A task-based weighting scheme for evaluating these sites is proposed. This extended evaluation metric scheme and provides a more finely-tuned mechanism for assisting developers to improve usability of e-Commerce Web sites, since the user?s task is included in the formulation of the guidelines. In conjunction with this, a novel usability metric prioritising scheme is used to yield information, which is noticeably different from unweighted values. Developers of e-commerce applications are often sceptical about Website usability guidelines. User testing is also usually not carried out because it is expensive in terms of time and expertise. The main reason for developers neglecting current evaluation practices is that they are often vague, and in the case of user testing, too difficult to do effectively. The e-commerce shopping process has been analyzed from a task-based point of view, and a set of task-weighted metrics to be used by developers in evaluating their sites has been proposed. These metrics have been applied to four popular sites and the results from the evaluation have been analyzed. </ABSTRACT></RECORD></RECORDS></XML>
