Quality is an important part of any business whether you produce food, automobiles, or technical solutions. Quality Assurance and Quality Control are both important parts of managing quality, but it’s important to point out that they are not the same thing. Quality Assurance is process oriented and focuses on preventing defects, while Quality Control is product oriented and focuses on identifying defects. In this post, we’ll discuss how the two are differ.

What is Quality Assurance? Bug Prevention!

As mentioned above, Quality Assurance involves process oriented activities. Quality Assurance is the process used to develop products and focuses on the prevention of defects. The goal of Quality Assurance is to improve development and testing processes to prevent defects from arising during the product development lifecycle. Using process checklists, performing project audits and employing best practices are examples of Quality Assurance.,/p>

What is Quality Control? Bug Detection!

Quality Control involves product-oriented activities. Quality Control focuses on the identification of defects in products. The goal of Quality Control is to identify any defects after a product is developed, but before it's released to production. Performing peer reviews and the testing process are examples of Quality Control.

When used in conjunction, Quality Assurance and Quality Control can help to consistently develop a quality product. On the Quality Assurance side, developing and adhering to processes can help prevent defects. On the Quality Control side, product testing can help identify defects. Together they pinpoint defects in current processes and the product itself, which provides feedback on what may be the causes of quality problems. By having a consistent process across projects, the feedback loop helps identify the root-causes of defects, and develop strategies to eliminate these problems.
