Hazard Identification · Risk Rating · ASIL Assignment
Overview
HARA (Hazard Analysis and Risk Assessment) systematically identifies hazardous events resulting from system malfunctions, assesses their severity and controllability, and assigns ASIL ratings — providing the safety goals that drive all downstream safety requirements. Our HARA process follows the ISO 26262 Part 3 methodology, using structured workshops and analysis tools to enumerate hazardous situations, assess S/E/C parameters, and derive ASIL-rated safety goals with full traceability to the item definition.

Key Aspects
Combining system functions with operational situations and failure modes to enumerate all credible hazardous situations that could arise from malfunctioning behaviour.
Assessing each hazardous situation against the severity of injury (S0–S3) and the ability of a driver or third party to control the situation (C0–C3).
Estimating the frequency and duration of exposure to each operational situation (E0–E4) — a key parameter in the ASIL classification.
Combining S, E, and C ratings to determine the ASIL (QM, A, B, C, D) for each hazardous event and formulating the corresponding safety goals.
