The basic difficulties with nurse scheduling lie in the necessity of maintaining a certain level of service and skill in the makeup of every shift, while balancing the workload among the nurses involved. This is usually prepared on paper by a head/chief nurse and takes a considerable amount of time and effort.<br>In order to lighten the burden we are aiming to developing an efficient support system that enables a head/chief nurse to concentrate her thoughts on scheduling without needing a prior knowledge of computer operation. In our previous study, task analysis of manual nurse scheduling was performed. The result of the analysis led to the following four user-interface functions that would be needed in a support system; (1) A tool that supports eyes' moving over a spreadsheet, (2) A tool that highlights each nurse and each day that need looking at again, (3) A warning message for a lack of nurses working a night shift, (4) An efficient input tool for marking the cells. Furthermore, in this paper, we divided the scheduler's tasks into those which could be performed by only a computer and those which need a human to complete. We then created an interface based on the above.<br>Five head nurses were given a hands-on demonstration of the support system including the interface. In addition, a chief nurse actually made a monthly schedule using the support system. All six nurses were impressed with its effectiveness and expressed that they wanted to use this system every month, especially the chief nurse.
