What is NOT a core consumer role in ITIL 4?

In ITIL 4, the core consumer roles are well-defined, focusing on individuals who interact directly with services or are involved in their governance. The customer, sponsor, and user are all recognized as key roles that play an integral part in the consumption of IT services.

Customers are those who decide on the purchase and use of services, often determining the requirements and ensuring that the services meet their needs. Sponsors are typically responsible for the funding and accountability of the services, ensuring that there is sufficient support and resources for the service management activities. Users are the individuals who actually utilize the services to perform their job functions and achieve their objectives.

On the other hand, stakeholders represent a broader category of individuals or groups who have an interest in the service and its performance. While they can influence or be influenced by the service outcomes, they do not fit into the defined core consumer roles like the others. Stakeholders may include anyone from management teams to external parties who are interested in the service's success, but they do not directly consume the services in the way that customers, sponsors, and users do. Thus, the distinction lies in the direct engagement and roles in the service lifecycle, making stakeholders less specific to the consumption of services compared to the other roles.
