Quality management decreases production costs because the sooner a defect is located and corrected, the less costly it will be in the long run [7]. With the advent of automated testing tools, although the initial investment can be substantial, the long-term result will be higher-quality products and reduced maintenance costs. The total cost of effective quality management is the sum of four component costs: prevention, inspection, internal failure, and external failure. Prevention costs consist of actions taken to prevent defects from occurring in the first place. Inspection costs consist of measuring, evaluating, and auditing products or services for conformance to standards and specifications [9]. Internal failure costs are those incurred in fixing defective products before they are delivered.
