Over the years, PSI has successfully evolved a social marketing approach that is based on key principles that we believe help ensure the successful design and delivery of interventions.
To help apply these principles to our work, as well as that of program designers across the field of international development, we created the Keystone Design Framework, a simple yet rigorous approach to help apply marketing discipline to the design and implementation of public health interventions.
To find out if Keystone is right for your team’s next program, check out the Keystone Manual.
