Supply chain management (SCM) practices have become strategic resources and capabilities for enhancing both competitive advantage logistic performance (ORGPER). However, it is not clear how SC Practices influence logistic performance in the agribusiness context. However, the mechanism of SCMPs effects is not yet understood since extant literature has produced mixed results. Hence, this study sought to test the impact of mediation of the competitive advantage of relations between SCMP and Reperform the point of view of Kenya's dairy supply chain. The study examined four estimates that were tested using partial minimum square structural equation modeling (PLS-SAME) techniques to work out the purpose of the study. Across-departmental survey design has been used to collect preliminary data from109 dairy cooperatives in thirteen major dairy producing counties in Kenya. The results reveal that SCM practice has a positive and significant effect on CA(P=0.730) and ORGPER (P=0.237). In addition, THERE is a positive, statistically significant effect on THECAORGPER (P=0.522). Further results show that CA mediates the relationship between SCMP and ORGPER. Consequently, the study concludes that SCMPs first generate CA, which in turn enhances ORGPER in a logistic sense. Theoretically, the study provides insights on the resource-based view theory as well as a conceptual framework for its validation. Similarly, the study informs managers and policymakers in knowing specific SCMPs to focus on to enhance CA and ORGPER of the dairy cooperatives in Kenya.
