In Change Management, specifically when using the Change Model framework (introduced in the Rome release to provide more flexibility than legacy workflows), state transitions are governed by specific conditions. For a Change Request to move from the Authorized state (where it has been vetted by the CAB or technical leads) to the Scheduled state (where it is ready for implementation), the system must verify that the necessary approvals have been granted. Therefore, the "Requires" field is set to Task is Approved to ensure that the transition only occurs once the approval engine returns a positive result.
