Abstract: 6-Sigma is a quality tool that measures how far a given process deviates from the perfection. It is considered as the one of the most efficient quality tool so far on the globe, which produces the product with approximately zero defects. Sigma level determines the quality performance of a product, service delivery or a process and provides an overall framework for continuous improvement in the process of an organization. The sigma level can be calculated using the DPMO (Defects Per Million Opportunities) which is a measure of the number of defects occurring in a process. This paper deals with the application of the 6-Sigma methodology in determining the performance level of various failures that occurred in the Load Hauling Dumpers used in open cast mines. DPMO, RPN can fairly determine the machine behaviour. This paper throws some light on establishing the relation between the 6-sigma quality and risk priority number so as to estimate the behaviour of the equipment.
