Occurrence rating process SWFMEA.
| Occurrence rating | Probability of failure | Rating | Criteria |
| Very frequently | 10 | Shows greater than 80% of defects attributable to subprocess failure | Frequently | 8 | Shows greater than 40% of defects & less than 80% of defects attributable to subprocess failure | Sometimes | 4 | Shows greater than 10% of defects & less than 40% of defects attributable to subprocess failure | Rare | 1 | Shows less than 10% of defects to subprocess failure. |
| Severity rating | Effect | Rating | Criteria |
| Very high | 10 | Rework is greater than 8 ph | High | 7 | Rework is greater than 4 ph & <8 ph | Moderate | 5 | Rework is greater than 2 ph & <4 ph | Low | 3 | Rework is greater than 1 ph & <2 ph | Very low | 1 | Rework is greater than 1 ph |
| Detectability rating | Detection | Rating | Criteria |
| Difficult | 10 | No defined methods for identifying the process error; only the o/p prdt analysis leads to detectability | Moderate | 5 | Can be identified in the exit phase of the process or subsequent process entry check | Easy | 1 | Process has built in checks for identifying subprocess failure |
