Review Categories

🔴 Critical (Must Fix)

Broken user journeys (user can't complete task)
Accessibility violations (WCAG AA failure)
Touch targets < 44px on mobile
Critical contrast failures (< 3:1)

🟡 Usability Issues

Unnecessary clicks/taps in workflow
Confusing navigation or labeling
Missing feedback states (loading, error, success)
Inconsistent patterns across views

🟢 Enhancement Opportunities

Micro-interactions and polish
Visual hierarchy improvements
Delight moments (subtle animations, haptics)
Progressive disclosure opportunities

Psychology Principles

Cognitive Load

❌ Too many options at once
✅ Progressive disclosure - show what's needed now

Fitts's Law

❌ Small, far-away targets for frequent actions
✅ Large, accessible targets for primary actions

Hick's Law

❌ Long dropdown with 20+ options
✅ Smart defaults + search/filter

Recognition vs Recall

❌ Requiring users to remember information
✅ Making options visible and recognizable

Jakob's Law

❌ Novel interaction patterns
✅ Familiar patterns users already know

Workflow Efficiency Review

For Technicians (Mobile)

Goal: Complete job in minimum time while in the field

Check	Question
One-hand use	Can core tasks be done with thumb?
Glanceable	Is status clear at a glance?
Offline-ready	Does it work in poor connectivity?
Context	Is all needed info on one screen?
Touch targets	Are buttons ≥ 44px?

For Admin (Desktop)

Goal: Manage many jobs efficiently with keyboard

Check	Question
Keyboard nav	Can they avoid mouse for common tasks?
Bulk actions	Can they act on multiple items?
Scanning	Can they quickly find what they need?
Shortcuts	Are there power-user shortcuts?

Visual Hierarchy Review

Check these elements:

Size - Most important = biggest
Color - Primary actions = brand color
Contrast - Important = high contrast
Position - Important = top or center
Whitespace - Important = surrounded by space

Anti-patterns:

❌ Everything looks equally important
❌ Secondary action has same weight as primary
❌ Dense layouts with no breathing room
❌ Important info buried below fold

Mobile-First Checklist

Thumb Zone (Critical)

┌─────────────────┐
│     HARD        │  ← Navigation, settings
├─────────────────┤
│   NATURAL       │  ← Primary content
├─────────────────┤
│   NATURAL       │  ← Primary actions
├─────────────────┤
│    HARD         │  ← Avoid critical actions here
└─────────────────┘

Touch Targets

Minimum: 44×44px (Apple HIG)
Recommended: 48×48px for primary actions
Spacing: ≥8px between targets

Accessibility Review

Contrast Ratios

Element	Minimum	Recommended
Body text	4.5:1	7:1
Large text (18px+)	3:1	4.5:1
UI components	3:1	4.5:1

Screen Reader

Semantic HTML (<nav>, <main>, <button>)
ARIA labels for icons
Logical tab order
Focus visible states

Motor Considerations

No hover-only interactions on mobile
No tiny close buttons
Sufficient time for timed actions

Feedback States

Every interactive element needs:

State	Visual
Default	Base appearance
Hover	Subtle change (desktop)
Active/Pressed	Clear feedback
Focus	Ring or outline
Loading	Spinner or skeleton
Disabled	Muted, no pointer
Success	Green checkmark, toast
Error	Red highlight, message

Current Trends to Consider

2025-2026 Patterns

Bento layouts - Grid-based dashboards
Glassmorphism - Subtle blur effects (use sparingly)
Micro-interactions - Small, delightful animations
Dark mode - Essential, not optional
Variable fonts - For refined typography
Reduced motion - Respect prefers-reduced-motion

Always Timeless

Clean whitespace
Consistent spacing (8px grid)
Clear visual hierarchy
Obvious affordances

Review Output Format

## Design Review: `ComponentName` / `Screen Name`

### 🔴 Critical Issues
1. **[Accessibility]** Button contrast ratio 2.1:1 (needs ≥4.5:1)
   - Fix: Change to `text-gray-900` on `bg-gray-100`

### 🟡 Usability Issues
1. **[Workflow]** 3 taps to start job, could be 1
   - Fix: Add "Start Job" CTA on card in list view

2. **[Feedback]** No loading state on submit
   - Fix: Add spinner via `isLoading` prop

### 🟢 Enhancements
1. **[Polish]** Add subtle scale on card hover
2. **[Delight]** Haptic feedback on checklist completion

### ✅ Good Practices
- Clear visual hierarchy
- Consistent use of design tokens
- Appropriate touch target sizes
