프로젝트 구현과 사용자 만족도의 관점에서 본 성공적인 ERP시스템의 구현을 위한 핵심 요인에 관한 연구 = Critical Success Factors of Successful ERP System in Project Implementation and User’s Satisfaction Perspective

다국어 초록 (Multilingual Abstract)

Successful ERP (Enterprise Resource Planning) system implementation in organizations can enhance their competitiveness and productivity. However, ineffective implementation of ERP system or failure in management of the system even after the successful ERP project completion can pose the indifferences of ERP users as well as the crucial risks of degrading company’s productiveness. Therefore, it is crucial to fully understand the critical success factors for the successful ERP system implementation. This study redefined the successful ERP system implementation in terms of the IS (Information Systems) project success and the ERP users’ satisfaction. Then, through the previous research, this study defined ‘perceived usefulness’, ‘perceived ease of use’, and ‘internal support’ as minimal critical success factors for the successful ERP implementation. In addition, a research model was established and the hypotheses were verified in order to find out the relationships between the critical success factors and the success indicators by defining ‘ERP system usage’ as an intervening variable. As a result, it turned out that the ‘internal support’ has the most significant effect on the ‘ERP project success’. Also, this study found that the ‘perceived usefulness’ and ‘perceived ease of use’ impact the ‘user’s satisfaction’ the most. We hope that the result of this study would be used as a guideline for those who planned to implement an ERP system.
