The Impact of Organizational Culture, Accountability and M&E on NGO Performance: An Empirical Analysis of the Case of South Sudan

This study empirically investigates how internal organizational mechanisms—specifically organizational culture, accountability, and monitoring and evaluation (M&E) systems—influence the performance of NGOs operating in South Sudan. As one of the most fragile states marked by prolonged conflict and weak public institutions, South Sudan relies heavily on international NGOs to provide essential services in health, education, and water supply. Despite significant inflows of foreign aid, wide performance disparities among NGOs and criticisms of weak accountability and inconsistent delivery have raised concerns. These gaps suggest that internal capacity, rather than funding levels alone, may be a critical determinant of organizational effectiveness. The research selected three international NGOs based in Juba—the Lutheran World Federation, Norwegian Church Aid, and Danish Church Aid—and surveyed 384 staff and beneficiaries. Using correlation and multiple regression analyses, the study finds that organizational culture exerts the strongest influence on performance(β= .613), followed by accountability(β= .487) and M&E systems(β= .338). Strong performance is associated with shared-value cultures, vertically and horizontally balanced accountability structures, and adaptive, learning-centered M&E systems. Theoretically, the study contributes to a growing body of research emphasizing internal factors in NGO effectiveness, especially in fragile contexts where external volatility demands robust internal resilience. Practically, it highlights strategic imperatives for NGO managers and policymakers to invest in organizational culture, institutionalize accountability, and establish data-driven learning systems. Moreover, the study aligns with the HK3.0 research agenda by engaging with the concept of Afri-cality, emphasizing youth agency and context-driven institutional innovation as key pathways toward inclusive and sustainable development in post-conflict settings.
