|
A characteristic, factor, or aspect of a product, process, service, or system
that renders it nonconforming – e.g., inaccurate, inoperable, or of less than
acceptable quality. Defects can be categorized into four "classes": 1) "very
serious," i.e., causing "severe" physical and/or economic harm; 2) "serious,"
i.e., causing "significant" physical or economic harm; 3) "major," i.e.,
causing substantial problems or difficulties with the unit's intended use; and
4) "minor," i.e., causing relatively inconsequential problems or difficulties
with the unit's intended use. |
