This extraordinary book was written by Dr. Belbin nearly 20 years ago and remains in a class by itself in providing a useful theory for building and operating effective decision-making teams. Nowhere else will the reader find a set of principles that are so soundly based on direct evaluation of competing teams, explain so much of effective and ineffective team behavior which otherwise confounds explanation, and which is so beautifully and succinctly written.
While Belbin's title suggests this book is simply about business management, the content of the book is of much wider applicability. This book is a valuable, perhaps indispensable, source for anyone involved in collaborative endeavors. The book would be useful if it merely answered the question "Why do collaborative (creative, decision-making) teams succeed or fail?" Belbin goes much further than that. He tells us how to proactively build teams that are predisposed to succeed and, equally importantly, how to adopt strategies that will lead to success on the part of teams not so fortunately constructed.
I have found this book very useful in building, and teaching the building, of software product development teams, and heartily recommend it for that purpose.
