Aplicación de herramientas de gestión de la calidad para reducir costos en la empresa Quimiindustria S.A.C. Trujillo, 2023

This research aims to reduce operational costs in quality management for the company QUIMIINDUSTRIA S.A.C. It is an explanatory type of research, which explains the difference between a current situation and an improved one. Diagnostic tools used include: the Ishikawa diagram, Pareto analysis, histograms, control charts, frequency charts, and normal distribution. Subsequently, improvement tools were applied, which included: Quality Function Deployment (QFD), Failure Modes and Effects Analysis (FMEA), and DMAIC Six Sigma. The causes of losses for the company were identified as: lack of machine maintenance, lack of personnel training, lack of standardization of times, and lack of control in mixing measurements. The indicators for these issues are: the number of machine stoppages, the quantity of defective cleaning liquid in liters, the number of out-of-time products, and products of poor quality, respectively. After implementing the proposed tools, an improvement in the Z level was achieved as follows: 2.23, 1.54, 2.44, and 2.44, respectively; as a result, an annual benefit of S/12384 was obtained, with a Net Present Value (NPV) of S/5148.2 and an Internal Rate of Return (IRR) of 42.40%. Therefore, the viability of the improvement tools was determined. This is because these tools are efficient and help significantly reduce costs, increasing profitability for the company.
