The service portfolio defines the IT organisation's activities and customers at strategic level. This then governs the scope of the service structure. In turn, the IT services are taken from the service structure and presented to the customers in a service catalogue. Categories for ticket management, allocation of responsibilities within the IT organisation, economic follow-up and documentation of knowledge are organised in the next step in accordance with the structure that has been developed in the service structure.
The Service Catalogue Management process produces and administers the service structure and the service catalogue.
