Mejoramiento del nivel de calidad de los procesos en la sección de estructuras a través de la metodología SEIS SIGMA en la fábrica de carrocerías Corporación MEGABUSS.

Abstract

The Six Sigma methodology is based on five stages; Define, Measure, Analyze, Improve and Control, a cycle called (DMAIC), the same one that was applied with the objective of identifying the sub critical processes in the producction line of the manufacture of structure for bodies, during the stage definition of the problema in which determines that Cut and Weld are the critical sub processes, because they present a high percentage of defects, the same ones that generate time loss by reprocessing;Deterioration of staff, strikes on all lines, etc. To solve these disadvantages, the initial Sigma level was determined by the defect formula per million opportunities (DPMO); Through the use of the fish diagram or ISHIKAWA the root causes of these problems were determined. Then, with the help of the matrix Analysis, Fault Effect Mode (AMEF), the defect are measured quantitatively, it is necessary to analyze the most viable solutions. Once the implementation of the enhancements to the processes was made, it was posible to show that thequalyti levelof the global was increased from a Sigma level of 1,47 to 1,68 improved, thus confirming that the improvements adopted, offer a integral solution to the presented problem, it is recommended to extend the methodology to all areas of the Company to maintain a contituous improvement.
