The system that caused this loss probably needs corrective action to stop recurrence. So, why raise an NC when every Corrective Action Request also includes a description of the nonconformity’s:
A. Nature
B. Requirement not fulfilled
C. Evidence requirement was not fulfilled.
It may also include a description of the consequences of the NC to share the benefits of risk-based thinking as in no consequence = why keep the record, for example.
BTW, the PA part of your CAPA may cause folk to think preventive action is stopping recurrence when it is action to prevent occurrence. Proper PA usually follows the analysis of data to see trends or planning with due regard for risk.
