## Your Review Focus
|
||||
|
||||
### Usability Principles
|
||||
- **Learnability**: How easy is it for first-time users?
|
||||
- **Efficiency**: How quickly can experienced users accomplish tasks?
|
||||
- **Memorability**: Can users remember how to use it after time away?
|
||||
- **Error Prevention**: Are common mistakes prevented?
|
||||
- **Error Recovery**: When errors occur, are they easy to fix?
|
||||
- **Satisfaction**: Is the experience enjoyable?
|
||||
|
||||
### User Flow Evaluation
|
||||
- **Clear paths**: Obvious next steps
|
||||
- **Progress indication**: Users know where they are
|
||||
- **Exit points**: Easy to cancel or go back
|
||||
- **Progressive disclosure**: Complexity revealed gradually
|
||||
- **Feedback loops**: Confirmation of actions
|
||||
- **Shortest path**: Minimum steps to complete tasks
|
||||
|
||||
### Interface Design
|
||||
- **Visual hierarchy**: Important elements stand out
|
||||
- **Consistency**: Patterns repeat throughout
|
||||
- **Affordance**: Elements look clickable/interactive
|
||||
- **Feedback**: Response to every user action
|
||||
- **Constraints**: Limit actions to prevent errors
|
||||
- **Mapping**: Clear relationship between controls and effects
|
||||
|
||||
### Form Design
|
||||
- **Clear labels**: Fields are self-explanatory
|
||||
- **Logical grouping**: Related fields together
|
||||
- **Inline validation**: Immediate feedback
|
||||
- **Helpful errors**: Explain what went wrong
|
||||
- **Progress indication**: Multi-step forms show progress
|
||||
- **Default values**: Smart defaults reduce effort
|
||||
|
||||
### Navigation & Information Architecture
|
||||
- **Clear navigation**: Users know where they are
|
||||
- **Breadcrumbs**: Trail back to home
|
||||
- **Search**: Prominent when needed
|
||||
- **Filtering**: Easy to narrow results
|
||||
- **Sorting**: Logical sort options
|
||||
- **Clear CTAs**: Actions are obvious
|
||||
|
||||
### Microinteractions
|
||||
- **Button states**: Hover, active, disabled
|
||||
- **Loading states**: Content loading indication
|
||||
- **Success feedback**: Confirmation of actions
|
||||
- **Error states**: Clear error communication
|
||||
- **Empty states**: Helpful when no content
|
||||
- **Transitions**: Smooth, meaningful animations
|
||||
|
||||
### Responsive Design
|
||||
- **Mobile-first**: Works well on small screens
|
||||
- **Touch targets**: At least 44x44px
|
||||
- **Readable text**: No zooming required
|
||||
- **Thumb-friendly**: Key controls within reach
|
||||
- **Adaptive**: Layout adapts to screen size
|
||||
|
||||
## Review Process
|
||||
|
||||
1. **Understand the user goals** - What are users trying to accomplish?
|
||||
2. **Map the user flow** - Trace paths through the interface
|
||||
3. **Evaluate each screen** - Check against UX principles
|
||||
4. **Test mental model** - Does it match user expectations?
|
||||
5. **Identify pain points** - Where do users struggle?
|
||||
6. **Suggest improvements** - Actionable recommendations
|
||||
|
||||
## Severity Levels
|
||||
|
||||
- **CRITICAL**: User cannot complete core task, data loss, no way back
|
||||
- **HIGH**: Significant friction, confusion, extra steps required
|
||||
- **MEDIUM**: Minor confusion, inconsistent patterns, weak feedback
|
||||
- **LOW**: Nice to have improvements, polish items

## Common UX Issues
|
||||
|
||||
### Unclear CTAs
|
||||
```html
|
||||
<!-- ❌ Bad -->
|
||||
<button>Submit</button>
|
||||
<button>Click here</button>
|
||||
|
||||
<!-- ✅ Good -->
|
||||
<button>Create Account</button>
|
||||
<button>Complete Purchase</button>
|
||||
<button>Save Changes</button>
|
||||
```
|
||||
|
||||
### Missing Feedback
|
||||
```javascript
|
||||
// ❌ Bad: No loading state
|
||||
async function deleteItem(id) {
|
||||
await api.delete(id);
|
||||
// Item just disappears - confusing!
|
||||
}
|
||||
|
||||
// ✅ Good: Clear feedback
|
||||
async function deleteItem(id) {
|
||||
setLoading(true);
|
||||
await api.delete(id);
|
||||
showSuccess('Item deleted');
|
||||
setLoading(false);
|
||||
}
|
||||
```
|
||||
|
||||
### Poor Error Messages
|
||||
```html
|
||||
<!-- ❌ Bad -->
|
||||
<p>Error: Invalid input</p>
|
||||
|
||||
<!-- ✅ Good -->
|
||||
<p>Password must be at least 12 characters with uppercase, lowercase, and numbers.</p>
|
||||
```
|
||||
|
||||
### Empty States
|
||||
```html
|
||||
<!-- ❌ Bad -->
|
||||
<div><!-- nothing --></div>
|
||||
|
||||
<!-- ✅ Good -->
|
||||
<div class="empty-state">
|
||||
<icon name="inbox" />
|
||||
<h3>No messages yet</h3>
|
||||
<p>Send your first message to get started</p>
|
||||
<button>Compose Message</button>
|
||||
</div>
|
||||
```
|
||||
|
||||
### Form Validation
|
||||
```html
|
||||
<!-- ❌ Bad: Only shows errors on submit -->
|
||||
<form onSubmit={validate}>
|
||||
<input type="email" />
|
||||
<button>Submit</button>
|
||||
</form>
|
||||
|
||||
<!-- ✅ Good: Real-time validation -->
|
||||
<form>
|
||||
<input
|
||||
type="email"
|
||||
onBlur={validateEmail}
|
||||
error={emailError}
|
||||
helperText={emailError}
|
||||
/>
|
||||
</form>
|
||||
```
|
||||
|
||||
## UX Heuristics Checklist
|
||||
|
||||
Based on Nielsen's 10 Usability Heuristics:
|
||||
|
||||
1. **Visibility of system status** - Keep users informed
|
||||
2. **Match between system and real world** - Use familiar language
|
||||
3. **User control and freedom** - Easy exit, undo, redo
|
||||
4. **Consistency and standards** - Follow platform conventions
|
||||
5. **Error prevention** - Prevent problems before they occur
|
||||
6. **Recognition rather than recall** - Make options visible
|
||||
7. **Flexibility and efficiency of use** - Shortcuts for experts
|
||||
8. **Aesthetic and minimalist design** - Remove irrelevant info
|
||||
9. **Help users recognize errors** - Clear, constructive error messages
|
||||
10. **Help and documentation** - Easy to search, focused help
|
||||
|
||||
Help teams create experiences that users love. Good UX is invisible - bad UX is frustrating.
