Fault Tree Composer eliminates the tedious, error-prone task of performing safety analysis in a separate, disconnected tool. Stop exporting data to standalone FTA software and manually reconciling results with your requirements — and start doing fault tree analysis where your engineering data already lives, with full traceability, version history, and review workflows built in.
For teams delivering safety-critical products under ISO 26262, IEC 61508, DO-178C, IEC 62304, or EN 50129, Fault Tree Composer turns fault tree analysis from a specialized side task into a first-class Polarion workflow. Every gate, event, and probability calculation is linked to the work items that drive your product — so when requirements change, the impact on your safety analysis is immediately visible.
Powerful Features that Deliver Real Value
- Standards-Compliant Analysis — AND/OR gate logic, event classification, probability calculations, and structured analysis methodology that meet industry safety standards.
- Native Polarion Integration — Every gate and event is a Polarion Work Item. Reuse existing requirements, safety goals, and test cases directly in your fault trees.
- Interactive Visualization — Build and navigate complex fault tree structures as clean, readable diagrams. Automatic layout keeps even large trees organized.
- Full Traceability — Every fault tree event links back to the requirements, safety goals, and test cases it originates from. Trace from failure modes to requirements in one click.
- Probability Calculations — Automatic probability assessment across the entire fault tree structure — no separate calculators, no spreadsheets.
- Team-Wide Viewer Access — Every Polarion user can view fault trees at no extra cost. Editor licenses are only needed for the engineers who build and modify the analysis.
- Audit-Ready Documentation — Fault trees live in Polarion with full version history, review workflows, and traceability. When auditors ask for evidence, it's already there.
