|---|---|---|---|
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. | When a user journey falls apart across many touchpoints, customer journey mapping makes the experience visible as a coherent arc. Phases, emotions, and breaks become legible enough to prioritize critical moments deliberately. | When a journey needs to be understood across several phases, it arranges experience, touchpoints, and opportunities into one picture. It makes gaps and friction along the user path clear. |
