Adoption and Impact of E-Procurement on Procurement Efficiency and Supply Chain Performance in Auchi Polytechnic, Auchi, Edo State

This study examines how e-procurement adoption influences procurement efficiency and supply chain performance in Auchi Polytechnic, Edo State, Nigeria. Conceptualising e-procurement as an institutional governance mechanism rather than a mere technological tool, the study integrates technology adoption theory with public sector procurement and supply chain performance frameworks. Using a mixed-methods design, findings reveal that e-procurement significantly improves transparency, reduces procurement cycle time, and strengthens supplier coordination. However, infrastructural instability, uneven digital skills, and organisational resistance moderate these gains. The study concludes that e-procurement produces performance improvements only when embedded in supportive institutional structures and leadership-driven reforms. These insights provide policy and practical implications for public sector digital procurement in Nigerian tertiary institutions.
