Abstract

Enterprise Architecture (EA) has been portrayed as one of the cornerstones of modern IT Governance, with increasing numbers of organisations formally recognising an EA function and adopting EA frameworks such as TOGAF (The Open Group Architectural Framework). Many claims have been made of the benefits of EA, yet little is known as to what organisations actually do or evidence of the benefits they accrue through EA. In this paper we report on the results of a small scale survey painting a snapshot of recent EA practice in large UK organisations across the private and public sectors. A key insight from the survey is that, in practice, EA appears to have a greater effect on business-IT alignment than on technological choices.
