Abstract: One of the challenges of the industry of medical devices is the implementation of ergonomics and usability during the design of these products, and some constraints slow down the consideration of usability during the whole design process. For this reason, a quantification tool of the usability might aim to democratise the usability feature and facilitate the communication in design teams with limited resources during the whole design process. This proposal finds its origin in the work of a PhD thesis, of which some results are presented hereafter. A model of the tool (usability index) is proposed based on a post-task part and on a post-study part. The results have shown good trends of the usability index in terms of a correlation with System Usability Scale (SUS). Moreover, it appears that a light quantification tool of usability can be implemented in the design process to monitor and communicate about usability.

Keywords: usability; usability assessment; design processes; designer; medical devices; quantification; score; usability questionnaire.
