Doug Kimball is the real deal for product marketing knowledge, practice and leadership. After leading product marketing functions and developing product marketing strategy and messaging for more than 5 companies across industries - he decided to write a book about it.
I was fortunate to report in to Doug at one of those companies and the strategy and various mental models work! It was surreal to read this book because on several occasions I was brought back to a moment in time where I learned a specific concept. I particularly like the whiteboard brainstorming session we all when through as a team to improve in visual storytelling on page 96.
When talking about product marketing one of the golden nuggets that Doug drops about communicating to buyers was:
"Don't tell me what the product does tell me why I should care."
Best book that I have read on this topic. Highly recommended!!
