Build Prototypes That Look Real by Designing the Data Before the UI

Make prototypes more credible by designing realistic data, states, and edge cases before generating UI.

Outcome

A prototype that supports better feedback because it represents realistic product states.

Workflow steps

1

Define realistic records

Create sample users, accounts, statuses, permissions, and edge cases.

2

Map product states

Include empty, loading, error, success, and partially complete states.

3

Generate UI from data

Use the data model and sample records as the foundation for the prototype.

Why this workflow matters

A prototype with fake-looking data produces shallow feedback. Realistic data makes product questions visible.

How to run it

Before generating screens, define the data model, representative records, edge cases, and states the UI must handle.

What good looks like

Stakeholders should react to product behavior and tradeoffs, not placeholder content.
