The Mom Test is a quick, practical guide that will save you time, money, and heartbreak. They say you shouldn`t ask your mom whether your business is a good idea, because she loves you and will lie to you. This is technically true, but it misses the point. You shouldn`t ask anyone if your business is a good idea. It`s a bad question and everyone will lie to you at least a little . As a matter of fact, it`s not their responsibility to tell you the truth. It`s your responsibility to find it and it`s worth doing right . Talking to customers is one of the foundational skills of both Customer Development and Lean Startup. We all know we`re supposed to do it, but nobody seems willing to admit that it`s easy to screw up and hard to do right. This book is going to show you how customer conversations go wrong and how you can do better.
