Applying Lean Warehousing Tools to Improve OTIF: A Case Study in a Logistics SME in the Freight Transportation Sector in Peru

The study addressed inefficiencies in the packing processes of a logistics SME in Peru, whose primary business is public road freight transportation. Warehouse practices were not properly established, affecting operational performance. Previous research has shown that Lean methodology can optimize these processes by eliminating non-value-added activities. The main challenge identified was the urgent need to reduce response time and improve packing time to meet on-time, in-full (OTIF) delivery, a key factor in customer satisfaction. The research implemented Lean tools, including 5S, Kanban, and Standardized Work, achieving significant improvements in material search time, packing time, and operator response time. The results showed an increase in OTIF from 67% to 77%, demonstrating a positive impact on operational efficiency. This study contributed to advancing the scientific literature on Lean methodologies in the context of logistics SMEs. Future researchers are encouraged to explore the implementation of these tools in other sectors and more complex contexts to maximize their potential.
