This book by Gilles Gravelle helps social and faith-based nonprofit organizations provide meaningful and convincing answers to the most important question a donor can ask: “What difference is your cause making?” It’s the so-what test few charitable organizations are capable of passing. Instead, they mostly provide anecdotes and one-off stories. Results are characterized as a large number.

It’s not enough these days. Donors want to know that stories about change are not isolated examples, but evidence that positive impact will continue to increase. This book argues that measuring qualitative change is possible and not as hard as you think. Not only will you see the possibilities, but you will also know how to recognize significant impact and how to report it to your donors.
