This paper utilizes an empirical method that employed responses from 158 companies adopted Enterprise
Resource Planning (ERP) in order to identify factors influencing ERP introducing performance. To achieve
this purpose, we extracted influencing factors such as change management and information system maturity
from relevant studies and analyzed independent and interactive effects between them. Our results show that
proposed change management factors affect introducing performance, and information system maturity has a
significant interactive effect on the relationship between introducing performance and change management
factors excluding top management concern. From the results, this paper provides the implications and
importance of change management and information system maturity for improving the performance.
