Factors Influencing the Acceptance of Information Systems .

Abstract

User acceptance of IT has been a primary focus in the MIS implementation research for the past decade. Why do users accept or reject information systems? How user acceptance is affected by perceived usefulness, perceived ease of use, and attitude toward acceptance behavior? The present research addresses these questions. The technology acceptance model (TAM) is used as a base model to validate the relationships among the study’s constructs. Afield study (the questionnaire) of a number of users regarding an end-user system was conducted to validate measures used to operationalize model variables and to test the hypothesis. SPSS is analysis technique was used to estimate the parameters of the proposed model. The study findings indicate that perceived usefulness factor has the largest influence on IS acceptance, this construct has significant direct effects on IS acceptance and also exhibit its indirect effects through perceptions and attitude towards acceptance. Ease of use and attitude towards acceptance were found to have an equivalent influence on IS acceptance.
