I learned a lot from Marty Cagan’s INSPIRED. Now that I’ve joined the Product side, I could actually relate to a lot of the things mentioned in the book. The book isn’t just for startups; INSPIRED also covers issues faced in larger companies. But if you’re not a product manager or not a product enthusiast, this book won’t work for you. This book is very specific to the job, for which reason INSPIRED has been so successful and helpful to its target audience.
Manage your expectations: although the book’s subtitle is “how to create tech products customers love,” INSPIRED focuses more on how to build a great product team and how to foster an innovative culture. Ideally, this would serve as a foundation for product managers to lead their teams to create great products, but for anyone looking for a how-to manual or direct instructions, try something else. (In Chapter 58, Marty Cagan mentions Sprint, which I’d already planned to read sometime after anyway.)
Great foundation. I would recommend to aspiring or current product managers in tech companies, startup or not.
