Korea e-government sets the goal of reaching the full integration stage. In this study, we propose a role model of the National Informatization Agency which is a fundamental organization for achieving the goal. The National Informatization Agency assumes full charge of support functions needed for consistent and efficient accomplishment of all the e-government projects, and those functions include e-government planning, project administration, national IT resource operation, national standards management, and project audit and evaluation. The proposed role-model is expected to be a theoretical basis for innovative government at informatization.
