A Comparison of National Enterprise Architecture and e-Government Perspectives

Enterprise Architecture (EA) has been adopted as a framework for all tier of the organization to deliver effective IT services and management. E-Government is a public service for all citizens. The basic needs are accessibility, equity and engagement. Thus, EA is relevant to e-Government because it establishes all stakeholder's participation leading to governance. Citizen also requires transparency and participation in monitoring process of the government project. EA ensures the best practices in business alignment with IT implementation and integration. It results in the efficient management of e-Government services including the shared resources/ services and the rational use of technology. This study selected the world front-runners are Denmark, Australia, South Korea, Estonia, and Singapore to compared the EA approach with e-Government perspectives. It found that there is no best approach for all countries. Each nation should develop and customize the specific detail or context to align with the nationwide vision. The EA should be legislated as the digital transformation/e-Government policy. The fundamental IT initiatives are electronic identification, communication and core infrastructure given as national cloud. The EA approach leads governance and standard of sharing and integration for the entire enterprise including business, data, service and technology across the country.
