Purposedifferent | For a process problem with fluctuating performance, the method brings analysis and improvement into a disciplined sequence. It creates a framework in which numbers, causes, and control come together. | 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. | When a search for ideas stalls, switching roles helps people step outside their own perspective and activate new logics of action. The method reduces habit because contributions arise from a different stance. This brings unfamiliar, often fitting solution approaches into play. |
