Definition:
Test the Initial Level of Interest (ILI) in a yet-to-be-developed product or service by creating artefacts that suggest that the product exists and it’s available to see if people would buy it.
Example:
We know everyone loves fluffy toys, but would they buy a doll? The best way to find out is by using a Fake Door! Set up a basic landing page advertising the dolls (before they exist), asking people to buy. If anyone clicks the button and shows that they’re willing to take the action you’re looking for, let them know they’ve been placed on the waitlist for more stock coming soon.
