This article presents the results of a research that aimed at analyzing the influence of the job position and the level of education of the users in their satisfaction with integrated management systems (the enterprise resource planning - ERP). We collected data through semi-structured questionnaires applied to 115 ERP users in 13 different companies, and performed data analysis using the following techniques: descriptive statistics, Spearman correlation coefficient and Chi-Square Automatic Interaction Detector (CHAID). The results demonstrated that the role and position of users have a direct influence on the evaluation of ERPs. In general, the evaluation of the technical and assistant users presented statistically higher results than the evaluation performed by users in supervisory and coordination positions. We could also observe a significant influence of the level of instruction of the users in their evaluation of the systems, especially because employees with lower level of education tended to evaluate more positively the characteristics of the ERPs.
