Many service providers are now providing applications on the Web that encourage people to do business and satisfy information needs on the Web: educational, banking, shopping, library and medical. The proposed research attempts to investigate the evaluation of these Web-based information services. Three streams of literature are considered: usage of the Web, user satisfaction of the Web, and the complementary field of individual performance and the impact of information technology. Two models emerge from the literature which may be useful in attempting to measure the evaluation of the Web: The theory of planned behaviour and the technology to performance chain. The latter model is the preferred model as it emphasises the fit between technology and the task, an issue not considered by other models. Finally the paper reports on preliminary work investigating the dimensionality of evaluation and usage of the Web.
