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.
Todos Model
Lightweight task management model with todo items, tasks, and requirements traceability.
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 |
| Todos Model | TodoItem, Task, Requirement | Simple hierarchy | Minimal configuration |
| 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 |
