While successful businesses usually have a decision-making process that produces quality decisions, that process can falter, and often it is because too much time has been taken to make a decision. The process of decision-making should be a structure of business procedure, but the time spent in the process for any given decision should be based on the specific decision to be made. This determination is very much part of the art of decision-making.
When decisions take too long, the principal culprit is usually the fear of making a bad decision.
