E-Government Interoperability Enterprise Architecture. Systematic Literature Review

Public administrations have been introducing innovations such as digital initiatives and those initiatives are related to interoperability between systems managed by different government agencies. Despite those efforts citizens and businesses are still claiming for better digital public services. To understand interoperability challenges, this paper presents a systematic literature review addressing 1) the levels of interoperability that must be considered in government services, 2) the key motivation for interoperability, and 3) the challenges in the e-government ecosystem. From 680 papers we selected 28 to conduct a deep analysis. As a result, we have identified three core interoperability layers: technical, semantic, and organizational. We also present e-government interoperability project challenges related with strategic, policy, technological and barriers, and common modeling language. On the other hand, using ArchiMate, we have identified the elements of the e-Government interoperability motivation layer and used them to test how Enterprise Architecture can manage e-Government interoperability
