This is an excellent book, easy to read, a good overview of the issues of CICD and how to overcome them in an high level manner. That's perhaps the only critique, no enough details, helicopter view mostly. But that's fine for people with already a good grasp on Agile development. This book confirms, kind of echo chamber, what all Agile mindset aficionados think. For those developing for specific hardware, there is a chapter about emulator vs. simulator that is very interesting in this particular context.
