The Cost of Poor Quality (COPQ) is a critical metric used in quality management to quantify the costs associated with not producing a quality product or service. This includes costs resulting from failures that occur both internally, such as scrap, rework, and wasted materials, and externally, like warranty claims, returns, and lost customer goodwill.

By focusing on the total cost of failures, both internal and external, this metric provides a comprehensive view of how inadequate quality impacts the organization financially. It helps businesses identify areas for improvement and assess the potential return on investment for initiatives aimed at enhancing quality. This holistic view of costs facilitates informed decision-making regarding process improvements and customer satisfaction strategies.

Other choices, while related to quality, do not encapsulate the entire spectrum of costs associated with poor quality. The investment in process improvements, customer complaints costs, and quality audits each represent specific areas of quality management but do not address the overall financial impact stemming from failures in quality across the board.
