In large companies the gap between business and IT is usually bridged by designing and maintaining an enterprise architecture (EA). An enterprise architecture is a high-level representation of the enterprise, used for managing the relation between business and IT. Large organizations benefit from modeling their enterprise architectures in order to coordinate IT projects and the management of IT...

With the rapid development of economic globalization and enterprise informatization in emerging markets, the key to making the most out of the two rests within how to integrate and share information as well as how to provide critical and accurate data for enterprise decision makers. However, at present, many enterprises are still in the early stage of research and exploration into the concrete ...

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 addressed. We argue that a sophisticated ...

Enterprise Architecture (EA) models are structured, object-oriented models that typically conform to an organization-specific, i.e. customized, meta-model that evolves over time. Enterprise architects commonly use different branches of such an EA model to plan future states of an EA with respect to their origin–the current state of an EA. It is particularly interesting for enterprise architects...

While a considerable amount of research on enterprise ontologies exists, work showing how to use ontologies for enterprise architecture (EA) analysis is scarce. We present our ongoing work on creating analyzable enterprise models using EA-based ontological representation. Our contributions are twofold: first, we show how an existing EA modeling language can be leveraged to create EA ontology an...

Identifying, gathering, and maintaining information on the current, planned, and target states of the architecture of an enterprise is one major challenge of enterprise architecture (EA) management. A multitude of approaches towards EA management are proposed in literature greatly differing regarding the underlying perception of EA management and the description of the function for performing E...

In recent years, enterprise architecture (EA) management has emerged to one of the major challenges for enterprises. When looking for guidance in this field companies can choose from a variety of EA management approaches, which have been developed by scientists, practitioners, and governmental organizations. However, these approaches differ significantly in a number of characteristics and espec...

The US Federal Agencies’ Chief Information Officer Council in its guide to Federal Enterprise Architecture has defined an Enterprise Architecture (EA) to be “a strategic information asset base, which defines the mission, the information necessary to perform the mission and the technologies necessary to perform the mission, and the transitional processes for implementing new technologies in resp...

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 guidelines. This paper derives a sophistica...
