Which of the following is NOT a role within Change Management?

In the context of Change Management, the roles involved are specifically oriented towards managing, approving, and overseeing changes within an IT service environment. The Change Manager is responsible for overall management and administration of changes, ensuring that all changes are assessed, approved, and documented effectively. A Change Approver, typically someone in a leadership position, reviews and approves the proposed changes to ensure that they align with organizational objectives and carry minimal risk.

A Service Owner plays a vital role as they are responsible for the delivery and management of a specific service, which includes involvement in the change process to ensure that service changes do not negatively affect service quality or performance.

While a Help Desk Operator is an integral part of the IT support structure, their primary duties revolve around representing first-line users, assisting with incidents, and addressing user queries. Their focus is generally on resolving issues and providing support rather than managing or approving changes. Therefore, a Help Desk Operator does not hold a specific role within the Change Management process itself, making this option the most accurate in response to the question about roles in Change Management.
