Making Usability Test Data Actionable! A Quantitative Test-Driven Prototyping Approach
Felix Kretzer, Alexander Maedche · 2023
In recent years, the availability and use of prototyping and usability testing tools has increased massively in practice. In parallel, research introduced multiple novel approaches and tools to assist novice and expert designers in prototyping. However, existing research has not looked into how to assist designers in conducting usability tests and making the collected quantitative data directly available in prototyping tools. In this paper, we distill three design goals from literature and propose a novel quantitative test-driven prototyping approach. The approach in its current form consists of a process and two user interface artifacts supporting selected actions of our process. We conducted a formative study to gather feedback from potential users on our approach. We use the collected feedback to refine our approach, identify trade-offs, and propose future research directions. We contribute by providing a novel quantitative test-driving prototyping approach that tightly connects prototyping with asynchronous usability testing.
