I heard the authors speak at an event and found them thoroughly engaging, which lead me to try to read Fearless Change, although I really can't find anything to recommend it.
The "patterns" are, with a few exceptions, beyond obvious. Here are a few sections that would lose nothing if you reduced them to the title alone: "Ask for help," "Brown Bag," "Do Food," "e-Forum," "Involve everyone," "Just do it."
In the "Do Food" pattern, you will learn the following: "Usually a meeting is just another ordinary, impersonal event." Fascinating, tell me more. "Mention the availability of food when you advertise the event." Right-oh. Anything else? "Chew the food thoroughly before swallowing, in order to prevent accidental choking death." Okay, I made that last one up, but you get the idea.
The organization is also strange. There's kind of a narrative progression of patterns up front, which is relentlessly cross-referenced with the full pattern sections. It's not clear to me if I'm supposed to be jumping back and forth between the patterns, or reading the narrative bit all at first, then onto the full patterns, and the authors don't answer that question. Fearless Change is really cross-referenced to death. Every pattern mentions 5 other patterns to use. "Hint: If you're out of food money, have a Brown Bag (113)." That's helpful, if you don't know what a brown bag is and need to look it up.
Last but not least, a lot of the writing tends toward pointy-haired boss speak. For instance, the authors incessantly refer to people in their examples as "change agents" instead of their actual roles.
You may get something out of this by borrowing someone else's copy and skimming lightly, as I wish I had done.
