Resumen

The Peruvian footwear retail sector faced persistent difficulties in meeting On Time In Full (OTIF) deliveries, affecting customer satisfaction and operational efficiency. Although prior studies explored Lean tools, few addressed their integrated application in SME warehouse environments, revealing a gap in the literature. This study proposed a Lean model combining 5S, Standard Work, Kardex registration, and multi-Criteria ABC analysis to address warehouse delays, inventory inaccuracy, and spatial disorganization. After implementation, OTIF increased from 71.67% to 87.76%, inventory accuracy improved by 16%, and the cost-benefit ratio reached 16.12. These results demonstrated substantial gains in operational performance and service reliability. The study contributes a replicable framework for optimizing warehousing processes in resource-constrained contexts. Its practical implications suggest that small retail enterprises can enhance competitiveness and customer experience through adapted Lean strategies, without requiring major capital investments. The findings encourage further exploration of Lean applications tailored to the logistics needs of Latin American SMEs.
