Also, it may offer knowledge articles for users to attempt troubleshooting. Service Catalog is critical in the “shift left” approach, enabling users to be self-sufficient in addressing their technical issues. In the eyes of business customers, the Service Catalog has the value of identifying the details of all service offerings – those that can be requested by users and those which cannot. The Business view of a Service Catalog includes cost information, SLA and also clarifies the roles and responsibilities involved in the delivery of the services. From a technical perspective, the Service Catalog is a source of practical information needed. It may include details related to approval processes, escalation, relationship to other services, etc. Therefore, the catalog presents the services in an organized way that allows users to know what specific services they can request and how, while giving the IT Service Provider clear and easy to understand instructions to execute them. Which perspective does YOUR organization need? It depends on your particular needs and structures.
