Impact Employing of Six Sigma Methodology onto Poor Quality Costs

Dr. Zuher Hassan Abdullah and Dr. Saadia Haief Kadhum

Six sigma is a methodology to solve problems before the design team begins actual development and works to demystify the design process. It also works to link the highest quality and the lowest production costs or services. This method is applied to all stages of production or service and not only to the final product, which contributes to the development production processes and reduce mistakes that can reduce production defects. This research aims to improve production quality by increasing sigma level up to six sigma to one company inside the country after identifying the sigma level is depended from to this company. The actual cost indicator has been employed since balancing quality costs is very important in controlling on these costs and trying to reduce or eliminate them. The production indicator has been used because reducing defects in production to a minimum helps to improve quality, reduce of poor quality costs and achieve customer satisfaction. The application of this methodology has a significant impact to increase financial savings and reduce number of defects during technological path to manufacture variety products on the same path and thus reduce failure costs. Statistical equations and techniques were employed to control the production processes by determining the sigma level adopted in the company and observing the effect of adjusting sigma level on the production quality. The integration results of methodology phases showed that the product( P1) achieved the highest level of quality as it has the largest level of Sigma (3.45), and the application of advanced levels of sigma in the company contributes to reduce the number of defects, and poor quality costs to a minimum.
