When you start a review in live mode, Identity Governance initiates a running review instance and notifies any person or role specified in the Notifications settings of the review definition. A review instance will always be associated with the version of the review definition used to start it. After a review owner approves the review run or individual review items, Identity Governance notifies fulfillers if they have change items. For more information, see Checklist for Managing a Review in Live Mode.
