There is some feeling that a large number of controls do constrain creative impulses. It seems to be that a person's mind must be able to run free without constraint to generate new innovative concepts. Data from advertising agencies and R&D labs do suggest that corporations emphasizing creativity tend to reduce the number of controls used. Data is just not collected on intermediate activities such as time in the office or manner of dress. The emphasis tends to be on the end-result of activities (output controls) rather than upon the activities themselves (behavior controls).To the extent that managers attempt to regulate the activities which go into creativity, they may destroy the very thing.
