Overview of Quality Assurance (QA)

Quality Assurance (QA) is a process that is used to control and improve the development of a product or service to ensure it will meet all specifications and requirements. QA involves improving the product development and manufacturing process, rather than looking at the end products themselves. 

Although they are sometimes confused, QA is different than Quality Control (QC). QC focuses more on detecting problems in the finished products, rather than looking at the development process. 

The overarching goal behind QA is to prevent flaws or defects before they occur. QA involves improving processes such as design, worker training, document control, management, and process audits. This is because flaws in these processes can lead to flaws in the products or services offered to customers further down the line.
