A Study on EA based IT Governance

In this paper, we propose the Enterprise Architecture (EA) based IT governance. Because of huge size of government organizations, and complexity and many various kinds of tasks, services, and businesses, the architectural design work method for their information systems is too complicated to understand. Thus, so many misunderstandings and problems occur naturally like interoperability problem, duplicate development, waste time and budget, security, etc. To solve this problem, we raise up the EA based IT governance, and probe it systematically. we show down the clear concept definition of EA perspectives of all stakeholders involving digital Government, and EA views of performance architecture, business architecture, application architecture, data architecture, technology infrastructure, and security architecture together with analysing EA Functionality, EA framework, reference models of leading countries EA deployment strategy, EA development work method, artifacts of EA development, and IT governance.
