Resumen

The study aligns with Sustainable Development Goal No. 12 by promoting responsible and efficient production practices within the agro-industrial sector. The objective was to evaluate the application of Lean Manufacturing methodology in optimizing the production process at a winery located in Lambayeque, Peru. The research was applied, with a quantitative approach, using a single-group pre-experimental design with measurements before and after the intervention (pre-test/post-test). The population and sample consisted of the entire production process of the winery. Data collection techniques included document analysis and observation, the instruments used for data collection were the record sheets. The intervention included the coordinated implementation of Lean Manufacturing tools, specifically the 5S methodology and the Business Model Canvas, aimed at improving operational organization, reducing waste, and strengthening the production process. Data analysis was performed using descriptive and inferential statistical techniques. Data normality was verified using the Shapiro-Wilk test, and the Student's t-test for related samples was then applied. The results showed statistically significant improvements in the production process after the intervention. The average efficiency of the production process increased from 69.15 in the pretest to 90.41 in the posttest, while effectiveness increased from 82.03 to 95.20, with significance values below 0.05. These findings indicate that the implementation of Lean Manufacturing methodologies was associated with a substantial improvement in operational performance. It is concluded that the implementation of Lean Manufacturing tools effectively contributed to the optimization of the wine production process, strengthening the efficiency, effectiveness, and operational management of an agro-industrial company in northern Peru.
