Overview
The Home Dashboard serves as a project control center for safety engineering teams. It displays:
- Live project statistics — counts of requirements, test cases, failure modes, risk controls, and other work items
- Document inventory — hierarchical view of all LiveDoc modules organized by system element structure
- Space dashboards — quick links to Requirements, Design, Risks, and Testing space dashboards
- Role dashboards — links to Safety Engineer, Design Engineer, V&V Engineer, Configuration Manager, and Program Manager views
- Standards compliance reports — navigation to ISO 26262 HARA, HAZID, FMEA, and control plan reports
- Traceability metrics — coverage bars showing V-model verification chain completeness
Dashboard Statistics Bar
The Home Dashboard displays a real-time statistics bar showing key artifact counts:
| Metric | Value | Significance |
|---|
| Customer Requirements | Count | Baselined customer-facing needs |
| System Requirements | Count | Allocated system-level specifications |
| Design Requirements | Count | Decomposed design-level specifications |
| Functions | Count | System element functional mappings |
| Characteristics | Count | Design attributes under control (IATF 16949) |
| Failure Modes | Count | Total across SFMEA, DFMEA, PFMEA |
| Risk Controls | Count | Mitigation measures for identified hazards |
| Test Cases | Count | Verification and validation evidence |
| Hazards | Count | ISO 26262 HARA analysis results |
| Safety Goals | Count | Derived from hazard analysis |
| System Elements | Count | Architectural decomposition levels |
Dashboard metrics refresh when the page loads. Use the browser refresh button to see real-time counts after work item modifications. Lucene query engine in Polarion indexes changes within 5–10 seconds.
Document Inventory Tree
The document inventory tree provides hierarchical navigation to all LiveDoc modules in the project:
AEB System
Sensor Housing Subsystem
- Sensor Housing Assembly — Component DFMEA, Design Characteristics
- Camera Module — Component DFMEA, Design Characteristics
- Radar Module — Component DFMEA, Design Characteristics
ECU Processing Subsystem
- System-on-Chip (SoC) — Component DFMEA, Design Characteristics
- [5 more components…]
Vehicle Interface Subsystem
- CAN Transceivers — Component DFMEA, Design Characteristics
Each document entry shows:
- System Element — hierarchical path (system / subsystem / component)
- Document ID — Polarion module identifier
- Status — Approved, In Review, Draft, or Obsolete
- Work Items — count of requirements, failure modes, or test cases in module
- Tool — Risksheet (for analysis tables) or PowerSheet (for traceability matrices)
Clicking any document opens it in the Risksheet or PowerSheet editor.
Documents are organized by system element hierarchy in the RTM domain model. Each system element can own multiple analysis documents (SFMEA, DFMEA, characteristics sheet). The tree structure reflects the V-model decomposition from system → subsystem → component level.
Space Dashboards
Space dashboards provide domain-specific views for each engineering discipline:
| Space Dashboard | Purpose | Key Metrics |
|---|
| Requirements Space Dashboard | System and subsystem requirements, traceability to system requirements | Customer Reqs, System Reqs, Traceability Coverage % |
| Design Space Dashboard | Design requirements, functions, characteristics, design verification | Design Reqs, Functions, Characteristics, Test Cases |
| Risks Space Dashboard | HARA analysis, FMEA, risk controls, mitigation effectiveness | Hazards, Failure Modes, Risk Controls, ASIL Distribution |
| Testing Space Dashboard | Test cases, validation/verification evidence, coverage reports | Test Cases, Verification Coverage %, Validation Status |
| Documentation Space Dashboard | Project documentation modules, lifecycle workflow, approval status | Total Modules, In Review, Pending Approval, Approved |
Role Dashboards
Role dashboards are customized views designed for specific project roles:
| Role Dashboard | Target Audience | Key Information |
|---|
| Safety Engineer Dashboard | Functional safety, ASIL, hazard analysis, risk controls | HARA completeness, ASIL matrix, hazards by severity, risk control effectiveness |
| Design Engineer Dashboard | System and design requirements, functions, characteristics | Design req coverage, function allocation, characteristic traceability to failure modes |
| V&V Engineer Dashboard | Verification and validation, test coverage, requirements traceability | Test case counts by type, verification coverage %, validation status |
| Configuration Manager Dashboard | Baselines, document workflow, change control | Document approval status, pending reviews, workflow transitions |
| Program Manager Dashboard | Project health, milestone status, standards compliance | Overall readiness %, traceability coverage, FMEA closure rate, risk status |
Standards Compliance Reports
The Home Dashboard provides quick links to compliance and analysis reports:
ISO 26262 Functional Safety
| Report | Content |
|---|
| ISO 26262 HARA Report | Hazard Analysis and Risk Assessment per Part 3, showing hazards, ASIL classification, and derived safety goals |
| HAZID Risk Matrix Report | Visual risk matrix (Severity × Probability) for all identified hazards |
FMEA Analysis
| Report | Content |
|---|
| FMEA Reports | Summary of System FMEA, Design FMEA, and Process FMEA across all components |
| FMEA Coverage Report | Identification of safety-classified requirements/functions not yet covered by FMEA |
| System DFMEA Report | Detailed design FMEA for system-level components |
| System PFMEA Report | Process FMEA for manufacturing and assembly control |
Traceability & V-Model
| Report | Content |
|---|
| Requirements Traceability Report | Bidirectional traceability matrix: Customer → System → Design → Test, with gap analysis |
| System Structure Navigator | Interactive visualization of system decomposition hierarchy and element relationships |
| Data Model Diagram | Entity-relationship diagram showing work item types and link roles |
Manufacturing & Control
| Report | Content |
|---|
| Risk Control Effectiveness Report | Pre-mitigation vs. post-mitigation risk assessment, showing control effectiveness |
| Control Plans Report | Manufacturing control plan for process steps, characteristics, and inspection methods (IATF 16949) |
Traceability Coverage Metrics
The Home Dashboard displays traceability coverage bars for each V-model phase:
Each coverage bar shows:
- Numerator — linked items meeting traceability criterion
- Denominator — total items requiring linkage
- Percentage — coverage metric (0–100%)
- Gap description — specific count and nature of missing links
Red gaps indicate untraced requirements that may violate ISO 26262 Part 8 (Clause 6) bidirectional traceability requirements. Click the gap count to view the list of unlinked items and establish missing links before document approval.
Dashboard Navigation Workflow
Typical workflows for using the Home Dashboard:

Dashboard Customization
Home Dashboard widgets can be customized through Polarion page editing:
| Customization | Method |
|---|
| Change statistics bar metrics | Edit Velocity script in page.xml; modify work item type or Lucene query |
| Reorder space dashboard links | Drag-and-drop widget order; changes persist in Polarion page layout |
| Add custom report sections | Create new Velocity wiki page; link from Home Dashboard via Reports section |
| Modify document inventory hierarchy | Edit RTM domain model in .polarion/nextedy/models/; rebuild document tree |
| Adjust coverage thresholds | Edit nxLinkCoverage macro parameters; typical threshold 80% for green, 50% for yellow, <50% red |
