This study aims to explore the impact of procurement procedures and policies on the supply chain performance in International Humanitarian Organizations (IHOs) in South Sudan. The study examines how the procurement processes within the IHOs influence the overall effectiveness, efficiency, and sustainability of the supply chain. By understanding the connection between procurement and supply chain performance, the study aims to not only to provide insights and recommendation for improving procurement practices in order to enhance the IHOs’ overall supply performance and response capacities in emergencies and humanitarian contexts, but also to find out whether or not IHOs had aligned their procurement policies, processes and procedures with their humanitarian response agenda and commitments to enhance supply chain performance. The research was guided by three main objectives that sought to determine the effect of procurement policies and procedures, the relationship between procurement procedures and policies and the challenges faced in the implementation of procurement procedures and policies on supply chain performance in selected IHOs. Data was collected using questionnaires that were administered through drop and pick later method. The study established that most of the selected IHOs have in place procurement procedures and policies that have enabled them to achieve transparency, efficiency and accountability in their operations. It was also clear that there were challenges in procurement procedures and policies on supply chain performance represented by more than 70% of the respondents. Further research on the same topic can be conducted in other organizations or UN agencies using more predictors to establish if procurement procedures and policies have impacts on supply chain performance. It is also recommended that in order to boost the performance of supply chains in humanitarian organizations in South Sudan, there is need to invest in various strategies. This therefore calls upon the management of various IHOs to follow up procurement procedures which outlines the strategies and guidelines in detail and ways of operationalization. This should be done in a consultative approach so as to smoothen the process.
