Abstract
In recent years, Enterprise Architecture (EA) has become a discipline for business and IT-system management. While much research focuses on theoretical contributions related to EA, very few studies use statistical tools to analyze empirical data. This paper investigates the actual application of EA, by giving a broad overview of the usage of enterprise architecture in Swedish, German, Austrian and Swiss companies. 162 EA professionals answered a survey originally focusing on the relation between IT/business alignment (ITBA) and EA. The dataset provides answers to questions such as: For how many years have companies been using EA models, tools, processes and roles? How is ITBA in relation to EA perceived at companies? In particular, the survey has investigated quality attributes of EA, related to IT-systems, business and IT governance. One important result is some interesting correlations between how these qualities are prioritized. For example, a high concern for interoperability correlates with a high concern for maintainability.
