This study proposes a framework that examines factors that influence the successful implementation of ERP systems. Six critical success factors (enterprise wide communication, business process reengineering, project management, team composition and competence, ERP system quality and ERP vendor support) were identified and used to collect empirical evidence. In addition, organizational culture was examined to determine whether it has any moderating effect on the six variables in relation to ERP implementation success. A survey questionnaire was distributed to organizations with ERP. The targeted respondents were ERP users within the companies. A total of 384 responses were used for analysis. The data obtained was analysed using the Structural Equation Modelling. The results indicated that that ERP implementation success is influenced by enterprise wide communication, project management, team composition and competence, ERP system quality and ERP vendor support. It was also found that organizational culture moderates the relationships between enterprise-wide communication, project management, team composition and competence, ERP system quality, ERP vendor support and success of ERP implementation.
