Purposedifferent
For a critical top event with several possible triggers, the method logically models failure paths. It makes visible which combinations of conditions can lead to damage.For a safety-relevant event or a system with high protection requirements, the method examines where controls failed. It exposes both technical and organizational gaps.When demand only needs to be roughly verified, it tests interest with minimal effort. It measures whether people would take a next step at all.
