The peak-end rule is an observation that a high-intensity moment and the ending can influence memory more than an experience's average. Delivery, setup, and support remain part of a brand experience after purchase.
The demo changes the final point of the same journey and highlights the two moments. Its memory cue is illustrative, not a formula for actual satisfaction.
Polishing the final scene cannot erase repeated friction earlier in a journey. Measure the whole experience before deciding what to improve.
When to use
Use it to inspect high-intensity and closing moments in a customer journey.
