What is STPA?
STPA (System-Theoretic Process Analysis) is a powerful hazard analysis technique based on systems theory. It identifies potential hazards by modeling the system as a control loop and examining potential control flaws that could lead to accidents. It is commonly used in safety-critical systems to identify unsafe control actions and design safety constraints.
What other technologies are related to STPA?
STPA Competitor Technologies
FTA
FTA (Fault Tree Analysis) is a top-down, failure-based hazard analysis technique, and can be viewed as a competitor to STPA, which is a system-theoretic approach that analyzes hazards from a control and system interaction perspective.
FMEA
FMEA (Failure Mode and Effects Analysis) is a bottom-up, failure-based hazard analysis technique. It competes with STPA, which considers a broader scope of system-level causes, including unsafe control actions and system interactions.
STPA Complementary Technologies
ISO 21448
ISO 21448 (SOTIF) focuses on the safety of intended functionality, which is complementary to STPA's broader system-theoretic hazard analysis. STPA can help identify scenarios that SOTIF might miss, particularly those arising from complex interactions.
ISO 26262
ISO 26262 is a functional safety standard for automotive systems. STPA can be used to provide system-level hazard analysis as input to the ISO 26262 development process, making them complementary.
