This will sound funny as a description of what might look like just another dry business book, but I have deep affection for this book. Not only did I lean on it heavily as a case study example in my doctoral dissertation, but also Charan advocates for so many things I’ve fought for over the years that he helps me feel sane. Leadership development, succession planning, discipleship, equipping the saints… The open secret is that to do any of them well, you have to do all of them. And, further, the deeper you understand any of them, the more you come to realize they’re all the same thing. This book is only 163 pages but I spent months reading it and scribbling madly in the margins. This book is worth the attention it requires.
