This brief presents a health-sensitive conceptual model and typology of fragility, with the aim of improving MOMENTUM’s understanding of fragility and how it impacts health and, in turn, strengthens health programming. The conceptual model and typology proposed here are intended as internal guidance for USAID and USAID partnerships/projects and are designed to inform fragility assessments and contextual analysis as well as monitoring, evaluation, & learning approaches, conflict sensitivity, and exit strategies.
