Enterprise Resource Planning systems (ERP) play a significant role in the management of businesses processes. Determining the influential factors that are positioned behind a successful ERP implementation is critical to gain the most value-added from competitive potentials of such systems. The driver of current research is to gain a deeper understanding of the various subjective criteria to measure ERP implementation success with the aim of enhancing the chance success through investigating ERP implementation performance indicators. By exploring the international literature, a comprehensive list of potential success factors of ERP systems is identified which are complementary and critical to the ERP projects. Subsequently, reliability analysis and factor analysis were conducted to categorize the preliminary list into a final set of critical success factors for each of the primary factors. Therefore conducting an Exploratory Factor Analysis, three final factors were proposed as the main factors for evaluating the success of ERP implementation which are social, intellectual, and technical factors. The rest of indicators have been grouped under these categories. The result of current research is a firm basis for the interested scholars and practitioners to formulate their empirical attempts upon and proceed with every aspect of the ERP project according to the guidelines provided.
