Feedback And Task Analysis For E-Commerce Sites.
Paula Kotzé · 2002
Abstract: Developers of e-commerce applications are often sceptical about Web-site usability guidelines. User testing is also usually not carried out because it is expensive in terms of time and expertise. The spectacular usability and commercial failure of some sites attest to the folly of such practices. 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. This paper therefore offers an alternative. The e-commerce shopping process has been analysed 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 sites and the results of the evaluation are given.
