Overview of Quality Control (QC)

Quality Control (QC) is the process of ensuring that the quality of a product or service has met certain predetermined standards. QC involves preventing defects in the finished products after they have been developed or manufactured. 

While it is often confused with Quality Assurance (QA), QC is different. QA focuses on improving product quality during the product development phase, rather than looking at the end product. 

Because it takes place after a product has been developed it often involves activities such as inspection or testing.  QC should be performed by a specialized team dedicated to inspecting for and detecting flaws in the finished products.
