An Analysis of Enterprise Architecture for Federated Environments

Abstract

The challenge of business and IT-alignment has been a major concern for IT managers over the last few decades, as an increased congruence between the two aspects improves effectivity and results in organizations. Enterprise Architecture (EA) addresses the alignment by providing a holistic model-based view of the organization. However, previous research has revealed some generic discrepancies in prominent EA frameworks regarding their support towards more decentralized organizational structures. Following a case study research of a federated organization this paper analyzes in depth The Open Group Architecture Framework (TOGAF) EA framework, and based on identified discrepancies how it should be extended to provide an adequate support. By enabling the establishment and maintenance of a federated EA, the proposed extension should further increase the business and IT-alignment for federated organizations.
