By reducing the defect rate, Matsushita can realize the benefits in following aspects.
-Raw Material & Man-hour: Every product required raw material and man-hour to be manufactured including the defect one. However, the defect product cannot be sold to customer, causing the used raw material and man-hour to be wasted. By reducing the defected, less raw material and man-hour will be wasted, helping increasing the productivity and the bottom line of the company.
-Reputation : manufacturing process with higher defect rate tends to unintentionally leak the defect product to customer, causing the customer dissatisfaction which will damage the brand and reputation of company.
