- Prevention - now investment
- Appraisal- now monitoring
- Internal failure- now waste
- External failure - now downstream consequences
One member sent a comment to QP staff regarding the definition of “cost of quality” that’s included in the glossary
The current entry reads as follows:
"Cost of quality (COQ): Another term for COPQ. It is considered by some to be synonymous with COPQ but is considered by others to be unique. While the two concepts emphasize the same ideas, some disagree as to which concept came first and which categories are included in each".
This member suggested that in order to avoid confusion that Appraisal and Prevention are not due to Poor Quality, all four cost categories are typically grouped under COQ. The internal and external failure costs are grouped specifically under COPQ. i.e COPQ is a subset of COQ. We could also separate Appraisal and Prevention costs to COGQ Cost of Good Quality.
