Abstract: Defects in Engine Assembly Line tends to occur resulting from various reasons which can be analyzed and removed with the help of six sigma. To reduce number of engine rejections, DMAIC (Define, Measure, Analyse, Improve and Control) improvement methodology is used. In define phase review; the problem is mapped by the issues causing them. In measure phase review, data is collected and process stability as well as process capability is determined. During Analyzing phase review, the causes are identified by identifying the gaps between ideal and actual process. In improvement phase review, brainstorming is done to arrive at an improvement strategy which is planned and implemented. Finally at control phase review, the control plan is validated and further opportunities are identified. The study reports the improvement in engine assembly defects reducing from 9684 PPM to 1500 PPM. The sigma level is significantly improved from 3.8 to 4.5.
