ITIL als Common-Practice-Referenzmodell für das IT-Service-Management — Formale Beurteilung und Implikationen für die Praxis

In the course of increasing customer orientation in the IT sector, IT service management becomes more important. Especially the de facto standard ITIL receives attention of IT management at present. Deficits of the ITIL reference model are often ignored, benefits are only assumed and a lot of misunderstandings exist. Uncertainties, unfulfilled expectations and problems during the accomplishment of ITIL projects are the result. In this context the paper deals with a critical analysis of the ITIL reference model. It fulfils a formal evaluation of the model on the basis of established criteria. On the basis of this evaluation implications for IT management are derived. Findings are derived from four case studies as well as an in-depth analysis of the ITIL documentation itself.
