Step-by-step explanation:
Quality control and quality assurance are two essential concepts in the field of product and service quality management.
Quality control refers to the set of measures taken to ensure that the final product or service meets the required standards of quality. It is a reactive approach that involves detecting and correcting defects in the product or service during or after production. Quality control is concerned with the inspection, testing, and sampling of products or services to ensure they meet the pre-established quality standards. It mainly involves the measurement of product or service attributes and comparing them to the desired levels.
On the other hand, quality assurance is a proactive approach that focuses on preventing defects before they occur. It is a systematic and comprehensive process that involves developing and implementing standards, procedures, and policies to ensure that the product or service meets the required level of quality. Quality assurance focuses on the entire production process, from the planning and design stage to the final product or service delivery. It involves continuous monitoring of the production process, identifying areas that may cause defects, and implementing corrective actions to prevent them from happening.
In summary, quality control is concerned with detecting and correcting defects in the product or service, while quality assurance is focused on preventing defects from occurring in the first place by implementing effective processes and procedures. Both approaches are critical in ensuring that products and services meet the required level of quality and customer satisfaction.
