TARA Configuration
ISO/SAE 21434 automotive cybersecurity threat analysis with 5-level merge hierarchy, feasibility scoring, and risk verdict matrix.
FMEA Configuration
Failure Mode and Effects Analysis with RPN formulas, Action Priority logic, severity formatting, and cascading cross-document links.
Example Comparison
| TARA | FMEA | |
|---|---|---|
| Methodology | ISO/SAE 21434 threat analysis | AIAG-VDA / ARP 4761 failure analysis |
| Hierarchy levels | 5 (Stakeholder → Threat Path) | 3 (System Element → Cause) |
| Risk metric | Impact × Feasibility verdict (1-5) | RPN = Severity × Occurrence × Detection |
| Alternative metric | — | Action Priority (H/M/L logic) |
| Formulas | 2 (feasibility weighted sum, verdict matrix) | 3 (initial RPN, revised RPN, Action Priority) |
| Workflow views | 7 phased views | 10 step-by-step views |
| Cross-document links | Task links to risk controls | Upstream/downstream FMEA cascade |
