What to notice
Show whose task is helped and a concrete output before listing features.
Where it fits
- Fits
- Business-service visitors unable to judge value from feature lists.
- Use it when
- When a useful task and its limitations can be shown concretely.
- Avoid it when
- When only unverified effects or fabricated customer outcomes are available.
How to build it
- Choose one representative task and verifiable output.
- Pair input and output, labeled as real or illustrative.
- Place unsuitable conditions nearby.
Measure
- Main metric
- Share of eligible visitors correctly describing the use case
- Guardrail
- Inflated expectations and ineligible applications
- How to measure
- Allocate comparison groups before exposure and use equal follow-up and eligibility. Track Share of eligible visitors correctly describing the use case alongside Inflated expectations and ineligible applications.
