When you create a work item, you can choose whether to grant access to your work item to members of your work group. By default, work items are set to be visible to other members of the same work group, who can relaunch a work item interview, update answers and generate new assembled documents. If you do not want other members of your work group to collaborate on your work item, you can set the work item to private.
When you create a work item, you can use the toggle to determine the privacy setting:
The work item's detail pane displays the privacy status of the work item.
You can only change work item privacy settings if you are the owner of the work item or an administrator.
The work item updates to allow access only to the owner and administrators. It is no longer visible to other members of the work group.
