- ZeitschriftenartikelARIS Method Extension for Business-Driven SOA(Wirtschaftsinformatik: Vol. 50, No. 6, 2008) Stein, Sebastian; Lauer, Jens; Ivanov, KonstantinServiceorientierte 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.
- TextdokumentDigital Transformation in Higher Education – The Role of Enterprise Architectures and Portals(Digital Enterprise Computing (DEC 2017), 2017) Sandkuhl, Kurt; Lehmann, HolgerDigital transformation is considered as one of the mega-trends in industry and the public sector. One of the sectors with potential for digital transformation is higher education in universities and university colleges. Many universities and schools developed digitization strategies and new kinds of offerings for their traditional target groups and for new, non-traditional target groups. However, digitization and digital strategies often are limited to digitizing the content of lectures and to opening access to education modules by offering them online. We argue that digitization strategies should include a wider focus and propose that enterprise architecture management could provide an important contribution in structuring digitization efforts and that enterprise or knowledge portals could play a role for implementing the strategies.
- ZeitschriftenartikelGestaltung hybrider Wertschöpfung mittels Architekturen – Analyse am Beispiel des Business Engineering(Wirtschaftsinformatik: Vol. 50, No. 3, 2008) Zellner, GregorMehr denn je sind Unternehmen im zunehmenden Wettbewerb dazu gezwungen, Differenzierungsstrategien zu etablieren. Die Generierung innovativer Leistungsbündel bestehend aus materiellen und immateriellen Leistungsbestandteilen ist eine solche Strategie und wird als „hybride Wertschöpfung“ bezeichnet. Um Unternehmen bei ihrer Veränderung zum hybriden Lösungsanbieter zu unterstützen, werden Vorgehensweisen und Techniken benötigt, welche in eine formgebende Struktur eingebettet sind. Architekturen sind solche Hilfsmittel, die eine strukturierte Veränderung von Unternehmen unterstützen können. Die Zielsetzung des Beitrags ist es zu identifizieren, welche Anforderungen an eine Architektur für hybride Wertschöpfung zu stellen sind und inwieweit die Architektur des St. Galler Business Engineering diese Anforderungen erfüllt.AbstractThe increasing competition forces enterprises to establish differentiation strategies more than ever. The creation of innovative bundles, consisting of material and immaterial elements, is such a strategy and known as “hybrid value creation”. In order to support enterprises during their change towards a hybrid solution supplier, procedures and techniques are needed which are embedded in a certain structure. Architecture Frameworks can support such a structured transformation of enterprises. The intention of the paper is to identify requirements for architectures for hybrid value creation and to check these requirements by using the St. Gallen Business Engineering Framework.
- ZeitschriftenartikelHow companies can benefit from Enterprise Architecture Management in the Digital Transformation Process – An Extended Research Model(Enterprise Modelling and Information Systems Architectures (EMISAJ) – International Journal of Conceptual Modeling: Vol. 14, Nr. 4, 2019) Reichstein, Christopher; Sandkuhl, Kurt; Härting, Ralf-ChristianA successful digital transformation in enterprises requires surpassing infrastructural flexibility within firms and a high level of IT competence in order to meet changing business requirements. Digital enterprises face the challenge of combining business and IT to benefit from existing technological achievements in the digital age. Previous studies have shown that there are critical factors that influence the benefits of Enterprise Architecture Management (EAM). However, factors influencing the digital transformation have not been considered yet. An alternative and iterative research approach develops new success factors for enterprises that benefit from EAM. In this context, this paper builds on a qualitative research approach to examine additional factors and their impact on EAM. The approach is based on an extended structured literature review to build a new empirical research model. In addition, the indicators were validated by three different industrial case studies reflecting the benefit from EAM within the digital transformation process. The results of the extended research models and case study validation show that factors aggregated to the determinants IT Landscapes, Internal Business and EAM Establishment have substantially impact on the benefit of EAM in enterprises. Moreover, the authors found two factors (firm size and external business) in the model moderating & the effects on the benefit from EAM.
- TextdokumentPositioning IT4IT in the face of classic Enterprise Architecture Frameworks(INFORMATIK 2020, 2021) Hartmann, Andreas; Auth, GunnarIT4IT 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.
- ZeitschriftenartikelUnternehmensarchitektur – Literaturüberblick und Stand der Praxis(Wirtschaftsinformatik: Vol. 50, No. 4, 2008) Aier, Stephan; Riege, Christian; Winter, RobertDie Gestaltung und das Management der Unternehmensarchitektur haben in den letzten Jahren stark an Bedeutung gewonnen. Die Herausforderung besteht darin, Entscheidungen wie z. B. die Gestaltung von Geschäftsfeldern und Produkten, deren Abbildung in Geschäftsprozessen und Organisationsstrukturen bis hin zur Implementierung durch Anwendungssysteme und dem Betrieb der dazu notwendigen Infrastruktur durch eine konsistente, aggregierte Gesamtsicht des Unternehmens zu unterstützen. Dieser Beitrag gibt einen Überblick zum Verständnis und aktuellen Stand des Themas Unternehmensarchitektur in Literatur und Praxis. Dazu wird eine Reihe von Publikationen der letzten Jahre vergleichend gegenübergestellt. Das Verständnis und die Umsetzung der Unternehmensarchitektur in der Praxis werden anhand der Ergebnisse einer empirischen Erhebung bei Unternehmen aus dem deutschsprachigen Raum dargestellt.AbstractOrganization and management of enterprise architecture have gained increasing significance in recent years. Enterprise architecture management is based on a consistent, aggregate model of the enterprise in order to support decisions such as the design of business areas and products, corresponding business processes and organizational structures as well as application systems and infrastructure operations. Stakeholders have heterogeneous requirements concerning the views on enterprise architecture. The resulting model itself has to be manageable and has to deliver benefits.This article provides an overview of the state-of-the-art of enterprise architecture / enterprise architecture management in the literature as well as current practices in companies. In addition to a literature overview, current practices are presented based on results of an empirical study.
