The document outlines a six-year research project in Sierra Leone focusing on performance-based financing (PBF) and its complex implementation journey from 2009 to 2017. It analyzes various contextual factors, including agency, structural features, and framing processes, that influence the PBF policy process. The findings suggest that narrative framing, power dynamics, and historical legacies are critical in shaping PBF outcomes and call for flexible approaches to foster political support and sustainability of reforms.
