technology in approximately 70% of the cases. Comparing with the Technology Acceptance Model (TAM), it could only predict the acceptance of an information technology in approximately 40% of the cases. Additionally, Additionally, UTAUT investigated the effect of four moderators (Age, Gender, Experience, and Voluntariness of use) on the relationships between its constructs and behavioral intention to use an information technology. On the other hand, the validity of UTAUT in the information systems context needs further testing [18].
Therefore in this study the extended UTAUT with some of information systems successful factors will be tested. Thus, the following hypotheses have been proposed for this study.
