Feedback Mechanisms
Timing, clarity, and modality of effective system feedback.
System Status Visibility: Keep users informed about what’s happening through clear, immediate feedback. Never leave users wondering if their action worked.
Financial systems involve high-stakes actions where users need confidence that operations completed successfully. Traditional enterprise systems often fail by:
This creates user anxiety and distrust:
Financial platforms especially need to communicate clearly because mistakes have real monetary consequences.
Stripe Dashboard exemplifies system status visibility through real-time feedback, clear confirmations, and transparent error handling.
1. Immediate Feedback on All Actions
2. Toast Notifications (Non-Blocking)
3. Inline Status Indicators
4. Detailed Error Messages
5. Progressive Loading States
6. Confirmation Dialogs for Destructive Actions
7. Background Process Indicators
8. Webhooks & Real-Time Updates
| Metric | Before Clear Feedback | With Stripe-Style Feedback | Improvement |
|---|---|---|---|
| User Confidence (Survey) | 3.1/5 | 4.8/5 | +55% improvement |
| Duplicate Actions | 12% of transactions | 1% of transactions | 92% reduction |
| ”Did it work?” Support Tickets | 18% of all tickets | 2% of all tickets | 89% reduction |
| Task Completion Time | 45 seconds avg | 22 seconds avg | 51% faster |
| User Satisfaction | 3.5/5 | 4.6/5 | +31% improvement |

Accessibility
Screen reader announcements for dynamic status changes.
Visual Design
Color, typography, and icons for clear status communication.
When you use the Human Standards MCP server, these rules enforce feedback patterns:
feedback-immediate-required
// Triggered when actions lack immediate feedback{ severity: 'warning', rule: 'feedback-immediate-required', message: 'User actions should provide immediate feedback (<1 second)', recommendation: 'Show loading state immediately, then success/error notification', reference: '/interaction-patterns/feedback.md'}feedback-success-confirmation
// Checks for success confirmations{ severity: 'info', rule: 'feedback-success-confirmation', message: 'Successful actions should confirm completion', recommendation: 'Use toast notification or inline message to confirm success', reference: '/interaction-patterns/feedback.md'}defensive-specific-errors
// Validates error message specificity{ severity: 'error', rule: 'defensive-specific-errors', message: 'Generic error messages like "Error occurred" are not helpful', recommendation: 'Provide specific error with actionable recovery steps', reference: '/decision-making-errors/defensive-design.md'}feedback-loading-states
// Checks for loading indicators{ severity: 'warning', rule: 'feedback-loading-states', message: 'Async operations should show loading state', recommendation: 'Use skeleton loaders or spinners to indicate progress', reference: '/interaction-patterns/feedback.md'}// Get relevant heuristics for feedback patternsconst systemStatus = await mcp.callTool('get_heuristic', { id: 'H1' });// Returns: Visibility of system status - loading states, feedback, progress

| <0.1s | Instant actions (button press, typing) | Visual state change only |

| 1-3s | Medium operations (API calls, calculations) | Loading overlay + progress indicator |
| 3-10s | Slow operations (file uploads, batch processing) | Progress bar with percentage + time estimate |
| >10s | Long operations (reports, exports) | Background task + email notification when done |
| Action Type | Feedback Pattern | Example |
|---|---|---|
| Create | Success toast + show created item | ”Payment created successfully” |
| Update | Optimistic UI + success toast | ”Customer updated” (changes visible immediately) |
| Delete | Confirmation dialog + success toast + undo option | ”Customer deleted” with 5s undo window |
| Error | Specific error message + recovery action | ”Card declined. Ask customer to try another card.” |
| Background | Progress notification + completion alert | ”Export started. We’ll email you when it’s ready.” |
