Systems Hazards Analysis is a method that includes both human and hardware factors. It systematically tracks through a system to identify hazards that could lead to failures. There are specific definitions for processes, operations, and tasks. One type of analysis identifies information about the process, operations, tasks, potential variances from safe practices, hazards, triggering events, incidents, effects, and consequences. Both inductive and deductive methods are used. Deductive methods like Fault Tree Analysis work backwards from an end event to identify possible causes using Boolean logic and algebra to represent interactions between events.
