Abstract [en]

The Usability of a website can be evaluated using various methods. One of the methods is usability testing, which is widely used and employed by the usability tester due to its low cost and user friendliness. The results of usability testing can be affected positively or negatively by several factors such as evaluator’s role, number of users, test environment, tasks, usability problem report, usability measures, and other factors. For more than a decade, the number of users plays a key role in usability testing. Previously done study [12], has shown that correlation exists between the number of user tasks and the number of issues found.

As an extension and follow-up of the recent studies, the current work was carried out on task design, task number, and task coverage. Two types of task designs were proposed namely, guided tasks and unguided tasks. Considering the task as a key factor, the remaining factors were also considered while employing the usability test.
