In this article, our purpose is to introduce the results of a new approach to assess the information system success. It is based on the DeLone and McLean model and was applied on two domains. The chosen domains are banking sector being the most customer of information technology and construction industry as the least computer-intensive sector. The work methodology used to evaluate the information system performance is a combined approach of the two most popular multi-criteria decision making techniques: AHP and TOPSIS. Based on the results of this technique applied on studied sectors, we can obtain a horizontal comparison at the sector level and optimize the choice of the best system.

The purpose of this study is to enhance the DeLone and McLean information system success by adding a SERVQUAL instrument to evaluate the service quality dimension. An integrated model for evaluating the information system has been proposed. One of the most popular multi criteria decision making techniques, namely AHP was used to determine the weights of each criterion and sub-criterion of the model in order to identify the most influential criterion on information system’s evaluation. System quality dimension has a strong influence on information system success (0.39) followed by information quality (0.22). The proposed model could be used to enhance information system performance evaluation.
