This is an excellent book filled with practical exercises. I've already begun implementing some of the suggested changes into my organization and I'm looking forward to seeing the results. There's quite a lot to chew on in some of the chapters, so I anticipate rereading and revisiting this book periodically.
Overall this book is a well thought out blueprint for building effective and efficient engineering cultures. If you're on the fence about this book (or maybe you think your team is a lost cause), I can guarantee there's actionable advice in here that all software and product development teams can utilize.
After following several IDesign courses and reading Juval's Righting Software I was left with a lot of questions. This book clarifies much of these questions through good examples.
