|---|---|---|---|
Purposedifferent | The Learning Card connects traceable test results to a reasoned next action while keeping the limits of the insight visible. | 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. | 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. |
