Key Issues in Enterprise Architecture Adoption in the Public Sector

This paper examines the challenges of enterprise architecture (EA) adoption in public sector organisations. So far, demonstrating the benefits of EA has appeared difficult in this context, and the results in transforming public sector remain modest: Both the penetration and the maturity of EA appear rather low. In the academia, however, the adoption of EA has gained less interest than the EA development and methodologies. Hence, there is a need for research on what are the challenges of EA adoption, and how to overcome them. This paper presents the results of an expert survey on the challenges of EA adoption in the Finnish public sector. The analysis of quantitative data, supported with a qualitative data, reveals three interrelated factors: Resistance towards EA, Relevant EA goals, and the EA practices in use. Managing the identified key issues classified in these three broad concepts would be the prerequisite for institutionalising EA and making it a legitimate practice. The findings extend the current knowledge of the public sector EA with practicable ideas how to increase the level of penetration and maturity.
