Quality means meeting requirements and meeting customer needs, which means a defect-free product from both the producer’s and the customer’s viewpoint. Quality is an attribute of a product or a service. Quality is achieved through processes. Both Quality Control (QC) and Quality Assurance (QA) are used to make quality happen.

Quality Assurance is the focus on the process which delivers and ensures quality and Quality Control uses methods to compare product quality to requirements and applicable standards, and the action taken when a nonconformance is detected. Once the processes are consistent, they can "assure" that the same level of quality will be incorporated into each product produced by that process
