At our company we have a rule where if a task has been created it cannot sit in the "new status" for more than 1 day. This helps alleviate forgotten tasks that reside out there in backlog land. Once we move the status to assigned, that is our indicator that the person assigned will begin their work. If we see an Assigned status but its been a few days and the worker has nothing to show we ask and investigate. This practice helps hold more employees accountable!
