I'm gonna start by saying I've never enjoyed the ones I call "tech books", as in I'm a fiction reader. My thing is fiction.
BUT I do read books related to my work and hobbies and sometimes, rarely though, I find real gems. Most of the time not, I just pray for the pages to somehow shrink.
Now that you understand the context, I can honestly say this ain't a bad book. This is actually a good one. No doubt it's helpful and interesting for software/QA professionals, but for me, as a person having worked on support roles for the tech industry for the past 7 years, it's so comprehensive yet so easily understandable!
Having witnessed the eternal dev-QA battle multiple times, I can confirm that this book has everything you need in order to understand the importance of quality in your company, the underlying processes and also how you should approach it to move it to the center of your product development. Cause it does belong there.
I loved that it's not a bs-theory delivering book, but rather an insightful collection of real stories and examples in the industry. And I love that this book, as well as even the authors' company, was created exactly because they've reached the conclusion that QA is central by themselves, in their own hands-on practice.
The overall feeling is that this book is a compilation of best practices and ideas, without the ballast of the boring research underneath, but providing all the resources you need in order to lead quality in your team (long list of online resources, recommended reading list & references).
TL;DR: Good book, no bs, lots of practice, resources. Recommend.
