Explain Quality assurance in Quality control

Quality assurance and quality control are two important aspects of ensuring the overall quality of a product or service. While they are related, they have distinct roles in ensuring quality.

Quality assurance is the process of setting and maintaining standards for a product or service, and ensuring that these standards are consistently met throughout the production or delivery process. This involves creating and implementing processes and procedures to prevent defects and errors from occurring in the first place. Quality assurance is a proactive approach to quality management, focusing on preventing issues before they arise.

On the other hand, quality control is the process of inspecting and testing products or services to ensure that they meet the established standards for quality. Quality control is a reactive approach to quality management, focusing on detecting and correcting defects or errors after they have occurred. This may involve conducting inspections, tests, and audits to identify and address any issues that may affect the quality of the final product or service.

In essence, while quality assurance focuses on preventing quality issues, quality control focuses on identifying and correcting them. Both are essential components of a comprehensive quality management system and work together to ensure that products or services meet the expectations and requirements of customers.
