“Impact is a critically important concept when it comes to social innovation, generally used in the context of measuring whether social interventions do or don’t work. But conceptually, it’s very similar to the problem of measuring success in a business before you have profits. That’s why lean methods are so perfectly suited to this kind of work. The only real difference is that instead of talking about maximizing shareholder value, Lean Impact talks about maximizing social impact. An advance party of pioneers, some of whom you’ll read about here, is already doing this, but we need more. This book is a way to help add to their numbers. Lean Impact is not only transformational for the social sector, though. My hope is that people in other kinds of businesses and organizations will also pick it up and, after reading about the dedicated people and clear strategies whose stories Ann Mei has gathered, think about how the products and institutions they build affect the world. All of us have more to learn about how we make impact so we can move together into this new era. —Eric Ries, author of The Lean Startup and The Startup Way”
