The Designing Policy Toolkit is the result of a research project conducted over one year by Laura Forlano and Anijo Mathew, assistant professors at the Institute of Design at Illinois Institute of Technology, and funded by the Urban Communication Foundation. Forlano and Mathew held a series of workshops focused on urban technology in three major metropolitan centers in the United States: Chicago, New York, and Boston. The workshops engaged a range of stakeholders, from policymakers and entrepreneurs to activists and academics, in hands-on activities using open and participatory codesign methods. This toolkit illustrates the ways in which urban technologies are embedded with values, as well as how codesign methods enable diverse stakeholders to come together around the complex sociotechnical questions that are shaping everyday life in cities.
