ERP시스템 사용자 인지가 만족도 및 지속적 사용의도에 미치는 영향 : 시스템 상호작용과 사회적 상호작용의 조절효과 중심

The goal of this study is to analyze the effects of the ERP system pre-usage user's cognition on post-usage user's cognition and the effects of post-usage user's cognition on satisfaction and continuous usage intention, and also analyze that system interaction and social interaction have moderate effects on the relationship between pre-usage user's cognition and post-usage user's cognition. Pre-usage cognition, usefulness expectation and attitude are used as independent variables, post-usage cognition, expectation confirmation and post-usefulness are used as parameter, and system interaction and social interaction are used as moderate variables. As a result of the analysis, usefulness expectation has effect on post-usefulness, attitude has effect on expectation confirmation, and post-usage cognition has effect on satisfaction and continuous usage intention. Only system interaction has positive moderate effect with the attitude to expectation confirmation. In terms of additional analysis for the direct effect analysis of system interaction and social interaction on expectation confirmation, post-usefulness, satisfaction, and continuous usage intention, for the expectation conformance and post-usefulness had more significantly effects than pre-usage user's cognition. For satisfaction and continuous usage intention, system interaction had significantly effect. It shows that the usefulness expectation and attitude perform a role of reference point to decide satisfaction and continuous usage intention through the confirmation process for expectation confirmation and usefulness. However, the post-usage user's cognition is influenced by the system interaction and social interaction rather than the pre-usage user's cognition. And also the satisfaction and continuous usage intention are seriously affected by these variables. Therefore, the introduction of useful ERP system and the organizational culture of establishing ERP systems are most important.
