Abstract: The study evaluates the effects of digitalization on the efficiency of supply chain functions in the retail sector of Tanzania, specifically focusing on the Azam Bakhresa Group. As technology advances, retail supply chains face increasing demands to incorporate innovations like artificial intelligence, blockchain, the Internet of Things (IoT), and electronic procurement systems, such as TANePS. The research aims to evaluate how these technologies affect supply chain transparency, efficiency, responsiveness, and overall customer satisfaction in the Tanzanian context. Utilizing a descriptive research design and a mixed-methods approach, the study drew data from 80 respondents, including supply chain professionals, IT specialists, procurement officers, and retail managers, through questionnaires and in-depth interviews. The quantitative data were analyzed using descriptive statistics, while qualitative responses were thematically analyzed to provide depth to the numerical findings. Results indicated a strong consensus on the positive impact of digital tools. Over 95% of respondents recognized that emerging technologies enhance supply chain visibility, accountability, and responsiveness.
