Application of Lean Tools to Improve Productive Times in Workers of a Company in the Automotive Sector, Lima, 2024

Abstract

The automotive sector plays a critical role in economic development, but service companies face efficiency challenges that limit their competitiveness. This study aimed to apply Lean tools to optimize production times in a company dedicated to vehicle technical inspections in Lima. The research was applied, with a quantitative approach and a pre-test-posttest experimental design, developed during an observation period of four months. The data were obtained through chronological records and direct observation, implementing the 5S, Work Standardization (EdT) and Just-in-Time (JIT) tools. The results showed a significant reduction in standard care time, from 20.90 to 17.42 minutes, representing an average improvement of 3.48 minutes. The difference was statistically significant according to the Wilcoxon test (p = 0.003). It is concluded that the application of Lean tools effectively contributes to the improvement of productivity and operational efficiency in the Peruvian automotive sector.
