RTM Model
Requirements Traceability Matrix model with multi-level hierarchy from user needs through design requirements.
Risk Management Model
Risk analysis model with hazards, risk controls, and custom field storage for severity and probability.
Aerospace Safety Model
4-level requirements hierarchy for DO-178C / ARP 4754A certification with SC/CC classification, test case branches, and compliance formatters.
Medical Device RTM
Component-scoped V-model traceability for ISO 14971 / IEC 62304 with validation and verification branches at each level.
Model Comparison
| Model | Entity Types | Relationships | Key Feature |
|---|---|---|---|
| RTM Model | 5+ (UserNeed, SystemRequirement, DesignRequirement, etc.) | Multi-level hierarchy | Constraints, expansion paths |
| Risk Management Model | Hazard, RiskControl, etc. | Cross-domain linking | Custom fields, enum properties |
| Aerospace Safety | 7 (CustomerReq through FailureMode) | 4-level hierarchy with V&V | SC/CC formatters, 5-state compliance |
| Medical Device RTM | 3 (UserNeed, SystemReq, DesignReq) | V-model with V&V branches | Component scoping, YAML anchors |
