The IS(Information System) strategic planning must be based on objectives and strategic planning of the organization. The IS strategic planning for a hospital is not different from other organizations. Perhaps it can be more important than other types of organizations. Hospitals possess unique characteristics which hinder implementation of the IS. Therefore when the objectives and the focus of IS are clear, the resources can be allocated effectively and integrated IS can be applied. This study will suggest general objectives and strategic planning of the hospital. Thereby we will propose the strategic planning and development planning model of IS for hospitals. Suppose that the objectives of a hospital are the quality service and effective costs reduction. To achieve these objectives we will propose the strategies such as procurement of qualified physician and personnel, maximization of productivity, maintenance of good services and comfortable environments, and redesign of business process. Thus strategic planning of IS for hospital organizations is established as the follows: 1. The objectives of the IS for a hospital are to monitor the outcome of medical services and hospital performance, and to deliver the doctor's order in order to provide the quality services to patients. Therefore the IS design strategy for the hospital should be planned to achieve these objectives. To establish these goals all hospital data should be computerized and the IS should be able to monitor the performance of the hospital. Direct dat input environment is essential for the system. 2. The direction of master plan of the IS for a hospital is the integrated system. The methods of approach for the integrated system is selected to cover the all primary data from medical services rather than functional units. 3. The objectives of development of medical service information system, first phase of master plan, include : on-line input and delivery system of all doctor's orders, inquiry about all test in any time at any places in the hospital, automated scheduling of nursing work at nurse station, hospital billing, and ancillary services. 4. In order to achieve the goal, CSFs(critical success factors) to be resolved are : doctors must enter their own orders, the employee consents to replace the manual paper work with IS, the system is maintained with rapid response even though peak time, many functions must be constructed in the short period. 5. Therefore development strategic planning of IS is suggested to maximize user's convenience, specially, for doctors, to apply several data servers with independent functions, and to introduce client-server system, and to use the commercial DBMS.
