Purpose of the study: The purpose of the study was to explore the impact of Supply Chain Technologies on the performance of Inter-Governmental Organizations (IGOs) in Nairobi City County. The study was based on pivotal role of supply chain management in contemporary global economies and the need for automation to meet the demands of modern organizations. Short introduction of problem statement: IGOs face significant inefficiencies due to outdated supply chain processes, resulting in high operational costs, delays, lack of transparency, and resource misallocation. These challenges hinder their ability to deliver services effectively and meet stakeholder expectations. The study seeks to address these inefficiencies by examining how supply chain technologies can enhance IGO performance. Method/methodology: The study employed a descriptive research approach, targeting IGOs in Nairobi City County through a census approach due to the limited population size. Data collection involved a self-administered questionnaire, and a pilot study ensured reliability and validity. Data analysis included both quantitative and qualitative methods. Results of the study: The findings revealed that all supply chain technologies—Electronic Procurement Systems, Inventory Management Systems, Information Management Systems, and Transport Management Systems—positively and significantly impact the performance of IGOs in Nairobi City County, Kenya.Conclusion and policy recommendation: The study concludes that adopting these technologies is crucial for achieving operational efficiency, cost-effectiveness, and improved service delivery. Recommendations include investing in comprehensive e-procurement and inventory systems, integrating IMS with collaborative tools for enhanced data access, and maximizing TMS functionalities for route optimization and shipment tracking. These strategic implementations will enable IGOs to operate more effectively in a complex global environment, ensuring better resource utilization, cost control, and service delivery.
