Análisis del método Kaizen como optimización de la productividad del personal en un taller automotriz : caso de estudio.

Abstract

The present research project is based on the realization of an analysis of the Kaizen methodology as an optimization of the productivity of the personnel of an automotive workshop. For the present investigation we reviewed literature about methods of continuous improvement and their impact on productivity. The Citroën Workshop of the city of Guayaquil was taken as a case study, from which the information was collected through interviews, surveys and measurement of response t imes in the vehicle entry / exit process. It was considered a sample of 48 clients who requested the service of change of oil and filter. This type of maintenance was taken since it is the one that generates greater monetary value to the brand. Statistical tools such as control charts were used to measure compliance with response times. We compared, through analytical cursograms, the performance of the workshop with the Kaizen methodology and without it. In this way, it was possible to redesign the flow chart and re-structuring the workshop process manual, reducing downtime and giving added value to the most productive activities. Finally, a projection of the profits of the workshop was carried out over a five-year horizon, in order to see if they would actually increase their sales. The results were satisfactory, increasing profits gradually, with a variation of 27%. All this was supported by the regression statistics that yielded 0.69 in the coefficient of determination R ^ 2, giving robustness and validity to the data.
