Comparative Usability Task Measurement (CUE-8)

You can’t manage what you can’t measure - but can you manage measurements to generate reproducible and useful results? This workshop compares practical approaches to usability task measurement. Participants will carry out independent, simultaneous measurements of a website ahead of the workshop. At the workshop we will compare results.

About the Workshop

As usability specialists start working professionally with task measurements they quickly realize that measuring usability is more than buying a stopwatch and computing average task times using a spreadsheet.

Recent discussions in usability discussion forums have shown that there is little knowledge and agreement on what constitutes best practice in usability task measurement. This workshop will assemble a number of experienced professionals to discuss the state-of-the-art in usability task measurement based on a common experience in measuring a particular website. To the best of our knowledge, nothing like this has ever been done before. The seven successful Comparative Usability Evaluation (CUE) studies that have been conducted until now (http://www.dialogdesign.dk/cue.html) have focused on qualitative usability evaluation methods such as usability testing. The proposed workshop is the first comparative study of quantitative methods.

Before the workshop, all participants — including the organisers — will carry out independent, parallel measurements of a website using the same test tasks, which all participants will have a chance to comment on before the measurements start. The target group for the website will be the general public. Participants must be willing to spend 10-30 hours on these professional task measurements before the workshop. Each participating team must submit an anonymous measurement report to the organisers before the workshop.

Participants should be willing to measure and report task performance using common operationalized metrics of ** Effectiveness — for example, completion rate and errors ** Efficiency — for example, time on task ** Satisfaction — for example, post-task and post-test ratings. Participants who don’t normally do post-task satisfaction or post-test satisfaction, should consider using the System Usability Scale (SUS) as a post-test questionnaire.

The Agenda for the workshop is: ** Introduction ** Each team presents their approach ** Results of preliminary analysis of the measurements ** Discussion: Lessons learned. What is the state-of-the-art?` ** Conclusion - Further work

This workshop presents a unique opportunity for participants to compare their measurement and evaluation skills to those of their peers and learn from the differences.
