Incidencia de la certificación ISO 9001 en los indicadores de productividad de las industrias manufactureras de la ciudad de Guayaquil.

Abstract

This research article includes a study carried out in the city of Guayaquil, in which the main productivity indicators of companies certified with ISO 9001 were analyzed. For this, a sample of twenty five certified companies was taken. The information was obtained through a recognized city certifier and contrasted with the data published in the Superintendence of Companies. Subsequently, a multivariate discriminant analysis of the data was carried out, having previously carried out the verification of the assumptions necessary to perform it, applying the Shapiro-Wilk tests and the Box M test. The results of the classification in the membership groups show that 76% of the grouped cases were correctly classified. The results obtained in the percentage variations of the indicators show that the indicators with the greatest variation are IP2 (Operating profit ratio / value added) and IP3 (Net profit ratio / value added) showing a significant improvement, thus checking the incidence of ISO 9001 in productivity.
