Though this book is ideal for product managers it is also excellent for anyone involved in building products. While the first book helped us shape our approach to building products at Workiva, the second edition has helped to clarify and refine many of those processes as we have scaled. I think this is also a great book for engineers and engineering managers as it captures many other aspects of how outstanding product teams work together. I always appreciate Marty's clear and concise writing style and his ability to break down complex concepts into very simple ideas and patterns. The included profiles of some outstanding product people help to show how these principles work in real life and are not just abstract concepts. This is the best book I have seen to date on building great products and great product teams!
