Progress
Lighter toward the end
Effort: Medium
What to notice
Each step asks for less, until the last one is a single confirm button.
How to build it
- Group required fields early and leave only review and choices for later.
- Make the final step a single action.
- Just before completion, say what pressing the button will do.
Measure
- Main metric
- Completion rate at the final step
- Guardrail
- Drop-off at the first step
When it backfires
Overloading the start drives people away early. Put heavy input after the value is clear.
