Method and rigour
Check command of hazard analysis methods: HARA, STPA, FMEA, fault tree analysis, and how they applied ISO 26262 ASIL decomposition or ISO 21448 SOTIF triggering condition analysis.
Evidence to listen for
- Follows and can justify an established methodology
- Understands contamination, bias, and chain of custody as they apply to the field
- Knows the limits of their techniques and says so
- Documents procedure so results are reproducible and defensible
Five-point scoring guide
Careless method; unaware of contamination, bias, or procedural integrity.
Knows procedures but applies them inconsistently; gaps in documentation.
Sound standard practice; less certain outside familiar techniques.
Rigorous and well documented; understands the limits of each method.
Names the specific method used per hazard, explains ASIL or SOTIF rationale, and cites acceptance criteria they helped define.
