摘要:Enterprise architecture (EA) is one of the most important tools for implementing e-government effectively and delivering high-quality information technology services to citizens. To develop a robust EA research model with key success factors, we apply the theory of organizational change proposed by Burke and Litwin, using the concepts of transformational and transactional change. The analysis is conducted by using South Korea’s EA project launched in 2003. This study classifies EA implementation in the South Korean public sector into three stages and explains the characteristics of each stage from the organizational change perspective. We raise the issue of EA application level compounded by the problem of diverse EA definitions and discuss the difficulties of EA implementation based on the framework of organizational change. In addition, 20 EA experts are surveyed to confirm the findings of this study. Finally, we propose a new research model for future empirical study based on the presented findings. We believe that this study, as an in-depth review of EA implementation from an organizational change perspective, will benefit EA experts from a practical point of view, as well as academics from a research perspective.
