STPA applies system-theoretic accident modeling to identify unsafe control actions arising from complex interactions, timing issues, and emergent behaviors beyond traditional failure modes. Particularly valuable for autonomous systems, software-intensive architectures, and adaptive algorithms. Identifies hazardous scenarios through control structure analysis, unsafe control action identification, and loss scenario derivation. Integrates with ISO 26262 HARA and FMEA for comprehensive hazard coverage.
