Purposedifferent | When three perspectives matter at the same time, a Three-Circle Venn Diagram shows the overlaps and remainders precisely. It makes visible where shared effect arises and where only a partial perspective applies. | 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. |
