Books like Intercom on Product Management

Intercom does these little ebooks on all kinds of topics - Product Management, Sales, Customer support, Onboarding etc. I only read one before this - The Growth Handbook - and loved it. But this one didn't quite hit the mark for me. Intercom is a very successful corporation and these ebooks while being quite general are still high-quality. A good overview of the topic that will benefit people who are novices or non-specialists as an introduction to the topic. Or perhaps if you're confused and out of balance and need to get down to the basics and get your ducks in a row.I guess I expected more. I didn't find out anything new. But I'm probably not the target audience for this one since I've read a bunch on the topic already. It's pretty short, so I don't begrudge the time spent on this.
