PublicationAn Engineering Approach to Enterprise Architecture Design and its Application at a Financial Service Provider(Köllen, 2008-11-27)
;Kurpjuweit, Stephan ;Schmitz, Otto ;Schulz, Joerg ;Thomas, André ;Loss, Peter ;Nuettgens, Markus ;Turowski, KlausWerth, DirkIn analogy to classical engineering disciplines, this contribution discusses characteristics and requirements of an engineering approach to enterprise architecture design and proposes components and a top-level structure of an approach to address these requirements. The proposed components can partially be realized by existing work; partially they lay out the research path towards a mature engineering discipline of EA design. Core components of the proposed approach have been applied and evaluated at Deutsche Leasing AG, a globally operating financial service provider based in Germany.Type: conference paperVolume: LNI P-141 -

PublicationA Federated Approach to Enterprise Architecture Model Maintenance(Ges. für Informatik, 2007-10-08)
;Fischer, Ronny ;Reichert, Manfred ;Strecker, StefanTurowski, KlausEnterprise architecture is gaining acceptance as an approach to manage change and foster IT/business alignment by (1) propagating strategy and process changes to the software and infrastructure level, by (2) supporting consistent business transformation enabled by technology innovations, and by (3) decoupling business-oriented and technology-oriented architectures. Due to constant change in business as well as in technology, enterprise architecture management is a permanent process rather than a one-time effort. To keep enterprise architecture models up-to-date, a well-engineered maintenance concept including processes, roles and schedules is needed. This paper discusses the shortcomings of existing approaches to enterprise architecture model maintenance, proposes a federated approach, and reports on its implementation at a large financial service provider.
