Along the same lines as the Pallotta talk, check out this 1-minute, 40-second video, "If We Want Our Funding to Change the World..." at http://youtu.be/z_w3v6TxJZQ. My organization, Donors Forum, released it last week as part of a project called “Real Talk About Real Costs.”
If you want to receive occasional updates on the project, and be part of the movement to promote “real talk,” you can sign up for occasional emails athttp://eepurl.com/wH2nT
And also check out this page http://donorsforum.typepad.com/realcosts/2013/01/suggested-reading.html, which has lots of resources on measuring impact, nonprofit overhead, nonprofit finances, and effective grantseeking and grantmaking.
