Quality assurance (QA) is the act or process of certifying that a company’s quality criteria are met. Planning, completing, and monitoring tasks are all part of managing quality in production. The monitoring aspect is the essence of what quality assurance is.

The techniques and procedures that systematically monitor multiple aspects of a service or facility make up the quality assurance process. Quality assurance activities uncover and fix faults or deviations from defined standards or requirements through audits and other forms of assessment.
