It's difficult for me to evaluate this book:
- Thinking about what it brought to me at this point of my professional career: not much, nothing new indeed (probably I have read "too much" in my life XD ).
- Thinking about what it might bring to people not too familiarized with Lean, DevOps, Systems thinking, etc.: it can be a great and recommended reading (too long maybe).

I would recommend it specially to people who don't have "too much" experience/knowledge in the topics mentioned before... or people like me who need to read it because you always get something new (like more arguments for better "selling" certain principles and practices around product-software engineering).
