User Research

A4: Power Users (Control-First)

• Custom workflows, batch operations, automation
• Want: advanced features, customization, efficiency

Evaluation Frameworks

Cognitive Load Budget (max 8 per screen)

Convenience Score

• Time to complete: < 5 seconds
• Learning curve: zero for basic use
• Error recovery: 1-action undo
• Discoverability: obvious without tutorial
• Predictability: consistent patterns

Timeless UI Tests

1. Strip test (hierarchy works without color?)
2. Trend test (still looks good in 3 years?)
3. Platform test (respects native conventions?)
4. Simplicity test (can't remove more?)
5. Sophistication test (details feel deliberate?)

Principles

1. 5-Second Rule — Common actions < 5 seconds
2. Progressive Disclosure — Simple by default
3. Recognition > Recall — Suggest, don't make them remember
4. Forgiving — Undo everywhere, edit anything
5. Emotionally Aware — Calm, encouraging, celebrate milestones
