Manually balancing the workload of people can be a cumbersome task for any project manager. Fortunately, Project’s resource leveling feature can help you by automatically delaying or splitting tasks so the resources assigned to them are no longer overallocated. You control which tasks can be leveled by setting priorities for them. Learn more.
On the Gantt Chart, double-click the name of the task to bring up the Task Information box.
On the General tab, in the Priority box, enter a number between 1 and 1,000. Tasks with a lower priority are delayed before those with a higher priority.
If you don't want Project to level a task, such as a task that must start on a specific date, set its priority level to 1000. By default, priority values are set at 500, or a medium level of control.
Project management tip Using the Task Information box to set priorities on multiple tasks can quickly become tedious. Use a sheet column instead. Right click on a column heading, click Insert Column, and click Priority.
The task called “install plumbing” has a priority of 800. This means that Project could move it during leveling as the priority is lower than 1000. If it is more important to the schedule that this task not be moved over other tasks, raise the priority to 1000. At 1000, , Project would not move this task when resources are leveled.
