Enterprise resource planning (ERP) systems have been widely studied during the past decade, yet they often fail to deliver the intended benefits originally expected. One notable reason for their failures is the lack of understanding in users' requirements. This study was designed to understand the relative importance of system quality, information quality, service quality, and their influence on ERP users in the Middle East. The dependent variable individual impact was used to represent the ERP success at the individual level of analysis. The results from this study were compared to the results attained by Petter et al. in their 2008 analysis of North American ERP users. In addition, the moderating effect of users' characteristics on the individual impact variable was examined along an investigation of the items' reliability, internal consistency, convergent, and discriminant validity. Assessing the level of impact from users may help organizations assess the impacts of ERP users' performance and productivity and create training to improve attitudes toward ERP systems.

Organizations make substantial investments in implementing enterprise resource planning (ERP) systems to improve the efficiency and utilization of ERP systems. This study examined the factors influencing and moderating the use of ERP systems. The research variables' hypothetical relationships and moderation analysis were examined through factor analysis and partial least squares structural equation modeling. This study suggests that specific factors significantly influence and moderate the employees' system use. The research results could serve as a reference for vendors when planning the implementation of an ERP system.
