quality assurance
planned and systematic action necessary to provide adequate confidence that a product or service will satisfy given requirements for quality. Quality is built into the product or service, rather than 'inspected in'.
quality control
the use of operational techniques, particularly end-product testing or inspection to ensure that a product or service satisfies its stated or implied role.
