Should a ministry be run like a business?

I just ordered Jim Collins' new , book Good to Great and the Social Sectors. I like the title of his first chapter, "Why Business Thinking Is Not the Answer".

We must reject the idea -- well-intentioned, but dead wrong -- that the primary path to greatness in the social sectors is to become more like a business.

In business, money is both an input (a resource for achieving greatness) and an output (a measure of greatness). In the social sectors, money is only an input, and not a measure of greatness.
