Interview: What Is Design for Social Innovation? – UNREASONABLE.is.
Design for social innovation is really interaction design in the broadest sense; it’s interaction between people that takes responsibility for positive, systemic impact. It can take any and every physical or visible form but it inevitably begins with the invisible dynamics and forces that drive human behavior. It takes place within the communities and systems it’s working with, not outside them.
My favorite definition of a community is a group of people who care about each other more than they have to.
