How to: Create a Team Project Group
You can create security groups for your team project to better meet the security requirements of your organization. Creating a security group is an efficient way to grant a specific set of permissions to a group of users on your team project. Make sure that you allow only the minimum permissions necessary for the group, and add only those users or groups who must belong to this new team project group. If you must create a group that is not project-specific, consider creating a server-level group instead. If you must create a group that has permissions across multiple projects, see How to: Create a Server-Level Group.
To perform this procedure, you must be a member of the Project Administrators group. For more information about permissions, see Team Foundation Server Permissions.
To create a team project group
In Team Explorer, select the team project for which you want to create a group.
On the Team menu, point to Team Project Settings, and then click Group Membership.
In the Project Groups dialog box, click New.
In the Create New Team Foundation Server Group dialog box, in the Group Name box, type the name for the team project group.
In the Description box, type a description for the group.
After you have created a team project group, you must add the new group, give the group the appropriate permissions, and add members to the group. By default, a team project group is created without any permissions granted.
