Allow users to assign a 'workload to a task'.
Allow users to assign a 'workload' to a task. Not just start and enddate, but an amount of hours lets say. The task might span a month, and in that month you have i.e. 16 hours to spend on that specific task.
I came here to post the same idea!
This would make the Planner tool truly functional from a management perspective. If all the users enter their projects, duration, and workload %, that can be rolled up into a managers report to monitor resource levels. Right now there is no way to tell when someone schedules a task for the next 6 months if that is their 100% project or 5% as fill-in work.
