Quality control
Quality control uses operational methods and checks to meet quality requirements and identify non-conformance. Inspection, testing, process monitoring and corrective action can contribute, depending on the process. It is related to quality assurance but has a more operational focus on conformance. The system should learn from failures and avoid shifting problems to customers rather than simply reject or rework outputs repeatedly.
Worked example
A measured component is checked against tolerance, non-conforming output is isolated and the process cause investigated before further batches are released.
Common mistake
Checking quality does not remove the need to prevent defects, and a sample check does not prove every output conforms.
