In Roles, you must create roles for the users who review the content generated by Content Authors. You can create multiple Content Approval roles based on the content the users review. In Task groups, you select task rights to manage workflow tasks. You then use security assignments to associate the Content Approval roles with the Content Approval task groups to apply security for approvals. For information about these task rights, see Approval and Workflow Task Rights.
When you create a workflow in Workflows, you assign approval rights to roles. When the Content Author creates a part that uses the workflow, a user in the Content Approval role must review and approve the content before it appears on your website. The user selects whether to publish or reject the content of the part.
