The book is made of two sections. The first section is the narration of many conversations within a multi-day off-site leadership exercise, and the second section is the crystallization of lessons learnt from the exercise.
The exercise is unlike any boring corporate offsite. The participants are divided into 3 groups (elites, immigrants, and managers) with different resources and powers and left inside a gated community. The "Survivor" like setup leads to very predictable character driven behavior from participants that is unlike them in the "real" world. The tiring script of conversations and negotiations amongst the 3 groups leaves the reader with the takeaway that, "it's not the people, it's the system"!
The second section seems somewhat disjointed from the first but introduces useful verbs: individuate/integrate, differentiate/homogenize, stabilize/change, the dynamics amongst them, and how all 6 are needed for a balanced system. There is also a discussion on predictictable phases of any society which seems on point.
Overall, the book introduces a few good frameworks for systems thinking but doesn't deliver it in a concise and attractive manner.
