This study addresses procurement challenges in Peru’s sausage industry, particularly the dependence on foreign pork suppliers and rising international prices that increase production costs. To mitigate these issues, an improvement model is proposed, integrating Lean Logistics for process standardization and the Kraljic Matrix for supplier evaluation and selection. Structural equation modeling was applied to validate the relationships between these tools and firms’ performance. The results indicate significant correlations between Lean BPM and non-financial performance (0.61), and between the Kraljic Matrix and financial performance (0.46). The implementation of the model resulted in a 27% reduction in raw material purchasing costs and a 60% improvement in operational efficiency. These findings suggest the model’s potential contribution to enhance supply chain resilience and competitiveness, while acknowledging that correlation does not imply direct causality and that generalizability may be limited by the sample size.
