I watched on YouTube an interview with the author, Bill Schmarzo, and found interesting what he said and his career: he is not the typical millennial data guru but a seasoned professional with many decades of experience in the BI and analytics world (way before it was "the sexiest job").
I think this book does a good job introducing key aspects of the most important data and analytics concepts. I did a master in Data Mining so I already knew them, but the author provides a practical framework and approach for almost everything you need to develop as a data lead so it's useful also for the ones with more experience.
The text becomes a little too repetitive (concepts and examples) and has a more high-level approach than I expected (many parts are written in the style of a textbook while using more of his personal experience and challenges could be more useful, I guess).
It's clear that he loves to teach: all the main algorithms are explained in a very easy to understand way and also the steps of every processes (in some moments it even reminds me of the "For Dummies" series, but with a more academic language).
I found the Analytics Hub and Spoke Analytics section interesting and also the last chapters in which he explores score development, data monetization, envisioning and chief data monetization officer role.
