The higher the risk level, the stricter the authorization procedure.

In SimpleOne, once a change request requiring authorization is raised, it goes to the authorization stage. The status of the request changes to the Authorization. For this, special authorization tickets are sent to all necessary authorities depending on the Authority level (see the table below for more information).

In such a ticket, every recipient is proposed to approve or reject a request.

If all authorization tickets have been approved, then the change request is considered to be successfully approved. The status of the request changed to the Scheduled.

If there is even one authorization ticket was rejected, then:

• all other authorization tickets must have been rejected automatically too;
• the change request is considered to be rejected and goes back to the authorization stage;
• the status of the request is changed back to Registered.

For the emergency changes, due to their high importance for business services or CI, the relationship between the Registered and Authorization states is one way. It means that emergency tickets cannot be rejected.

Change Authority level

Notes:

• The Change Manager controls the lifecycle of all changes.
• CAB - Change Advisory Board. This group of people advises Change Manager in prioritization, authorization, and scheduling of Changes.
