Integrated framework for applying complementary safety analysis methods throughout ISO 26262 lifecycle. HARA establishes top-level hazards and ASILs; FMEA identifies component failure modes; FTA quantifies failure combinations; STPA captures emergent hazards. Covers method selection criteria, analysis sequencing, traceability establishment across analyses, consistency checking, and evidence integration. Practical guidance on avoiding redundancy while ensuring comprehensive hazard coverage.
Safety Analyses Overview
How HARA, FMEA, FTA, and STPA complement each other. Select the right method per risk, ensure traceability, and avoid duplicated or inconsistent claims.
