Consider a given public policy problem. Everyone sees the problem is complex. From this comes an impulse to control all its elements. Everyone sees the importance of improvement. From this comes an impulse to command improvement. Together these produce the 'blueprints' we so often see: lists of actions all of which must be taken, in a certain order, over a period of time. But in the public sector blueprints usually fail. Mechanisms of "mutual adjustment" usually work better.
