An Extended Framework for ERP Post-Implementation Success Assessment

Implementing enterprise resource planning systems is a sophisticated, lengthy and costly process which tends to face serious failure. Thus, it is essential to perform the success assessment at the post-implementation stage of an ERP project to evaluate how much the system has succeeded in achieving its predetermined objectives. This paper proposes a practical and extended framework for assessing a firm's ERP post- implementation success. The factors contributing to the post-implementation success assessment have been adapted from the original model of Ifinedo et al. (2010) encompasses service quality, system quality, information quality, individual impact, workgroup impact, and organizational impact surrogates. Also, a new surrogate of interorganizational impact proposed in this research. Using this model, the firm's ERP system success can be determined and the required improvement projects can be proposed to promote the success level. The proposed model is then applied to a real international company in the field of manufacturing and supplying turbines to measure the firm's ERP post-implementation success. Finally, the results of the assessment are discussed.
