Identification and Ranking the Factors Influencing User Acceptation of Information Technology

Abstract

The study is mainly aimed to present and evaluate a conceptual model for useracceptance of information technology that is performed by a descriptive/surveyresearch regarding its nature. The conceptual model was designed through investigatingexisting models and identification of effective variables on acceptation ofinformation technology and was tested by studying attitude of users of the system inorganization under study including administrative staff, technical staff, intermediatemanagers and top managers in the frame of five hypotheses and ten sub-hypotheses.The results showed three variables, “effort expectations”, “execution expectations”and “mental norms” (social influence), were approved in the frame of threemain hypotheses and at the confidence level of 99% and ranked at three top variablesrespectively by the average scores of 5, 3.46, 3.14. Meanwhile the indexes of“adaptation with work conditions” and “communications facilitation” were identifiedas the most important indexes and the “continual use of computer in future”and “strict recommendation of use of computer to others” as the least importantindexes in the process of user acceptation of information technology. Also, amongsub-hypotheses under study only two ones were approved demonstrating “age”and “sex” are influencing factors on the relation between two variables of “effortexpectation” and “behavioral intention” as modifying variables. In addition, theunder studying variables had the most and the least scores among top and intermediatemanagers by the scores of 19.27 and 20.15 respectively
