Quality Assurance vs. Quality Control

Quality assurance and quality control are two important aspects of quality management. Here are some helpful tips for understanding the differences between the two.

Quality Assurance

Quality assurance (QA) is process oriented and focuses on prevention. QA is part of quality management that focuses on requirements being fulfilled. Quality assurance provides confidence both internally to management, as well as externally to customers, government, and regulatory agencies, like the Federal Drug Administration (FDA).

Quality assurance focuses on preventing defects within the processes used to make a product and works to improve the development and testing of product development.

Quality Control

Quality control (QC) is product oriented and focuses on the results of what’s expected. QC is a set of activities to ensure the quality of products, and fulfilling quality requirements. For example, the FDA requires medical device companies to meet their standards, and quality control and a regulated environment is essential. Microbial or environmental testing are good tools to ensure quality. Quality control aims to identify and correct any defects in the finished product prior to being released.

Quality Management Systems

Because quality assurance and quality control are interrelated, an active quality control management system cannot be ignored. A solid quality management system ensures better customer satisfaction, that your team will fully understand the objectives of the quality plan, and how to better identify and fix the root-cause problems.

Quality Standards & Microbial Testing

Quality assurance is a managerial tool that is process oriented, while quality control is a corrective tool that is product oriented. Both of these can be attained through a quality management system and proper testing and procedures.
