Academics frequently say the culture is hard to change because the bureaucrat is opposed to major change: I think that’s exactly wrong. You can’t make changes in a large bureaucracy by simply shouting and exhorting. It takes time. Talk to someone in the private sector about marketing and they’ll talk to you about the number of impressions it takes before somebody hears their message. Government is the same way.
— John A. Koskinen, as quoted in the July 3, 1997 Wall Street Journal article “A Business Executive Sees What Works in Government,” by Albert R. Hunt
