Despite the wonderful accomplishments of Drs. Blanchard and Johnson, this book was very dissappointing.
I think of it as typical consultants' babble because you will get wrapped up in intellectual theories and appraoches to the art of management, but after you put the book down you'll realize you've got nothing tangible and practical to use in your everyday life. As a management consultant once explained to me about his field, many consultants are good "Beanbag Punchers". They make an amazing change where they strike the bag, but on the opposite side nothing has really changed. I was disappointed in this book because the authors are clearly not Beanbag Punchers, but nothing about my management sytle has benfitted from this book.
Furthermore, the fictional approach of the book (I'm assuming the underlying story is fictional) is borderline condescending. Its tone is similar to the grade school books your 10-year-old reads to learn good manners.
However, the book is reasonably priced and very short reading, so you may enjoy its content based on the effort you'll expend. The theories expressed are unique and thought provoking.
Bottom line:
If you want to learn how to be a better manager, this book isn't your answer.
If you want to explore news ways to manage people, it's worth a quick read.
