## Executive Summary

### Coverage Statistics

| Metric | Count | Notes |
|--------|-------|-------|
| **Total Modules Documented** | 103 | Including all submodules |
| **Total Use Cases** | 509 | Across 15 major categories |
| **WPF View Files** | 951+ | Located in `src/centron/Centron.WPF.UI/Modules/` |
| **ViewModels Identified** | 180+ | With extensive reuse patterns |
| **Properties Explicitly Documented** | 25+ | Bindable properties with UI mapping |
| **Commands Explicitly Documented** | 5+ | ICommand implementations |

### Mapping Status Overview

| Status | Symbol | Count | Percentage | Description |
|--------|---------|-------|------------|-------------|
| **Fully Mapped** | ✅ | 95+ | ~92% | Use case has clear UI elements and ViewModel properties |
| **Partially Mapped** | ⚠️ | 6+ | ~6% | Use case documented but some UI elements unclear |
| **Needs Investigation** | 🔍 | 2+ | ~2% | Ambiguous mapping or missing information |
| **Unmapped** | ❌ | <1 | <1% | No clear connection found |

### Key Findings

1. **Strong Documentation**: USE_CASES.md already includes WPF module paths, ViewModels, and Controllers for each module
2. **MVVM Pattern**: Extensive ViewModel reuse across modules with clear separation of concerns
3. **Wizard-Based Workflows**: Many billing and import modules use multi-step wizard patterns
4. **Comprehensive Property Documentation**: Properties include type information, default values, and code references
5. **Integration Points**: External APIs (FinAPI, GLS, Shipcloud, MSP systems) well-documented

## Summary of Unmapped Items

### UI Elements Without Clear Use Case Documentation ⚠️

1. **Advanced Search Features**: Some modules have complex search dialogs not explicitly documented as use cases
2. **Context Menus**: Right-click context menu actions not fully documented
3. **Keyboard Shortcuts**: Hotkey mappings not included in use case documentation
4. **Drag-and-Drop**: Some drag-and-drop operations exist but aren't documented as separate use cases

### Use Cases Needing Investigation 🔍

1. **MyCentron Telefonate (11.3)**: Marked as "Nicht implementiert" (Not implemented) in USE_CASES.md
2. **Some Wizard Intermediate Steps**: Some wizard pages are structural separators without explicit use cases

### Discrepancies ❌

1. **No significant discrepancies found**: USE_CASES.md is highly comprehensive and accurate

---

## Recommendations for Investigation 🔍

### Priority 1: Clarify Implementation Status

1. **MyCentron Telefonate (11.3)**: Confirm if this module is truly not implemented or if documentation is outdated
2. **Password Manager Modules (12.x)**: Marked as deprecated - verify if still in use or should be removed

### Priority 2: Document Missing UI Patterns

1. **Context Menu Actions**: Document right-click context menu use cases
2. **Keyboard Shortcuts**: Add hotkey mappings to use case documentation
3. **Advanced Search**: Document complex search scenarios

### Priority 3: Enhance Wizard Documentation

1. **Separator Pages**: Clarify purpose of separator wizard pages
2. **Navigation Logic**: Document conditional page enabling logic

---

## Appendix A: WPF Module Structure

### Common UI Patterns

1. **Master-Detail Layout**: 250-300px list on left, detail form on right
2. **Wizard-Based Flows**: Multi-step processes with WizardHelperViewModel
3. **Tab-Based Navigation**: Tabs for different aspects (General, Contacts, History, etc.)
4. **Grid-Based Lists**: DevExpress GridControl for all data lists
5. **Ribbon Integration**: Most modules implement IRibbonControlModule variations

### Common ViewModel Properties

- `IsLoading` / `IsProcessing`: Busy indicators
- `SelectedItem` / `SelectedItems`: Selection tracking
- `SearchText` / `FilterText`: Quick search/filter
- `CanSave` / `CanDelete`: Command enablement
- `IsDirty` / `HasChanges`: Change tracking

### Common Commands

- `SaveCommand`: Persist changes
- `DeleteCommand`: Remove items
- `RefreshCommand`: Reload data
- `ExportCommand`: Export to Excel/PDF
- `NewCommand`: Create new item

---

## Appendix B: ViewModel to View Mapping Convention

**Pattern**: `{Name}ViewModel.cs` ↔ `{Name}View.xaml`

**Examples**:
- `AutomatedBillingViewModel.cs` ↔ `AutomatedBillingView.xaml`
- `CrmMainViewModel.cs` ↔ `CrmMainView.xaml`
- `PaymentsViewModel.cs` ↔ `PaymentsView.xaml`

**Exceptions**:
- Settings pages use dynamic loading
- Dialog ViewModels may not have dedicated views
- Some shared components use generic views

---

## Appendix C: Rights Mapping

**Pattern**: Each module has associated rights constant from `UserRightsConst.cs`

**Examples**:
- `UserRightsConst.Sales.AUTOMATED_BILLING` → Vertragsabrechnung (1.1)
- `UserRightsConst.Sales.Provision.PROVISION_EVALUATION_MODULE` → Provisionsauswertung (1.3)
- `UserRightsConst.Finances.PAYMENTS` → Zahlungseingang (5.7)
