As a discipline, intervention design is less well defined and this is perhaps because many intervention designers focus on being, as examples, user experience designers, service designers, and product designers. Some designers even report (anecdotal) conversations whereby a non-designer has expressed exasperation for taking so long to design an intervention, when they feel the crucial thing is to just get it out there and get people using it. Despite successfully envisioning future models of inter- and trans-disciplinary collaboration, the research highlighted that notions of identity, collegiality, and protectionism continued to reinforce the siloed institutional structure. However, designing the conditions for successful collaboration in academia requires the discipline to move beyond methods and consider its role within the academy. The chapter also presents an overview on the key concepts discussed in this book.
