Resumen

This study aimed to implement total quality management (TQM) to reduce non-conforming products in a footwear microenterprise (MSME) in Trujillo. The research employed a quantitative, applied-level approach with an explanatory scope and a preexperimental pretest-posttest design. The population consisted of all products manufactured by the MSME, with the sample being those with the highest incidence of non-conformity. Data collection was conducted through direct observation and document review, using an observation guide and a data collection form over a period of 22 working days. Initially, activity and flowcharts were used to analyze the production process and determine the percentage of non-conforming products, which was 12.25%. Subsequently, TQM tools were applied, such as Ishikawa and Pareto charts, brainstorming, statistical process control, PDCA cycle, and Hoshin Kanri, all geared towards continuous improvement and process standardization. As a result, the percentage of non-conforming products decreased to 4.09%, representing an 8.16% reduction. Inferential analysis using the Wilcoxon test (p < 0.001) confirmed that the observed reduction is statistically significant. It is concluded that the implementation of total quality management has a positive effect on reducing nonconforming products in a footwear micro-enterprise.
