Abstract

The aim of this paper is to explore the elements that make up Enterprise Architecture (EA) frameworks and evaluate the kinds of purposes EA could serve for in e-business. Using literature research, we derived five main elements of EA frameworks. Next, we applied the EA elements on a running case at a large multinational firm currently migrating towards e-business. The case study shows that EA is well suited for descriptive purposes, making EA a valuable communication and evaluation instrument for management. We also found that in contrary to the current belief EA has limited value for management when pursuing adaptability purposes such as the design and/or redesign of information systems. Comprehensive tooling support is still a major bottleneck when implementing e-business solutions. We suggest further research on specifying the conceptual EA elements in the tooling support.
