Co-design: Methodologies for Investigating, Developing and Sharing Knowledge in View of New Solutions for Future Use

International audienceThis chapter lists the sciences, methods and techniques implemented. It brings together the scientific domains used most often to observe, understand and implement co‐design, in particular sociology and ergonomics, as well as anthropology. The ergonomic approach for healthcare technologies depends on an initial, fundamental stage: analyzing the usage context of the technology or tool involved during its design. The chapter illustrates the potential contribution of design thinking. The tools for qualitative analysis are therefore classically used in co‐design: focus groups, affinity diagrams, open, semi‐structured or closed interviews, creativity methods, observation, and life stories and shadowing. Specifically, the chapter develops the idea of the scenario, which is an ambivalent and useful concept; it is certainly sometimes disputed in its ambition to represent the roles that interact around a yet unspecified future solution, whose uses, nonetheless, remain largely unpredictable. It presents the relationship between co‐design and technology research
