Without a doubt, Inspired is my number one reading recommendation for anyone in a product-related role. Marty Cagan, who worked for and with countless tech companies in Silicon Valley, presents a battle-hardened, comprehensive approach to product management that can scale from startups to enterprises. The core elements of his philosophy include people, product, process, and culture, and for each of these he shares some theoretical background, a lot of practical advice, as well as tools and techniques one can immediately take into action.

Furthermore, the book is perfused with case studies to highlight how product managers in the messy real world addressed particular challenges at organizations such as Google, Adobe, the BBC, Microsoft, and Netflix.
