Purposedifferent | For an acute quality or delivery problem, the method structures immediate protection and root cause work together. It keeps the situation stable while the actual cause is investigated cleanly. | For persistent errors or blockages, the method shifts the view to the opposite of the desired effect. It exposes the mechanics of failure and makes hidden causes easier to grasp. This makes improvement more concrete and the problem clearer. | 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 central question feels too large, the method breaks it into neighboring topic fields with their own depth of ideation. It holds structure and openness at the same time, so adjacent perspectives don't get lost. This grows an idea space out of a core problem. |
