Resumen

The objective of this study is to assess the impact of Lean Manufacturing tools on the efficiency of a laboratory within a production company located in Lima. To this end, a total of 16 weekly records from the pre-test stage (from November to February) and an additional 16 records from the post-test period (from July to October 2025) were reviewed. The research was characterized by its applied nature, employing a quantitative approach, an explanatory level, and a pre-experimental design. Information was collected using record formats and checklists. The findings indicated significant enhancements after the implementation of the 5S and Poka-Yoke methodologies. The total efficiency of the system increased from 56%. The percentage increased from 45% to 86.41%, indicating a substantial rise of 53.06%. Concurrently, there was a 15% increase in the efficiency of material usage. 24% of the labor force by 15. The efficiency of the teams was found to be 87%, which is a 14% increase from the previous year. The observed discrepancy, which amounted to 10%, was primarily attributable to a reduction in downtime. The hypothesis was analyzed, yielding a significance value of 0.00. This finding serves to reinforce the conclusion that the implementation of Lean Manufacturing practices is conducive to enhancing the efficiency of the laboratory.
