This study was design to grope the suggestions leading synergic effects by bridging the gap between headquarters and branch office, and so to identify the infra-system of contract foodservice management company (CFMC) necessary for operating any kind of branch office including school, hospital and business and industry (B＆I). Among 8 categories consisted of infra-system in CFMC, 'C8. Evaluation ＆ analysis for branch office's operation' was the most important category in the headquarter's viewpoint, while 'C3. Sanitation management system' was the most important category in branch office's viewpoint. In support and application, 'C3. Sanitation management system' was the highest category in both headquarters and branch offices including school, hospital and B＆I. As a result of analysis on gap between main and branch office in importance, support and application in 8 categories, the efforts of communication and community of perception for infrastructure were needed, because 'C4. Education ＆ training for human resource management (HRM) system' and 'C8. Evaluation ＆ analysis for branch office's operation' in importance, 'C2. Menu management system', 'C4. Education ＆ training for HRM system', 'C6. Facility ＆ utility support system' and 'C8. Evaluation ＆ analysis for branch office's operation' in support had a gap. Correlation analysis to grasp the relation between importance of infra-system and headquarters' support or branch office's application showed that headquarters's importance and support were correlated positively in 'C3. Sanitation management system', 'C6. Facility ＆ utility support system', 'C7. Customer satisfaction management system' and 'C8. Evaluation ＆ analysis for branch office's operation' and branch office's importance and application were correlated positively in 'C1. Procurement ＆ food processing system', 'C5.

Now a day, Information and its related system has been more important in our competitive environment. In this situation, there is also an important thing that we must take into consideration, that's the employer's resistance. Until now we have little material concerning the issue, user's resistance. Owing to that, it's a little hard to study the user's resistance against the IS. Dealing with the resistance effectively helps companies save a great deal of cost and build the information system successfully. This paper takes the Markus's theories about user's resistance. According to the theories, there are three keys theories affecting resistance. To sum this, people-oriented theory, system-oriented theory and Interaction theory. To complement the theories, this paper includes another theories related with resistance and takes total seven factors causing user's resistance. Among these seven factors, four factors have a meaningful effect on the user's resistance, that is, Self-efficacy, System Complexity, Threat of the one's status and politics and System Staff's service quality. Managers and system-related company should keep it in mind very carefully, and I hope they make the best use of the result of this study.

This paper describes the differences of the information system's success factors to improve the end-user's performance according to the job characteristics. A modified model of DeLone and McLean's IS success model is proposed with the two added variables of the top management concern and the IS department support. The model is validated using data collected from a field study of 3872 users on 3 Korean companies. ANOVA, correlation analysis, and stepwise regression are used to test research hypotheses. The results of the study indicate the following implications. First the top management concern and the IS department support have the significant relation with the system usage and the user satisfaction. Second, the system quality has an influence on the user satisfaction more than on the system usage. And the information quality has an influence on the system usage more than on the user satisfaction. Third, the system usage has more relations to the user's performance in the logistics function and R&D function. The user satisfaction has more relations to the user's performance in the sales and the A/S function. Therefore information system strategy to increase the user's performance must be differentiated according to job characteristics.
