User acceptance of information technology: factors, theories and applications

Abstract

IT has dramatically improved the productivity and effectiveness of any organisation. For this reason, over the last few decades, both developed and developing nations have invested heavily in IT. However, a significant amount of these investments failed to achieve the expected results, causing growing concern about the feasibility of those investments. There is much literature dedicated to discovering the factors for success or failure of IT projects. Among the identified factors is the human factor, which was found to be one of the most important determinants for the success or failure of any IT project. Research has shown beyond fear of contradiction that the many advantages offered by IT cannot be realized until IT tools are commonly used. This paper examines this pivotal issue concerning the concept of user acceptance of technology, the concept of user acceptance, IT adoption theories, and the applications of these theories. The study systematically reviews the technology acceptance model and its basic constructs, namely perceived usefulness and perceived ease of use.
