Purposedifferent | With only a few minutes available and a still-fuzzy solution search, the method forces a wide range of variants. It produces fast sketches before the first idea can settle in, making different directions directly comparable and open to further development. | When a problem keeps recurring and the cause stays unclear, the method exposes the underlying mechanism. It separates symptom, guess, and robust explanation from one another. | 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. | For a series of incidents with a similar pattern, the method arranges individual events as branches of a common origin. It makes visible which conditions keep recurring. |
