Abstract: ERP systems have been adopted by many organizations in the past decade. These systems have revolutionized organizational computing by facilitating integrated and real-time planning, production, and customer response. While some companies have achieved significant efficiencies through ERP, others have complained of failed implementations, budget overruns, and disappointing performance. This paper draws upon Diffusion of Innovation (DOI) theory and Information Systems Success (IS) theory to develop and test a model of ERP implementation success. Results reveal that top management support and training are positively related to user satisfaction, while perceived complexity of ERP and competitive pressure show a negative relationship. Consensus in organizational objectives and competitive pressure are positively associated with perceived organizational performance. Post-hoc analysis identifies user satisfaction as a moderator between certain DOI characteristics and organizational performance. This leads to the proposal of a new model of ERP implementation for future research.
