Sustainable Development using Six Sigma in Automobile Industry

This report shows the step-by-step application of the Six Sigma DMAIC methodology to eliminate the defects in a VE pump assembly process of an automotive company. This has helped to reduce defects in the process there by improve productivity and on time delivery to customer. During the Measure and Analyse phases of the project, data were collected from the processes to understand the baseline performance and for validation of causes. These data were observed through various graphical and statistical analyses. The statistical processing of data revealed that a relationship does exist between number of defects and total break down time and that 76.4% of defects are related to maintenance practices and wear issues. This can happen if, for instance, we produce both work orders and job guidelines of improvement type during the implementation the Improve and Control phases.
