The transparency created by enterprise models is a valuable support for organizational engineering and especially enterprise transformation. However, current approaches are hardly suitable to also create transparency of the enterprise transformation process itself. The paper at hand contributes a systematic approach for capturing dynamics of enterprise(More)
Enterprise Architecture (EA) models capture the fundamental elements of organizations and their relationships to serve documentation, analysis and planning purposes. As the elements and their relationships change over time, EA planning becomes increasingly complex. An analysis of existing methods shows that the complexity of dynamics is not sufficiently(More)
Enterprise Architecture (EA) models provide information on the fundamental as-is structure of a company or governmental agency and thus serve as an informational basis for informed decisions in enterprise transformation projects. At the same time EA models provide a means to develop and visualize to-be states in the EA planning process. Results of a(More)
Enterprises are subject to continuous change driven by top-down planned transformation projects as well as by bottom-up initiatives realizing what is called the evolution of the enterprise. Enterprise architecture (EA) planning presents itself as a means for facilitating and controlling this change. Nevertheless, the methods and models of EA planning(More)
Kurzfassung Integration ist eines der vielschichtigsten Themen der Wirtschaftsinformatik. Es adressiert so unterschiedliche Herausforderungen wie die Geschäftsprozessintegration, die Integration von Applikationen oder die gegenseitige Ausrichtung von fachlichen und informationstechnischen Strukturen.

Modern enterprises face the challenge to survive in an ever changing environment. One commonly accepted means to address this challenge and further enhance survivability is enterprise architecture (EA) management, which provides a holistic model-based approach to business/IT alignment. Thereby, the decisions taken in the context of EA management are based(More)
The service orientation approach emerged form the software engineering community and has now become a widely discussed design paradigm for almost every aspect of an enterprise architecture (EA). However, experience from cases studies has shown that it is necessary to explicitly differentiate service categories in EA, its goals and its resulting design(More)
