    ARIS Method Extension for Business-Driven SOA
    (Wirtschaftsinformatik: Vol. 50, No. 6, 2008) Stein, Sebastian; Lauer, Jens; Ivanov, Konstantin
    Serviceorientierte Architekturen (SOA) sollen Unternehmen die benötigte Flexibilität geben, um sich veränderten Marktbedingungen kurzfristig anpassen zu können. Um diese Vorteile zu nutzen, muss SOA mit anderen existierenden Ansätzen wie Geschäftsprozessmanagement und Enterprise Architecture Management integriert sein. Der Artikel beschreibt eine Erweiterung der ARIS-Modellierungsmethode für Geschäftsprozessmanagement und Enterprise Architecture Management. Die Autoren haben zunächst ein SOA-Metamodell durch Abstraktion von bereits existierenden Modellierungsmethoden sowie durch Experteninterviews entwickelt. Anschließend wurde das SOA-Metamodell auf ARIS abgebildet, um eine konkrete Modellierungssprache für serviceorientierte Unternehmen zu bieten. Die ARIS-Erweiterung erlaubt es, Servicearchitekturen zu beschreiben und zu verwalten, Services Maßnahmen, Projekten und der Unternehmensstrategie zuzuordnen und Services für die Geschäftsprozessautomatisierung zu identifizieren.AbstractService-oriented architecture (SOA) promises making companies more flexible enabling them to react quickly to changing market conditions. To leverage those advantages, SOA must be integrated with other existing approaches like business process management and enterprise architecture management. The authors describe how they extended the enterprise architecture management and business process management modelling method ARIS. They first created a SOA meta model by abstracting from existing modelling methods as well as extracting expert knowledge through interviews. In a second step, they mapped the SOA meta model to ARIS to provide a concrete modelling language for service-oriented enterprises. The ARIS extension allows describing and governing service architectures, describing services, linking service development initiatives to projects and company strategy, and discovering services for business process automation.

    Positioning IT4IT in the face of classic Enterprise Architecture Frameworks
    (INFORMATIK 2020, 2021) Hartmann, Andreas; Auth, Gunnar
    IT4IT was introduced by the industry consortium The Open Group (TOG) in 2015 as a new reference architecture for the business view of IT management. Since TOG declared IT4IT to be a new standard and it apparently has an architecture focus, its potential use in enterprise architecture management has become a topic under discussion. In this study IT4IT is reviewed and compared with the classic enterprise architecture frameworks TOGAF and ARIS using evaluation criteria collected from literature. The results show that, although IT4IT has structural and topical similarities to classic EAFs, in particular the architecture focus and different views, its purpose and context of use is clearly different. Conforming to the concept of a service-oriented architecture (SOA), IT4IT is value oriented, service-centric, data driven, and automation focused; its position can be described best as part of an IT-related extension of a comprehensive EAF. Thus, IT4IT calls for integration with a classic EAF – without erroneously replacing or overwriting existing standards.
