Abstract
The study is mainly aimed to present and evaluate a conceptual model for user
acceptance of information technology that is performed by a descriptive/survey
research regarding its nature. The conceptual model was designed through investigating
existing models and identification of effective variables on acceptation of
information technology and was tested by studying attitude of users of the system in
organization under study including administrative staff, technical staff, intermediate
managers 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 three
main hypotheses and at the confidence level of 99% and ranked at three top variables
respectively by the average scores of 5, 3.46, 3.14. Meanwhile the indexes of
“adaptation with work conditions” and “communications facilitation” were identified
as the most important indexes and the “continual use of computer in future”
and “strict recommendation of use of computer to others” as the least important
indexes in the process of user acceptation of information technology. Also, among
sub-hypotheses under study only two ones were approved demonstrating “age”
and “sex” are influencing factors on the relation between two variables of “effort
expectation” and “behavioral intention” as modifying variables. In addition, the
under studying variables had the most and the least scores among top and intermediate
managers by the scores of 19.27 and 20.15 respectively
