Who is responsible for final authorization of a change in Change Management?

In the context of Change Management within IT Service Management, the CAB (Change Advisory Board) Manager plays a crucial role in the authorization process for changes. The CAB Manager is responsible for overseeing the Change Advisory Board, which is comprised of key stakeholders from various areas of the organization. This board evaluates the potential impacts, benefits, and risks associated with proposed changes.

The final authorization of changes is a significant responsibility, as it ensures that the changes align with the organization's strategic goals and operational stability. The CAB Manager, therefore, has the authority and oversight required to make informed decisions based on the recommendations from the CAB, considering technical and business perspectives.

While other roles, such as the Change Requester or Service Owner, may be involved in proposing or discussing changes, they do not have the ultimate responsibility for approving changes. The Change Implementer is tasked with the execution of approved changes but is not responsible for their authorization. This structured process helps to ensure that changes are implemented efficiently while mitigating risks to the organization's services.
