Quality assurance
The term quality assurance (QA) includes the following meanings:
- All actions taken to ensure that standards and procedures are adhered to and that delivered products or services meet performance requirements.
- The planned systematic activities necessary to ensure that a component, module, or system conforms to established technical requirements.
- The policy, procedures, and systematic actions established in an enterprise for the purpose of providing and maintaining a specified degree of confidence in data integrity and accuracy throughout the lifecycle of the data, which includes input, update, manipulation, and output.
One of the most widely used paradigms for QA management is the PDCA (Plan-Do-Check-Act) approach, also known as the Shewhart Cycle.
Quality assurance is mostly about ensuring compliance with process. Quality assurance is a bit of a misnomer because it is not specifically about quality. In many cases, quality assurance is used to refer to software testing.
