Which aspect of quality focuses on the ability to reduce defects in products or services?

The aspect of quality that focuses on the ability to reduce defects in products or services is quality control. This process involves monitoring and managing production processes to ensure that the final output meets the required standards of quality. Quality control typically includes inspection, testing, and the evaluation of products and services to identify any deviations from quality standards, allowing for corrective actions to be taken before products reach the customer.

Quality control is integral to maintaining high levels of consumer satisfaction and minimizing waste, as it directly addresses the occurrence of defects and aims to enhance the overall reliability and performance of the product or service. Through effective quality control measures, organizations can significantly reduce variability and defects, thus improving their operational efficiency.
