If your looking for specific case studies or a "drilled down" discussion, you generally will not find it with this book. It does, however, give some good general guidelines for conducting research, problem solving, presenting, and client interaction. As with most general or somewhat abstract models, this book provides general principles that can be applied specifically to your current situation. For example, the processes involved in data collection, brainstorming, issue analysis, hypothesis construction, etc., can be applied to any topic in any area. I found the writing style easy to read and concise, with minimal amounts of obfuscation. Basically, it seems to me, the bedrock of the Mckinsey way is long hours, data distillation, and thorough and exhausive data collection. All told, I found it a worthwhile read.
