SUMMARY
This study is aimed to test the manager’s satisfaction of the managers using the ERP and to test the influence of job satisfaction towards the performance in the decision process by the manager. The measurement of the satisfaction towards the ERP system will be conducted using the end user’s satisfaction computing model (EUCS), using the content, accuracy, formal ease of use, and timelines attributes (Doll and Torkzadeh, 1988). Whereas, the performance is measured using the instrument which was developed by Nicolaou (2000) consisting of 2 (two) question items about the reporting and continuing control, 7 (seven) items of questions adopted from the study results of Spathis and Constantinides (2004).The data were collected through a survey using questionnaires distributed to companies that have used the ERP system. The data analysis used the Partial Least Square method with SmartPLS program. The results show that the concept of EUCS has a conformation and there is a significant effect between the ERP system user satisfaction with the manager’s performance, especially in the decision making process. This result contributes to the concept of EUCS and supports previous research related to user satisfaction in different types of information system applications.
