What does a Service Catalogue provide according to ITIL 4?

A Service Catalogue in ITIL 4 serves as a crucial resource that provides a central source of information specific to all live IT services. This includes details about the services currently available to users and customers, encapsulating their attributes, service levels, and how to access them. Having a well-maintained Service Catalogue ensures transparency and enhances communication between the IT department and its stakeholders, contributing to effective service management.

While other options may reference relevant information, they do not accurately capture the primary function of the Service Catalogue. For example, the first choice suggests it covers potential IT services, which could encompass future offerings rather than those currently operational. Unapproved IT services, mentioned in one of the alternatives, would not typically be included in a Service Catalogue, as it focuses solely on services that are officially recognized and available. Additionally, aspects like budget and funding detail, which are essential for financial management, fall outside the scope of what the Service Catalogue specifically aims to provide. Thus, the Service Catalogue's core purpose is to document and inform about services that are currently live, emphasizing its role in effective service delivery.
