Shifts are created for teams. And so is planner.

Currently, supervisors are able to assign activities to team members in shifts. But there is no way to track the status of those activities.

The best way to achieve this is to integrate shifts activities with planner tasks or better replace activities with tasks. So inside the shift, when you create an activity, you are in fact creating a planner task that is automatically assigned to the person(s) who the shift is assigned to. People who work on this activity can mark is as complete when the activity is completed. So the supervisor will know that the activity has been completed. Currently shift does not allow you to update the status of the activity

With this integration, people will also be able to see all tasks assigned to them in shifts in the new tasks app. tasks app will truely become the hub of all task related solutions in Microsoft 365
