Close a User Story

A user story can be moved to the Completed status when all of its associated tasks are closed. Any team member that is associated with an active team on the product can move a user story to Completed status. Typically, the product owner or scrum master closes the user story after reviewing it and approving that it meets the acceptance criteria.

Follow these steps:

Click Agile, and from Planning, click Backlog.
Select the product name from the Product drop-down list.
Click Details for the user story you want to close.
In the Status field, select Closed.
Save your changes.
