The emerging field of inclusive design has great potential to support more innovative, higher-quality design work and greater social good. However, there is still work to be done in both disseminating inclusive design, and changing the culture and practices of designers in the public and private sectors. This paper explores the question of how to increase the uptake of inclusive design. Using a qualitative meta-synthesis methodology, the author examined the current initiatives for and research on the dissemination of inclusive design, models of behaviour change and habits from psychology, as well as the cognitive habits of designers from the literature of design studies. The meta-synthesis analysis resulted in the creation of the Designer’s Behaviour Change Model, a tool to be used by inclusive design scholars and professionals to design effective interventions aimed at creating long-term, sustained change in designer behaviour, and the mainstream uptake of inclusive design methods and approaches.
