Traceability Sheets

RTM (Requirements Traceability Matrix) configurations for bidirectional linking across system, design, and component hierarchies.

Data Collection Sheets

Characteristic, process step, and use step configurations for capturing design and process data.

Verification Sheets

Test traceability and verification evidence sheets aligned to system, design, and subsystem levels.

Function and Hierarchy Sheets

System decomposition and functional allocation sheets for system structure management.

​
Key Features

  • 11 PowerSheet configurations supporting traceability, characteristics, functions, verification, and use case management
  • Hierarchical data models with multi-level expansion paths (system → subsystem → component; requirement → test)
  • Dynamic column grouping with conditional visibility and custom renderers for SC/CC classification, ASIL levels, and risk indicators
  • Progressive disclosure views showing aggregated summaries, detailed analysis, and traceability chains
  • Bi-directional traceability linking requirements across V-model stages: validation ← system ← design ← verification
  • Work item expansion enabling in-place navigation through document hierarchies without page navigation
  • Custom formatters for color-coded badges, formula-based calculations, and linked evidence rendering
  • Integration with risksheet analysis cross-referencing FMEA, Control Plans, and risk controls

PowerSheet navigation is optimized for discovery and cross-linking. Use expansion arrows to drill into child work items without leaving the sheet. Use filtering to scope to specific components or subsystems. Combine multiple PowerSheets (e.g., Component RTM + Characteristics) to validate bidirectional traceability and requirements → design → test coverage chains.
PowerSheet configurations reference custom fields, enumerations, and link roles defined in the RTM domain model. Changes to work item types or fields require consistency checking via the consistency-check skill before deploying to production.

Common Workflows

Requirements Traceability: Start with Whole RTM to map customer needs → system requirements → design requirements → verification tests. Then drill into Component RTM to validate component-level coverage. Design Verification Planning: Use System Verification to allocate tests to system requirements, then Design Verification for design-level test mapping, and Subsystem Verification for subsystem-specific test plans. Characteristics Management: Define design parameters in Characteristics, classify SC/CC items, and link to failure modes in parallel FMEA risksheets. Use Component Characteristics for supplier-specific tolerances. Safety Analysis Integration: FMEA failure modes reference characteristics through link cells in Characteristics. Process failure modes reference process steps in Process Steps, enabling traceability from design through manufacturing controls. System Architecture: Use Subsystem Functions to allocate functions to system elements, then validate bidirectional links to design requirements and characteristics.
