What is the function of a CAB?

The function of a Change Advisory Board (CAB) is primarily focused on discussing the change landscape and understanding the associated risks and impacts of proposed changes within an organization. The CAB is comprised of individuals with a diverse range of expertise who evaluate changes, ensuring that possible impacts on the service and its users are considered. They assess the necessity and readiness of changes while also ensuring that all stakeholders' concerns are addressed, which ultimately helps in minimizing risks and maximizing the value that changes bring.

In this context, the role of the CAB is crucial for informed decision-making regarding whether to approve, defer, or reject changes. They facilitate comprehensive discussions about potential effects on resources, services, and overall performance, which is essential for effective IT service management.

While other options touch on aspects of change management, they do not encapsulate the primary function of the CAB. Implementing changes directly is not the CAB's role; rather, that responsibility falls to designated teams. Monitoring changes post-implementation and managing project timelines are related activities but are typically handled by different roles within the IT service management framework. These processes support the CAB's ultimate goal of overseeing the change process strategically rather than operationally.
