Task Priority

The task priority controls the order in which tasks are scheduled during autoschedule, subject to dependencies and task and resources constraints. Autoschedule, therefore, schedules tasks with higher priority ahead of tasks with lower priority. The priority value you enter in the Priority field is used when scheduling task.

If you do not define the task's priority but instead select the Inherited (Priority) check box on this tab, the priority is inherited from its parent task or the next highest WBS level. By default, this check box is selected.
