Examining the Effect of Policy Evaluation Practices on the Performance of Public Institutions in South Sudan

Abstract

This study examines how policy evaluation practices influence the performance of the Ministry of Defence and Veteran Affairs in South Sudan. The Ministry faces significant recruitment and selection challenges due to limited infrastructure, resources, and a developing education system, challenges that are intensified by the country's post-conflict environment. To explore these issues, the research employed a mixed-methods approach, combining quantitative surveys with 342 respondents (response rate: 85.9%) and qualitative data from 30 key informant interviews using semi-structured protocols. The theoretical framework integrated Institutional Theory, which explains how organisational norms shape policy practices; Policy Implementation Theory, focusing on the processes affecting policy delivery; and Resource Dependency Theory, highlighting how resource constraints influence organisational behaviour. These theories guided the development of measurement tools and interpretation of results, especially regarding the impact of institutional and resource factors on policy evaluation effectiveness. Quantitative analysis using regression modelling at a 5% significance level (p<0.05) revealed a strong positive correlation (r = 0.692) between policy evaluation practices and organisational performance, with an R² of 0.479. This indicates that nearly 48% of performance variability can be explained by the extent of policy evaluation efforts. The findings emphasise the crucial role of systematic evaluation mechanisms in enhancing organisational outcomes. The study recommends strengthening policy evaluation frameworks, investing in education and infrastructure, establishing regular monitoring and feedback systems, and enhancing capacity building for personnel involved in policy evaluation. Additionally, stakeholder engagement and performance-based incentives are suggested to further improve policy impact. Future research should explore how contextual factors such as post-conflict recovery, political stability, and external support influence policy evaluation effectiveness. Overall, this research provides empirical evidence supporting systematic policy evaluation as vital for improving organisational performance and stability in fragile states like South Sudan.
