METHODOLOGICAL CHALLENGES IN MEASURING PUBLIC SECTOR PERFORMANCE: A META-ANALYSIS OF GOVERNANCE INDICATORS IN NIGERIA
This study examines the methodological challenges associated with measuring public sector performance in Nigeria through a meta-analysis of governance indicators. The research explores the reliability, validity, and consistency of commonly used governance measurement frameworks adopted by government institutions, international organizations, and policy analysts. Despite the increasing emphasis on accountability, transparency, and efficiency in public administration, the assessment of public sector performance in Nigeria remains problematic due to issues such as inconsistent data collection, political interference, weak institutional capacity, lack of standardized indicators, and regional disparities. Using a qualitative document analysis methodology, the study reviews existing literature, governance reports, and performance assessment models to identify recurring methodological limitations affecting the accuracy of governance indicators in Nigeria. The findings reveal that many performance measurements are influenced by subjective perceptions, inadequate statistical frameworks, and insufficient integration of local socio-political realities. Furthermore, the study highlights the gap between policy formulation and implementation, which often undermines the credibility of governance assessments. The study recommends strengthening measurement frameworks, improving data systems and infrastructure, strengthening institutional capacity and autonomy, enhancing transparency and citizen participation, building a performance-oriented public service culture.
