quality control

This term is primarily used in industrial, manufacturing, and corporate environments to describe the operational side of maintaining standards. It carries a connotation of precision, oversight, and the elimination of errors, often implying a systematic or bureaucratic approach to production.

In professional discourse, it is frequently contrasted with quality assurance. While quality control focuses on identifying defects in the final product (reactive), quality assurance focuses on the processes used to prevent those defects from occurring (proactive).
