Findings
Motivation
Although the medical device design process has well established methods for stakeholder engagement using prototypes including usability testing (1), the front-end phases of the process lack clear guidelines for stakeholder engagement with prototypes.
The aim of this research study is to describe, in companies developing mechanical and electromechanical medical devices, the various prototypes used by design practitioners to engage stakeholders in front-end design, the stakeholders engaged, and the engagement setting

Total medical device companies: 17
Global health companies: 9
Multinational companies: 8
Stakeholders

Participants
24 interview respondents 4
Conclusions
Design practitioners in our study:
Used both 2D and 3D prototypes with various levels of fidelity in front-end design.
Emphasized the use of prototypes with end users, but also leveraged prototypes with a variety of other stakeholder types and set distinct goals to achieve with these other stakeholders. Incorporated prototypes into interviews and short design activities with little resource investment into the setting.
Findings indicate no one right prototype type, stakeholder group, and usage context, supporting the idea that these choices should be made strategically to align with articulated goals.
