Abstract:
Enterprise architecture is one of the critical functions for an enterprise to take a leading role in driving the strategic alignment between business and information technology by comprehensively defined the target architecture from the overall interpretation of business capability, application, data, infrastructure, and security suiting with enterprise strategic planning. The suitable utility of driving this exercise is to refer to the enterprise architecture framework which has several frameworks available for a practitioner to utilize. But there are some challenges of applying the available framework for national governments and their agencies because the proposed frameworks have concentrated on the private sector where some fundamental requirements of government would be specifically needed. This paper has proposed the sustainable government enterprise architecture framework to drive the national strategic planning in the optimum operational process and clear guidance for the information technology organization being able to transform and improve their operational execution for an achievable efficiency of adaptation, simplification, cost management, collaboration, sharable and standardization suited with government strategic goal which accommodated the rapidly changed of service usability as digitalization known as "e-Government" having an emphasis in citizen participation and engagement. This means the proposed framework would substantially improve the sustainability of government information technology and its architecture landscape in coverage of the typical structure of government from federal management offices down to ministries section and functional agencies to strategically drive the efficiency of digital enablement. The fundamental designed idea of this proposed framework has identified five keys principle which are 1) legislation support, 2) top-down target architecture, 3) architecture governance, 4) shared services, and 5) cross-organization collaboration that would be considered as the key critical success factors for achieving the expectation of the exercise. The overall response of the specific expert survey of this proposed framework has demonstrated the consensus at 90% agreeable response which would strongly consider this framework applicable for a group of developing countries as the baseline framework for their digitalized transformation. IMPLICATION OF THE THESIS. This research is specifically designed for accommodating the government transformation program into digitalization of the national public services using the enterprise architecture framework which emphasis on sustainability, efficiency and collaboration.
