Abstract
Expert evaluation methods, such as heuristic evaluation, are still popular in spite of numerous criticisms of their effectiveness. This paper investigates the usability problems found in the evaluation of six highly interactive websites by 30 users in a task-based evaluation and 14 experts using three different expert evaluation methods. A grounded theory approach was taken to categorize 935 usability problems from the evaluation. Four major categories emerged: Physical presentation, Content, Information Architecture and Interactivity. Each major category had between 5 and 16 sub-categories. The categories and sub-categories were then analysed for whether they were found by users only, experts only or both users and experts. This allowed us to develop an evidence-based set of 21 heuristics to assist in the development and evaluation of interactive websites.
