The Intervention Design stage is where science meets art and where Small Changes can deliver Big Results. Interventions target very specific behaviors (or a series of micro behaviors) and often incorporate multiple behavior modification techniques. Importantly, while interventions must succeed at closing behavioral gaps, they must also be acceptable to both the designer (i.e., the intervention sponsor) as well as the consumer (i.e., the intervention target). These considerations serve as core inputs into the intervention design process.
