When you create a contract workspace, you specify a team of users to work on the project.
A project team consists of project groups. Each project group has different roles, which specify the permissions for the users in that group for the CW in question. The permissions specify the objects (documents and tasks) the users can access and what actions the users can perform in that project. Creating groups with different roles enables you to assign users with different responsibilities to the project team. Group permissions determine:
- Ownership
- Visibility
- Editing capabilities
- Review and approval
Group members can be individual team members or groups. For example, Legal is a system group. System groups differ from project groups. Project groups are specific groups of people that are working on a project. System groups function for all SAP Ariba solutions, not just a single project. However, you can add a system group to a project group to associate all system group members with the project.

Note
Groups defined in a project differ from those you add from the Ariba Administrator page. Creating a group of users in Ariba Administrator allows administrators to organize the users into a group but does not associate the group with any projects. However, groups defined this way can be added to team projects, as is the case with Legal in the screenshot above.
