In response to the evident need for building up the supply chain management workforce, the USAID Bureau for Latin America and the Caribbean provided financial support to CapacityPlus to enhance capacities in Central American countries. The project coordinated a regional HIV/AIDS Commodity Security Workshop to share and apply lessons learned from USAID’s ten-year Latin American contraceptive security work and from specific health workforce and supply chain work already done in the region. Additionally, workshops focusing on supply chain workforce motivation and quality of services were held in the Dominican Republic and El Salvador. Building on the action plans developed at its workshop, El Salvador sought to delve more deeply into ways to systematically improve the quality of services through supportive supervision. This technical report reviews the actions taken and lessons learned in strengthening and professionalizing the supply chain workforce.
