This document discusses aligning health programming using behavioral outcomes to improve impact and coordination. It argues that intervention-driven programming can dilute impact by creating silos and lack of shared accountability. A behavior-centered approach focuses investments on integrated strategies to change key behaviors that drive issues like maternal and child mortality, such as seeking care for pneumonia or using modern contraceptives. This approach must be applied at all levels from donor portfolios to implementing partner projects. It promises increased coordination, shared accountability, and adaptive management among implementing partners.
