Requirements
Customer, system, and design requirement types that form the foundation of your traceability matrix.
Design Elements
Functions and characteristics that decompose system behavior and support design verification.
Safety Analysis
Failure modes, failure conditions, and risk controls used in FMEA, FHA, and certification assessments.
Verification
Test cases that verify requirements and design against system specifications.
Architecture
System elements that define the hierarchical decomposition of your product.
V-Model Coverage
Work item types follow the V-Model development lifecycle, linking requirements through design to verification:
Entity Relationships
All work item types interconnect through a unified data model:| From | Link Role | To | Purpose |
|---|---|---|---|
| Customer Requirement | implements | System Requirement | Requirements decomposition |
| System Requirement | implements | Design Requirement | Design specification |
| Design Requirement | traces | Function | Functional allocation |
| Function | traces | Characteristic | Design detailing |
| Characteristic | verifiedBy | Test Case | Verification mapping |
| System Requirement | addresses | Failure Condition | Safety requirements traceability |
| Failure Mode | contributesTo | Failure Condition | FMEA-to-FHA linkage |
| Failure Condition | mitigatedBy | Risk Control | Risk mitigation mapping |
Quick Reference
Requirements Hierarchy:- Customer Requirement — User-facing needs from stakeholders
- System Requirement — System-level specification to satisfy customer needs
- Design Requirement — Design-level specification for components and subsystems
- Function — Functional decomposition supporting system behavior
- Characteristic — Design properties enabling verification
- Failure Mode — Component-level failure mechanism used in DFMEA/SFMEA
- Failure Condition — System-level failure state from FHA analysis
- Risk Control — Mitigation action with DAL assignment
- Test Case — Verification test for requirements and characteristics
- System Element — Hierarchical system decomposition (system → subsystem → component)
