Gordon Campbell, the CEO of United Way in New York City provided this excellent post on
I not only liked Gordon's perspective, but he provided good news on what GiveWell, Charity Navigator, GreatNonprofits and Philanthropedia are doing in this area. Then, he cautions readers (who, I assume, are donors who have never tried to provide "meaningful outcome measures") that doing so takes time and a bit of trial and error.
If you have a donor who is thinking about donating to your organization, read this post and send it to them.
As an aside, I love GiveWell's tag line "Real Change for Your Dollar". Of course real change only happens if someone measures outcomes.....or as the old saying goes "In God We Trust. Everyone else bring the data".
