CRITERIAS FOR PROBABILITY OF OCCURANCE (Po)
Defect Occurrence                                   Control Measures                            Rating
Virtually impossible for the defect to occur        Fool proof                                     1
Very low probability that the defect appears        Reliable control measures in place           2-3
Low probability that the defect appears             Limited control measures in place            4-5
Some probability that the defect appears            Low amount of control measures               6-7
High probability that the defect appears            Unreliable control measures                  8-9
Defect always occurs                                No control measures                           10



CRITERIAS FOR SEVERITY (S)
Accident hazard                                     Quality defects                             Rating
No accident hazard                  or              No defects                                     1
No accident hazard                  or              Insignificant defect - no rework required    2-3
Very low accident hazard            or              Defect - possible rework required            4-5
Accident hazard possible            or              Defect - rework required                     6-7
Accident hazard likely              or              Significant defect - Rework unlikely         8-9
Accident eminent                    or              Scrap - rework impossible                     10



CRITERIA FOR PROBABILITY OF DETECTION (Pd)
Defect Detection                                    Percentage of Detection                     Rating
Defect will be always noticed                       100%                                           1
Very high probability for detection                 80% of this defect will be found             2-3
High probability for detection                      60% of this defect will be found             4-5
Some probability for detection                      40% of this defect will be found             6-7
Low probability for detection                       20% of this defect will be found             8-9
It is impossible for this defect to be found        0%                                            10
