A project team is a group of users associated with a project. Users listed under the Staffing tab of a project are the users who make up the project team.
Depending on what email notifications your Workfront system administrator enables, users on a project team are notified of various actions on a project. For more information about enabling email notifications, see "Enabling and Disabling Event Notifications."
NOTE Ensure you keep the project team membership updated in order to avoid sending notifications to users who do not need information about a project.
To use role-based approvals on a project, users must be assigned to the project team and have the correct job role assigned in their user profile.
See the following articles for information on how to set a user up for role-based approvals:
If you don't want to require the user to be on the project team for role-based approvals, you can control this in approval settings. For more information, see "Establishing Approval Settings."
If a user is listed on the Staffing tab of a project, that project appears on the Projects I'm On tab in the Projects area.
NOTE If you are the creator of a project, the project remains on your Projects I'm On tab, even if your name does not appear on the Staffing tab of the project or if your name has been removed from that tab.
