Traditionally, designers have focused on enhancing the look and functionality of products. Now they are using design tools to tackle complex social issues—to find ways to provide low-cost health care, implement clean water systems, distribute mosquito nets, and get out the vote. In this audio lecture, sponsored by the Stanford Social Innovation Review, Jocelyn Wyatt, social innovation lead at the award-winning consultancy IDEO, describes her organization’s efforts in Asia, Africa, and Latin America to use design thinking, a problem-solving system that is grounded in a client’s or costumer’s needs. Design thinking, with its focus on local expertise to uncover local solutions, allows high-impact solutions to bubble up from below rather than being imposed from the top. It provides both a way to create and sustain broader social inclusion.
