Enterprise Architecture (EA) and ITIL, two distinct governance approaches with different perspectives, have become recently dominant between practitioners. However, parallel EA and ITIL projects can lead to wasted resources and a duplication of costs and efforts. This paper proposes an integration by approaching ITIL from an EA perspective and proposes a mapping of ITIL concepts to EA, and a set of models representing the ITIL metamodel using the ArchiMate modeling language. Our goal is twofold: on one hand to give the architect the elements, relationships and models that represent best practices in IT service management, and, on the other, to formally model ITIL for knowledge sharing, stakeholder communication and to contribute to ITIL discussion and validation. For evaluation we shall use interviews and the Wand and Weber ontological method.
