How to do it, step by step
- 1
Describe one user and one job the app must finish end to end.
- 2
Get that path working before adding a second feature.
- 3
Add real data early — demo data hides most design problems.
What usually goes wrong
A prototype with real user data needs real access rules before you share the link.
