System-Theoretic Process Analysis (STPA)

System-Theoretic Process Analysis (STPA) is a method used to identify and prevent safety hazards in complex systems. It looks beyond individual components to analyze how the entire system interacts and how specific combinations or failures can lead to accidents or unsafe outcomes. By understanding these interactions and potential failure points, engineers can design safeguards and improve system reliability. Essentially, STPA provides a structured way to foresee and mitigate risks in intricate, interconnected systems, ensuring safety and performance in areas like aviation, healthcare, and transportation.
