tl;dr - proscriptively certain that this way is The One True Way
Product Management suffers from one failing above all others: unclear definitions. This book seeks to solve that by being Very Clear about what the definition is. Not what it could or should be, but definitively must be. Unfortunately, the evidence given to support the assertion is "all these prior definitions didn't work" and even that much is only justified by relying on common knowledge and a glowing recommendation from the person writing the Forward.
What this book delivers is a logically consistent approach to the topic. Surprisingly, this is the first time I've found somebody attempt to do that in a pragmatic context, for which the author should be commended. The bulleted list of lists of what to think about may not be the answer you need for your career, but it does force you into a framework where the default choices hold real content and allows your edits to work within context.
