The Task Scheduler combined with out robust Notification System, you can assign it and forget it.  The assignee will receive custom notification of a new task assigned to them with all details included.  Task can be marked to show on assignee and assigners high priority dash board when within so many hours of due date/time. For faster entry users can duplicate task as well.

View recurring options.

Once task is completed or more information is needed, the assignee can enter followup information before closing the task or simply close the task.  Notification will go back to assigner when followup information is entered or task is complete.

As a complete task, the printout alone with all followup information as well as any supporting documentation are at the click of a mouse button.
