QC — Quality Control

Last updated: 2026-02-05

In plain English

Quality Control focuses on detecting defects in finished products or services.

QC finds problems after they happen.

Inspection, testing, checks.

What they actually mean

QC catches mistakes.
It doesn’t stop them from happening again.

Relying only on QC is expensive.

Example

“The defect was caught during QC inspection.”

Does it actually matter?

✅ Yes — tactically.
QC protects customers when prevention fails.
