After you have data in your catalog, and (optionally) have customized review display column and configured reasons for review actions by accessing the Administration menu; you can begin creating reviews. This is where a set of reviewers examine who has access to what in their environment. Administrators can create review definitions for the following types of objects:
Access permissions, accounts, or technical roles of a set of users
Unmapped accounts
Accounts, which includes both mapped and unmapped accounts, and optionally, the permissions assigned to the accounts
Membership of a set of business roles
Only users with the Review Administrator or Global Administrator authorization can create and modify review definitions.
