Abstract

Usability is a key consideration when developing an interactive software application because of the various outcomes it can produce. Accordingly, numerous evaluation methods have been proposed, however, a recent review of usability methods concluded there is no current consensus on models applied to usability. While questionnaires are a commonly used measure, it is unclear which questionnaire(s) are most appropriate for a given context, so new usability researchers face confusion over which to select. To aid questionnaire selection, the appropriate type (post-study or post-task), general structure and content, specific advantages and disadvantages, aspects of usability covered, and psychometric quality should be considered. This paper presents a literature review and analysis of general post-study and post-task usability measures. Questionnaires are weighed up and discussed on each aspect, so practitioners can gain a holistic overview and identify relative strengths of individual questionnaires within their questionnaire type. Overall recommendations and specific questionnaire suggestions are provided for guidance, along with how future research can expand the review.
