Presently, the relationship between policy and design is very much open for debate as to how these two concepts differ, relate, and interact with one another. There exists very little agreement on their relational trajectory with one course, policy design, originating in the policy studies tradition while the other, design for policy, being founded in design studies. The Special Issue has paid particular attention to the upcoming area of research where design disciplines and policy studies are exploring new ways toward convergence. With a focus on design, the authors herein present an array of design methods and approaches through case studies and conceptual papers, using co-design, participatory design and critical service design to work with policymakers in tackling challenging issues and policies. We see designers and policymakers working with communities to boost engagement around the world, with examples from the UK, Latvia, New Zealand, Denmark, Turkey, the UK, Brazil and South Africa. Finally, we offer a few reflections to build further this research area pointing out topics for further research with the hope that these will be relevant for researchers approaching the field or deepening their investigation and for bridging the academic/practice divide between design studies and policy design.
