|---|---|---|---|
Purposedifferent | For a risk that can only be managed through multiple layers of protection, the method examines the effectiveness of each barrier. It shows where safeguards are missing, too weak, or fail under real conditions. | A Current Reality Tree condenses many symptoms into a few causal chains. The method makes visible which core problems drive several negative effects at once. | The Theory of Constraints Thinking Process exposes a system's bottleneck and the logic behind it. It suits situations where many symptoms trace back to the same limiting relationship. |
