Final answer:
To reduce defects in finished products and achieve zero defects, companies implement quality control system like Total Quality Management (TQM) and Six Sigma.
Step-by-step explanation:
To reduce defects in finished products with the goal of achieving zero defects, companies implement various quality control systems and techniques.
One such system is Total Quality Management (TQM), which focuses on continuous improvement and involves all members of the organization in quality assurance.
TQM includes processes like employee training, statistical process control, and customer feedback analysis to identify and eliminate defects.
Another system is Six Sigma, which aims to minimize defects by reducing process variations. It uses statistical analysis and data-driven methodologies to identify the root causes of defects and implement corrective actions.
