stpa-overview

STPA hazard analysis is a system theoretic process for identifying unsafe control actions in complex systems. It guides users through defining losses, modeling control structures, and developing loss scenarios to pinpoint failure points in control systems.

To perform STPA, you sequentially execute four steps: defining system losses, modeling the control-feedback structure, identifying unsafe control actions, and developing loss scenarios to systematically document hazard analysis.

You need STPA for risk assessment when analyzing complex systems where traditional hazard analysis falls short, specifically to model control-feedback loops and identify unsafe control actions in safety-critical architectures like autonomous vehicles.

Yes, you can use this STPA guide to model control structure diagrams for safety engineering. It facilitates the creation of control-feedback structures and requires interactive input to document the hazard analysis process.

STPA for system safety analysis requires interactive user input and continuous documentation updates in PROJECT_MANAGEMENT.md and GOAL.md. It is an intermediate-level process focused on control systems, which may require significant manual modeling effort for complex architectures.

No, this STPA hazard analysis requires no external dependencies or tools. It operates as a standalone guide using standard markdown documentation files like PROJECT_MANAGEMENT.md and GOAL.md to track the hazard identification process.
