Community Buy-in: Generating passion to solve community problems is a tenet of both design thinking and public health. When community members assemble together to tackle problems, the power of mobilization and local solutions begins to take place. Such grassroots efforts are typically more sustainable than top–down strategies employed by experts with little community involvement. Public health practitioners who are committed to community mobilization have learned to balance the use of best practice evidence while allowing for local innovation and creativity (34, 35). While community buy-in has been successfully implemented in recent health interventions (36, 37), successful long-term assessment is uncommon.
