The worlds and modalities of engagement of design participants: A qualitative case study of three medical innovations

Individuals with different backgrounds such as engineering, medicine, industrial design, business, healthcare management and computer science often contribute to the design of a medical innovation. But how do such heterogeneous design participants actually combine their expertise to develop a medical device? Adapting Bucciarelli’s concept of “object worlds”, which recognises that those who contribute to a design process inhabit different worlds and see the object of design differently, this paper examines the perspectives of 8 design participants who contributed to the design process of three Canadian medical devices. In-depth analyses of semi-structured interviews clarified what design participants saw through their particular “lens”, how their responsibilities, knowledge and motivations combined and how they engaged into the design process.
