Defect — A defect is any outcome that fails to meet a defined requirement.

Last updated: 2026-02-05

In plain English

A defect is anything that doesn’t meet expectations.

Customer expectations.
Regulatory expectations.
Process expectations.

What they actually mean

Defects are often defined narrowly to make numbers look better.

If customers complain but defects stay “low”, the definition is wrong.

Example

“Each incorrect shipment was counted as a defect.”

Does it actually matter?

✅ Yes — definition matters more than counting.
