Standardised Questionnaires in Usability Evaluation. Applying Standardised Usability Questionnaires in Digital Products Evaluation

The usability evaluation plays a crucial role in the human-computer interaction. It is one of the basic elements used to verify the user interface quality and also, the quality of the system, as a whole. The goals of usability testing can vary by study, but usually they include: identifying problems in the design of a product or service, uncovering opportunities to improve, learning about the target user’s behaviour and preferences. In this paper, we will present an analysis over the most commonly used standardised questionnaires. Also, based on a comparison between them, we will present the results of an analysis done by a group of students, who were asked to compare and decide which standardised questionnaire would be appropriate for their usability evaluation over a certain project. The students were split in teams, each team having a different project to analyse. Their activity is part of the “Interactivity and Usability” subject of Multimedia Technologies Master Degree Program of Politehnica University of Timișoara. We will also present a score of choosing some of the surveys and emphasise the pros and cons of the preferred questionnaires.
