Nonconforming product control is a critical element of quality management systems that ensures products or services not meeting specified requirements are identified, controlled, and properly managed to prevent unintended use or delivery.
Effective nonconformity management protects product quality, maintains customer satisfaction, and drives continuous improvement through systematic problem resolution and prevention.
