To Analyze the Use of Statistical Tool/S for Cost Effectiveness and Quality of Products

Companies can lose money because they fail to use significant opportunities to improve product quality as well as product cost. In order to survive in a competitive market, reduce cost of product by improving the quality and productivity of product is must for any company. The objective of this study is to provide system/instructions and methodology to reduce cost of product by implementing statistical tools in local plastic injection molding company. Injection molding Company deployed some part of the “Seven Basic Tools” to improve the quality of the product used by our society and reduce cost of the product. Companies may reluctant to their quality status and customer satisfactory status without implementing any helping tool which may reduce cost by identifying and decreasing number of defects and consequently improving product quality and productivity of the system/process. Statistical techniques like “Seven Basic Statistical Tools” (SPC) provides a very valuable and cost effective way to meet these objectives. The principle aim of this study is to train quality personnel that how to use these SPC tools and exploit these data in Pareto analysis, control Chart, Cause & Effect Diagram and histogram analysis. The causes of nonconformity and root causes of quality problems were specified and possible remedies were proposed to organization to overcome their problems. Some significant Improvement was also observed after SPC implementation in Process potential capability (Cp), Process Actual Capability (Cpk) and Defective parts per
