Aplicación de las Herramientas de Gestión de la Calidad para mejorar la producción de la empresa Trupal S.A. Trujillo – La Libertad, 2023

This research work aims to determine the impact of Quality Management tools on reducing surcharges to increase production at the Trupal S.A. company in the city of Trujillo, Peru. It begins with a diagnosis of the company's production areas using tools from Statistical Quality Control and cost estimation of losses. It concludes with the implementation of an improvement proposal using Quality Management tools and the resulting improvements are determined. Four root causes were identified for the surcharge problems: Lack of staff training, lack of production line planning, improper procurement of raw materials, and lack of machinery maintenance. After quantifying the root causes, the surcharges amount to S/ 205,789.00 soles. By implementing the improvements resulting from the Quality Function Deployment (QFD) with its Quality House, recommendations from Failure Mode and Effects Analysis (FMEA), and the DMAIC Six Sigma methodology, the loss due to surcharges decreased to S/ 123,472.00 soles. Therefore, the application of Quality Management tools to improve production at the Trupal S.A. company generated a benefit of S/ 82,317.00 soles.
