Quality Control Definition

Quality control (QC) is the process of verifying that a product adheres to a defined set of quality standards or requirements. The objective is to identify and eliminate any defects or errors after a product is manufactured, but before it is shipped to customers.

Typical QC activities include testing, inspection, and documentation. During the QC process, data related to defects, bugs, or unit failures is collected and communicated to key stakeholders, Corrective actions (e.g., repair, retraining, work instruction revision) are decided upon and then implemented to resolve the quality issue and improve the production process.
