Aplicación de herramientas de la calidad para reducir costos en el proceso productivo de una industria de la curtiduría en Trujillo, Perú. 2022

The objective of this research is to determine the impact of the quality management improvement proposal on the production process of a tannery industry in Trujillo, Peru. An initial diagnosis of the tannery's production process was conducted using the Ishikawa diagram, which identified four root causes for high production costs: lack of supervision in the production line, inadequate staff training, machinery maintenance issues, and raw material supply shortages. To address these problems, tools such as QFD, FMEA, and Six Sigma were employed. The improvement proposal had a significant impact, increasing the tannery's profitability and reducing production costs, preventing production stoppages, and enhancing the quality of the leather production process. The feasibility of the improvement proposal was supported by an economic evaluation, resulting in a NPV of S/ 502,114.64, an IRR of 97.96%, and a payback period of 3.2 years, equivalent to 4 years. It was concluded that the implementation of this improvement proposal in the production process is highly beneficial for the tannery, improving its efficiency, quality, and profitability.
