In essence, this book is about taking the Lean Startup concepts and applying them much more broadly - inside companies, non-profits, governments, and or even a lemonade stand. Most of the ideas and proposals in the book make a lot of sense, and it is useful for me to have them collected in this fashion.

Gene Kim and John Willis recorded a set of conversations called Beyond the Phoenix Project to talk about the DevOps movement since the publication of The Phoenix Project.  (It’s available as an audio and a transcription.) I very much appreciate that the thinking behind DevOps has been geared around learning and applying concepts and ideas from all of these areas. I'm sure there are cargo-cultists who simply try to mimic what they see other people doing, but the people who are developing and growing in DevOps are clearly those who are looking at the giants that have come before them, climbing up on their shoulders, doing something new that is relevant to their current view of the world, and then sharing that back with the community to test and refine and develop further. I got a strong sense of excitement and desire to learn from this.
