전사적자원관리(ERP)의 확산에 관한 실증연구: 정보기술/정보시스템 혁신의 관점

The recent dramatic growth of ERP has changed the way organizations conduct their businesses, and resulted in significant tangible and intangible benefits being realized by participating firms. Despite these various benefits, firms still have problems in implementing and diffusing ERP due to some reasons, such as resistance to the change. This study primarily aims at identifying what factors are significantly affecting the diffusion of ERP system and finding out how these identified factors can be effectively managed. Drawing upon past research on innovation diffusion, information systems(IS) implementation, and ERP implementation, a research model was derived. This model was used to examine the role of some determinants in influencing the extent to which ERP system is diffused within organizations. The 9 factors (organizational compatibility, complexity, cost, IS maturity, top management support, championship, elapsed time since initial adoption, project planning and management, ERP modification ratio) were selected as independent variables of the model. In order to measure the extent of ERP diffusion which is the dependant variable of this model, vertical and horizontal diffusion concept is used. The vertical diffusion represents the range of ERP system functions that support business process of a company, and the horizontal diffusion means how widely ERP system is used within the organization. The 44 companies of total 128 samples responded to the survey. To analyze the results of this empirical study, the multiple regression analysis was performed. As a result, it was shown that the championship and the project planning and management had a strong influence on both the vertical and the horizontal diffusions, and that the elapsed time since initial adoption had an influence only on the vertical diffusion. On the other hand, the effects of the innovation characteristics and the IS related factors were not verified to be significant. This is because ERP concept generally places greater emphasis upon understanding business processes, rather than information technology itself in marked contrast to other IT/IS innovations. It was founded that the current degree of ERP diffusion in Korean companies is very low, because ERP in Korea is still in the initiation stage. Due to this ERP situation in Korea, this field study was analyzed with relatively small sample size. and thats the limitation of this study.
