This study is a measurement of effectiveness to a job process for the hospital information system (HIS) used in the hospital industry. Using the effectiveness scale that I developed in the questionnaire of the ISO9241-11 quality model, I measured the importance level of HIS and its significance on a job practices in the large general hospitals within the country. The questionnaire showed that the importance level of domestic HISs was highest in the system used by staffs(mean=3) and to reduce a job process and increase the efficiency of work.
