In their book, Dave Gray, Sunni Brown, and James Macanufo have researched and codified a number of strategies to help people generate new ideas, work through them, and act on them. But in making this book, the authors have done more than create a valuable reference of approaches for idea generation and decision-making: they've also begun to create a shared language that we can all make use of.
Rather than going into the games cold, they begin by placing them in the context of a larger framework, allowing the reader to better understand how each game could best suit their situations and mix and match with each other.
Those who've read Gang of Four patterns in the programming world, have dabbled with various design pattern libraries, or are familiar with other collections taking the approach of Christopher Alexander's "A Pattern Language" may find the format recognizable. As they never mention a pattern approach, I'm not sure if the authors intended it that way, but the book is structured in a very similar fashion: naming each game, explaining the basic layout of how it works, and when to apply it.
As with the other pattern-related books, the authors do not claim to know it all, and in fact expect others to discover more patterns -- in this case, the games -- and for the ones they mention to be refined over time. Also similar to the pattern-based approaches, they encourage the reader to use the ones they feel will best fit together for what they need to accomplish, rather than use them in very prescriptive ways.
In naming each game and using a pattern-like structure to explain them, it not only makes it easy to read each individual game, but also helps codify them -- packaging them up into a shorthand that people came refer to and apply quickly with shared understanding.
The authors mention using the games in 'knowledge work' situations, but I feel that it is really applicable to any industry. The things that they are really talking about address real LEADERSHIP, rather than industrial-age, control-focused management approaches that apply less and less to even manufacturing industries today. (I find a lot of ideas in the book reflecting the organizational learning approaches advocated by Senge and Mintzberg.)
You'll find the likely-used-too-often SWOT method in this book, and probably many more that you're already familiar with. But like me, I bet you'll read a few more that you'll be thinking about applying in a future meeting, project, or even when you're stuck for ideas working on your own.
Read the first 75 pages to start, and look through the rest of the games as you can, and keep it nearby as reference for your next strategy session.
