Predicting Success of ERP System by using a hybrid approach based on FDEMATEL and FSAW

The implementation of enterprise resource planning is complex, and the failure rate remains very high. This study proposes a prediction approach based on the FDEMATEL and FMCDM for ERP success. The literature has reported over 30 critical success factors for ERP implementation, but companies typically do not know to exploit them. First, about 21CSFs from literature and expert opinion are elaborated into key performance indices, which are categorized in three groups; organizational, tactical and technical factors. These factors associated with each stage of ERP implementation by ten local ERP experts. Second, a three stage ERP implementation model is proposed. Further, it uses fuzzy DEMATEL and the evaluation of ten experts to evaluate weighting of each CSFs, after that FMCDM method uses to obtain possible rating of success of ERP performance and remedial actions are identified if the performance is below expectation. The proposed approach is helpful to predict the success of ERP without actually adopted ERP in companies. Iran Khodro Khorasan Company is conducted to illustrate the effects of the assessment model, which is also currently being used by a consulting company specializing in ERP implementation. With further evaluation by local experts, the model has the potential to serve as a guideline for ERP implementation in other countries. The results confirm that organizations consider organizational factors less than other factors, some of important factors are top management support, identification of ERP objects, change management, sufficient financial budget, project management, sufficient implementation team, effective communication and training.
