Nepal has a long tradition of designing good multisectoral nutrition policy. However, success of policy implementation has varied. More evidence on how to successfully carry out multisector nutrition policy is needed. This study used a mixed-method longitudinal design to track qualitative and budgetary changes related to MSNP processes nationally as well as in 3 districts. Qualitative changes in each study area were assessed through interviews, observation, news content, and meeting notes. Changes in allocations and expenditures were calculated based on budget documents, work plans, and validation interviews.
