Actions should:
eliminate failure mode
eliminate causes
Reduce occurences
Improve evaluation detection
RPN = SxOxD
Severity (S)
Occurrences (O)
Detection (D)
Re-calculate RPN after taking actions
Re-consider Occurrence (O)
Re-consider Detection (D)
Unless failure mode is eliminated severity will stay the same
