This book took me longer than was warranted to finish it. This was a fantastically written book that takes a large number of case studies provided by experts in the industry to argue for using the methodologies espoused in their first book the Phoenix Project. While that book was more akin to the Goal, this book was more related to a book like Lean Thinking. Providing case study after case study arguing with clear data and results from a variety of differently sized organization that this is an imperative if you want your business to scale in a structurally sound way.
This book doesn’t by beating you over the head with just the end result. Instead they walk through a series of different steps that any DevOps practitioner will need to follow to fully implement DevOps. However, the authors note that doing most of the steps in the book can really enact massive change in your organization. This book isn’t just for CIOs it is for anyone that has influence in an organization. In fact, the authors point out that many of the people driving these changes did it through their informal organizational authority rather than their hierarchical authority. In some cases they actually made these changes in spite of being directed to do the exact opposite by their leadership team.. In the end, these cases were wildly successful because of the bottoms up adoption where other groups decided they had to do the same thing, if they wanted to achieve similar results.
I highly recommend this book if your organization is struggling or if it is performing well. The tools in this book provide the best way to take a good team and make it a great team.
