Impacto de la calidad en la rentabilidad Jairo Antonio Forero Luz Esperanza Bohórquez Alfonso Lozano Ingeniería Calidad Estrategia Rentabilidad Ventaja Competitiva La calidad se ha constituido en una de las herramientas gerenciales de mayor utilización en las organizaciones, por cuanto se parte de la premisa, que genera impacto positivo en el desempeño financiero de la empresa. Sin embargo y a pesar de la anterior consi- deración, es común encontrar en el mercado, empresas que posterior a implementar la estrategia de la calidad, no logran impactar las finanzas de la organización, y peor desapare- cen de mercado. El propósito del articulo es analizar los diferentes estudios académicos realizados acerca de la relación calidad - rentabilidad, y a la luz de estos concluir de manera preliminar si la calidad influye o no, en el desempeño financiero de la organización, al igual que identificar, los factores que determinan dicho impacto. Algunos estudios demuestran que existe un impacto positivo de la calidad para la organización, otras investigaciones afirman que la calidad no es rentable pero sí necesaria y finalmente otras aseveran que éste impacto, solo es posible a través de la estrategia de negocio. En general los resultados son interesantes y deben ser analizados por el sector empresarial, si se desea que la calidad realmente impacte la rentabilidad. 2008 artículo científico 0121-750X https://www.redalyc.org/articulo.oa?id=498850166007 es http://www.redalyc.org/revista.oa?id=4988 Ingeniería application/pdf Universidad Distrital Francisco José de Caldas Ingeniería (Colombia) Num.1 Vol.13
