Pact Vietnam has launched an organizational capacity building strategy to help strengthen local organizations in a sustainable way. The strategy is assessment-based, peer-connected, demand-driven, and customized. It uses Pact's globally recognized Organizational Capacity Assessment methodology which involves a participatory self-assessment, action planning, and monitoring progress over multiple years. By addressing both technical and organizational capacities, Pact aims to develop more viable local organizations that can better manage health issues independently in the long run. Key challenges include balancing customization with reach and ensuring local buy-in for capacity building.
