yogsoth-ai Risk Prioritization Strategy
Classifies failure modes into High/Medium/Low action priority using severity-weighted S/O/D scoring.
Method
- Collect S/O/D scores from upstream FMEA analysis
- action-priority-matrix applies AIAG-VDA Action Priority logic:
- H (High): Mandatory action required — severity >= 8, or combined S*O >= 36
- M (Medium): Action recommended — moderate risk combinations
- L (Low): Optional action — acceptable risk level
- Rank all failure modes by priority class, then by RPN within class
- Feed H-priority items to mitigation-design strategy
Budget Table
| Parameter | S | M | L |
|---|---|---|---|
| Failure modes classified | 8 | 20 | 40 |
| Priority threshold tuning | fixed | 1 round | 2 rounds |
| Sensitivity analysis | none | top-5 | full |
Orchestration
[S/O/D scores from upstream] → action-priority-matrix
→ priority-ranked failure catalog
→ [H-priority items] → mitigation-design
Subagents
- action-priority-matrix (RPN computation and H/M/L classification)
- severity-scoring (re-evaluation if needed)
Available Tactics
Optional, no fixed order; the final leaf is always a sop.
| Tactic | When to use |
|---|---|
| premortem-to-fmea-pipeline | Tactic: Pre-mortem rapid screening feeds high-risk items into full FMEA analysis. Bridges fast intuitive generation with systematic structured analysis. |
Available SOPs
Optional, no fixed order; the final leaf is always a sop.
| SOP | When to use |
|---|---|
| action-priority-matrix | Compute Risk Priority Number (RPN = S x O x D), classify failure modes into H/M/L action priority per AIAG-VDA tables. |
| severity-scoring | Rate failure mode severity 1-10 based on end-effect impact. Follows AIAG-VDA severity scale calibrated for research artifacts. |
