Should Philanthropies Operate Like Businesses?

It's your money, and you're willing to give some of it away to a worthy cause. But you want to see results. Measurable progress toward agreed-upon goals. Regular proof that your investment is achieving maximum impact. That's the way businesses operate, and charities should be no different.

That's one way to look at it, anyway.
 
Others argue that things work differently in the world of nonprofits and social change. Tackling some of society's biggest problems is unlikely to produce anything like the steady, chartable path of progress that investors require. And that's simply something donors have to live with if they want to help those most in need.
 
So what should you expect of your charities? Businesslike efficiency? Or something more intangible, less-easily defined?
