I had used this book for several years in my work as a trainer, facilitator, and manager. Then, I had the pleasure to attend a workshop conducted by Roger. He lives what he teaches. While I was fortunate enough to have my company pay for the workshop, it is one of only three workshops I have ever attended that I feel like I would pay my own money to attend.
Keep this book nearby. It is THE best read on this subject out there.
In the heart of Schwarz's book are seven chapters on intervening effectively in groups. In those chapters, he advises the reader on, among other things, how to intervene, meeting management, group problem-solving, following ground rules, and dealing with emotions. He closes with wisdom on serving as a facilitator in your own organization and on the facilitative leader. His opening sections on how facilitation helps groups achieve their goals and establishing the foundation for facilitation lay the groundwork for his later chapters.
In the opening chapters, he includes two models worth mentioning. In his "group effectiveness model" (p.23), Schwarz shows how group processes (the primary concern of the facilitator) interact with group structure and organizational context to contribute to a group effectiveness. Group effectiveness is assessed through three criteria: (1) The group's services or products meet or exceed the expectations of the clients; (2) The processes and structures used to deliver services or create products enhance the group's capacity to work together; and (3) The group's experience is satisfying, not frustrating, for the group's members. In the second noteworthy model, Schwarz presents the "diagnosis-intervention cycle" (p. 68). In this cycle, there are three diagnostic steps and three intervention steps. In the diagnostic phase, the facilitator observes behavior, infers meaning and decides whether to intervene. In the intervention phase, s/he describes observations, test her/his inferences, and helps the group decide whether and how to alter behaviors. Understanding and using these models are critical for effective facilitation.
For the would-be facilitator or group leader, this book provides exactly what the subtitle promises.
That said, if you are a facilitator looking to improve your skills, combine theory and practice or simply go back to the basics of what makes some facilitators great, this is your book. Also, if you are a manager who really wants to become an effective facilitator/mentor, this is your book. But don't think that you can simply read the material and be more effective. The ideas and theory will take practice. Luckily, the book also gives many examples to make the ideas and theories practical and concrete.
As I said, I bought it to become better at selling professional facilitation. It gave me that and much more. I will keep it as an invaluable resource and make sure all of my facilitators utilize the practices described in detail.
