# 👥 User Journey Optimization & Role-Specific Patterns

## 🎯 Journey-First Design Philosophy

### Performance Targets by Role
```typescript
interface RolePerformanceTargets {
  admin: {
    dashboardLoad: '< 2 seconds',
    reportGeneration: '< 5 seconds',
    userManagement: '< 1 second per action',
    systemOverview: '< 1.5 seconds'
  },
  server: {
    orderCreation: '< 30 seconds total',
    productSelection: '< 5 seconds per item',
    tableAssignment: '< 3 seconds',
    customerInteraction: 'seamless, no delays'
  },
  counter: {
    paymentProcessing: '< 10 seconds',
    orderTypeSwitch: '< 2 seconds',
    receiptGeneration: '< 3 seconds',
    queueManagement: 'real-time updates'
  },
  kitchen: {
    statusUpdates: '< 1 second',
    orderPrioritization: 'real-time',
    workflowOptimization: 'continuous',
    communicationDelay: '< 2 seconds'
  }
}
```
