What are the CAQ Significance levels?
- Level 1Q (SCAQ):*
- *Condition with major impact warranting investigation.**
Events or occurrences are expected to happen rarely and consequences are serious.
- Level 2Q (CAQ-S):*
- *Condition with moderate impact warranting investigation.**
Events or occurrences are less serious in nature.
- Level 3Q (CAQ-D):*
- *Low level Condition**
Condition may be non-consequential but actions are required to address issue/behavior.
- Level 4Q (CNAQ):*
- *Condition with no or minimal impact.**
Such as low level material deficiencies on NRS components enhancements, non-consequential issues, tracking issues (e.g. condition not adverse to Quality)
