The importance of Enterprise Architecture (EA) to enterprise transformation has been identified by an increasing number of companies as well as public sector actors. However, the literature to date does not provide much empirical evidence of the benefits of EA. In this article, we evaluate empirically the potential benefits of the EA approach in Concept Development and Experimentation (CD&E), which is considered a tool to drive strategic transformation in the military community. The DeLone and McLean information system success model is used as an evaluation framework. The research method in the article is a case study. The results of the case study are analyzed statistically. The results suggest that the EA approach could benefit CD&E. The EA approach supports the further utilization of the military concept, which is a life-cycle stage preceding military capability development. The applicability of the evaluation framework needs further research.
