Enterprise Architecture in E-Government Application: A Systematic Literature Review

E-government initiatives have enabled government agencies to deliver public services and information efficiently and effectively. Designing and sustaining an e-government application using an Enterprise Architecture (EA) approach is necessary to align e-government applications with government objectives while avoiding unwanted system failures. Although several review papers discuss EA, they have all focused on nongovernmental organizations. This literature review aims to identify and analyze current EA practices in government agencies using 32 primary studies, following Kitchenham’s guidelines. The VOSviewer application was used to develop research questions based on the Population, Intervention, Comparison, Outcome, and Context (PICOC) criteria. The findings of this literature review demonstrate that government agencies mostly implement EA in the design of e-government applications, integration between EA and other standards, and phases of the implementation of EA as architectural solutions to government agency issues. The local governments, which are the government agencies that mostly implement EA in designing e-government applications, have used The Open Group Architecture Framework (TOGAF) as a guideline for integrating cloud and big data standards in the business, information, application, and technology phases to address data integration issues.
