Hazard and Risk Assessment (H&RA)
These are the various terms in the ecosystem of doing Hazard and Risk Assessments (H&RA). Such as HAZID, HAZOP, risk graph, and many more. This is a significant part of the functional safety ecosystem, which is why there are so many associated terms.
Reminder that an H&RA is both identifying the hazard and then assessing the hazards. It is two things. Somet tools do one of those things and others do both.
