Co-designers are community members that we partner with to collectively advance the design of a solution. Having co-designers conduct research or test concepts within their own communities is an excellent way to strengthen your design process. Community co-designers usually have good insight on how to recruit research participants, and where and when to conduct interviews. They’ll also have an existing sense of what it is their community needs, so they will be able to ask critical questions that build on what’s already known. It’s helpful to have established relationships with a cohort of co-designers when using this method.
