LITERATURE REVIEW

The prior studies are believed to be the essential basis to establish the theoretical model. Information system success has received considerable attention by researchers in this arena. Previous contributions in this field were in different directions because of differences in views held by authors. The review of the literature is undertaken in two directions: information system success and e-learning system success.

Information System Success

Success of information systems is believed to be the central issue in the information systems field. Because of considerable amounts of money and efforts being spent on IT/IS projects, the evaluation of their success has became a critical issue. So, substantial research has been performed and considerable attention paid to this issue. The diversity in approaches of researchers has led to the development of different methodologies and models to measure information system success. The contributions to measuring information system success can be classified in four approaches.
