Implementation of SPC tools for process Improvement: A Case Study

The main objective of this paper is to draw Pareto chart and cause and effect diagram for automotive components; using statistical process control and their tools. The Pareto chart gives us the percentage of different product defects. The quality and productivity of products may be improved by applying various quality tools. Over last decade; the level of significance on SPC analysis has been considerably increased but the literature findings reveal the importance of understanding the concepts, critical assumptions and methodologies; while implementing in various manufacturing process. It is found that the defects in crank shaft bearings are a very serious issue which leads to the wastage of money and time of industry.
