Resumen

The Peruvian commercial sector faces logistical challenges that undermine competitiveness, particularly in inventory management and delivery efficiency. Wanxin Peru, a motorcycle importer and distributor, reported a service level of 92.45%, 2.55% below the market leader's benchmark of 95%, due to inefficiencies in demand forecasting (accuracy of 88.44%) and dispatch performance (16.74% of orders delayed). This study addresses these issues through the implementation of a collaborative Sales & Operations Planning (S&OP) process, ABC analysis, and warehouse reorganization using Slotting techniques. The methodology included a systematic literature review, root cause analysis with Ishikawa diagrams and Pareto charts, engineering design, and pilot validation. Results show forecast accuracy improved to 90.27%, dispatch velocity increased from 2.21 to 2.83 orders/hour for linear motorcycles and from 1.95 to 2.35 orders/hour for three-wheelers, while service level reached 96.28%. These findings confirm that integrating S&OP and Slotting significantly enhances operational efficiency and service quality, offering a replicable framework for similar organizations in emerging markets.
