On the positive side, the appendices in the back contain useful worksheets, presentations, and ideas that can be used by practically any organization.
I wish the author had spend less time on the pop psychology aspects, and provided more examples and checklists. Then it would have been a 5 star book for sure.
