Business/IT alignment has become one of the most relevant concerns on organizations. 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. In this paper we propose an EA and ITIL integration using Archi-Mate as a common frame of reference. We also want to point out that implementing ITIL is like implementing any other architecture change and demonstrate it by using TOGAF to perform an ITIL implementation on ArchiSurance, a fictitious organization from the well known ArchiMate case study.
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.
The Tudor IT Service Management Process Assessment, also known as TIPA, is a process assessment framework that meets two standards: the ISO/IEC 15504 Process Assessment and ITIL. The main benefits of a TIPA for ITIL assessment are to provide an IT service management plan and a management framework for process improvement. However, this framework does not have any relationship between EA principles that are useful in understanding organizations and the business. Meaning, it is difficult not only to assess the process maturity based on EA principles but also to relate the process improvement plan presented in TIPA with these EA principles. By using the EA modeling language ArchiMate, we can provide a graphical notation and therefore, creating a bridge between EA and this framework making it easier for organizations to improve their processes and achieve desired process maturity levels.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
