Glossary · Functional Safety
Functional Safety: Engineering discipline that protects against unreasonable risk caused by malfunctioning behaviour. Functional safety (ISO 26262 in automotive, IEC 61508 generically) systematically reduces the risk of harm from system malfunctions.
Where this matters: Functional Safety Engineering (ISO 26262)
It produces hazard analyses (HARA), safety goals, safety concepts, FMEDA-backed hardware metrics, software architecture and unit-level evidence, and the safety case that anchors final assessment.
