Abstract The main objective of this paper is to conduct process capability analysis for abnormal sound of compressors of a refrigerator; using statistical process control and their tools. The process capability gives us the three different views of capability measures. The normal curve is applied generally on the product's percentage which is out of specification. Process capability indices are calculated to provide single number assessment of the ability of a process to fulfil the specification limits on quality characteristics of interest. Thus; the quality and productivity of products may be improved. Over last decade; the level of significance on process capability 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 sound of compressor of the refrigerator is an important cause of rejection; which leads the wastage of money and time of industry.
