Updating the Actual Effort Required 
Use
When you have completed action items, you should update the actual effort taken on the Effort tab. This gives the person responsible for the issue a realistic idea of the remaining effort required. Any changes you make on the Effort tab are recorded and included in reports. This also allows you to track which action items were clarified and the amount of time taken.
Prerequisites
You have opened the Issue Editor and have completed an action item assigned to you.
