Change Management uses a state model to manage change requests.  Not all states are used for all types of change (Normal, Standard, Emergency).   

New (Change Requester) [Normal, Standard, Emergency]

Change request is not yet submitted for review and authorization. A change requester can save a change request as many times as necessary while building out the details of the change prior to submission.  Changes in New state are considered TENTATIVE and not considered an active change request.  Change requester submits the request for approval which advances the change request to Assess state.

Assess (Change Authority review) [Normal]

Peer review and technical approval of the change details are performed during this state. The change authority dispositions the change request.  Approved requests are advanced to the Authorize state.  Rejected requests revert to New state. 

Authorize (Change Authority review) [Normal, Emergency]

The change authority(s) review the request and disposition the change request.   Approved requests are advanced to the Scheduled state.  Rejected requests revert to New state.   

Note:  Add a comment for the change requester explaining the reason for the rejection. 

Scheduled (Change Implementer/Requester) [Normal, Standard, Emergency]

The change is authorized to proceed.  IT staff member advances the change to implementation state.

Implement (Change Implementer/Requester) [Normal, Standard, Emergency]

The change request is ready to be implemented.    

Review (Change Implementer/Requester) [Normal, Standard, Emergency]

The change tasks have been completed. The change requester determines if the change was successful and conducts a post-implementation review.  

Closed (Change Implementer/Requester) [Normal, Standard, Emergency]

Change review is complete and the change can be closed. 

Canceled

When a change is created in error or is no longer valid prior to implementation, the change record should be CANCELED with reason.   A change cannot be canceled if in Review or Closed state.
