It is true that procrastinating managers use some of the tactics that no-decision managers use to avoid decision-making, and it is possible when starting to work with them that there could be confusion between the two.
But, instead of procrastinating only over decisions, as no-decision managers do, they procrastinate over everything: tasks, managerial activities, actions and of course decisions. They generally work on tasks and actions that they enjoy and delay other tasks until the last minute. When a deadline is close procrastinating managers will go into a frenzy and force their subordinates to work on everything at the last minute.
When a deadline is close for no-decision managers, they do nothing. They act as though they are unconcerned especially if it involves some sort of decision-making. A deadline for a no-decision manager is not something to become anxious about.
In the end though, it is easy to tell the difference between these two manager types. A procrastinating manager will eventually make a decision. It will probably be made in haste, possibly too late, and sometimes may not be a good one. A true no-decision manager, however, will never make a decision. They keep delaying and delaying and never decide; what I call ‘permanent procrastination.’
