Abstract
Much of research has applied the Task-Technology Fit (TTF) model and the Technology Acceptance Model (TAM) to organizational information systems (OIS) for work-related activities. The Web essentially is a large information system (IS) and is often used for non-work activities. Yet, few studies have related the TTF model and the TAM to the use of Web-based information systems for non-work activities. This paper synthesizes TTF and TAM models and tests whether they are applicable to the Web. The results show that the TAM applies very well to predict the Web user's performance, but the TTF model just produces a weak relationship. The study suggests that the performance of the Web users can be improved through (1) improving the perceived usefulness, (2) improving the perceived ease of use, and (3) having a more aligned task-technology fit.
