Assessing the success of Information Systems (ISs) has been identified as one of the most critical issues in IS field. Several conceptual and empirical studies have been conducted to explore this confusing yet important issue. A huge debate continues concerning the appropriate set of variables that can be used to determine the users' perception of ISs success. However, studies relating to this issue within the context of Arab countries are few and lack the ability to propose an appropriate evaluation criterion for Arab organizations. This study is one step ahead and aims to propose and empirically test an evaluation model for ISs success from the users’ perspective. Accordingly, this study is of two folds including the theoretical fold which deals with the conceptual elements leading to the appropriate evaluation criterion and the empirical fold which deals with testing the proposed model. Among the five factors that were explored in this study, four factors were determined as influential factors including system's usefulness, user's technical capabilities, information quality and management support. System's ease of use was excluded from our proposed model. The findings of this study are expected to add value to ISs' investments as well as to increase the rate of success for costly ISs initiatives.
