USAID Advancing Nutrition and Breakthrough ACTION applied two user-centered design approaches to find new solutions to common nutrition challenges:

1. Behavioral design applies behavioral science to understand how people interact with their environment and each other under different conditions and builds solutions from these insights.
2. Human-centered design centers users’ perspectives in all parts of problem solving to meet their needs.

This guide describes how we used these approaches to identify ways to improve child feeding during and after illness and children’s dietary diversity through community health worker counseling.
