Impacto de la Gestión de calidad en la productividad, una perspectiva desde la norma IATF-16949

Abstract

The objective of this research is to analyze the implications on the level of productivity in a prototype company of the automotive electrical sector on the occasion of the adoption of the IATF-16949 standard. The company studied is one of the three companies that make up section 335920 of the Classification System for North America (INEGI, SCIAN, 2018) corresponding to the manufacture of electrical conduction cables for the automotive industry. The methodological strategy is quantitative, correlational in scope and experimental design; it was developed from a comparative analysis through an analysis of variance (ANOVA) with a significance level of 95% (α=0.05) for the indicators level of waste (ND), operational availability (DO), compliance with specifications (CE) and on-time deliveries (ET), all measured from the organizational productivity base. The analysis criteria correspond to indicators measured in the plant, through the Quality Function Deployment (QFD), their impact was grouped and weighted in a global productivity index (GPI). Among the main findings, it was corroborated that a quality management system linked to control tools under the automotive standard IATF-16949 contributes on productivity organizational improvement and to the increase of the General Productivity Index (GPI), a condition that favors the detection, prevention and treatment of critical control points in all phases of the process.The objective of this research is to analyze the implications on the level of productivity in a prototype company of theautomotive electrical sector classified in section 335920 of the Classification System for North America (INEGI, 2018),due to the adoption of the IATF-16949 standard.

El objetivo de esta investigación es analizar el impacto en el nivel de productividad en una empresa prototipo del sectoreléctrico automotriz clasificada en el apartado 335920 del Sistema de Clasificación para América del Norte (INEGI, 2018),con motivo de la adopción de la norma IATF-16949. La estrategia metodológica es cuantitativa, se desarrolló a partir deun estudio comparativo mediante un análisis de varianza con un nivel de significancia del 95% (α=0.05) para los indicadoresde desperdicio, disponibilidad operacional, cumplimiento de especificaciones y entregas a tiempo. Entre los principaleshallazgos, se corroboró que un sistema de gestión de calidad vinculado a herramientas de control bajo la norma automotrizIATF-16949, mejora la productividad organizacional e incrementa el Índice General de Productividad, condiciónque favorece a la detección, prevención y tratamiento de los puntos críticos de control en todas las fases del proceso.
