# Quality assurance

Quality assurance (QA) is the planned and systematic set of activities that provides confidence a product or service will meet quality requirements. Unlike quality control, which tests outputs, QA focuses on processes, documentation, training and audits that prevent problems, ensuring consistency across batches.
