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 Private: they invisible to other members of the same work group, so only you can access your work items. If you want other members of your work group to collaborate on your work item, you can set the work item to Public. The other members can then relaunch the interview, update answers and generate new assembled documents for the work item.
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.
