## 📋 Remaining Work

### Controllers Needed (6)
1. **QMSDocumentController** - Full CRUD for documents
2. **QMSAuditController** - Audit & findings management
3. **QMSObjectiveController** - Objectives & progress
4. **QMSRiskController** - Risk management
5. **QMSCalibrationController** - Calibration tracking
6. **QMSManagementReviewController** - Management reviews

### Views Needed
- Full CRUD views for each of the 6 controllers above
- Forms for creating/editing records
- Detail views with related data
- List views with filtering

### Dashboard Widgets (Optional Enhancement)
Could add specific widgets to main ERP dashboard:
- Overdue Audits widget
- Open NCRs widget
- Overdue CAPAs widget
- Document Expiry Alerts widget
- Objectives Progress widget
- High-Risk Items widget

## 🚀 Next Steps

1. **Create remaining controllers** (QMSDocumentController, QMSAuditController, etc.)
2. **Build CRUD views** for each module
3. **Test workflow**: Document approval, audit completion, finding CAPA tracking
4. **Optional**: Create dashboard widgets
5. **Optional**: Build reporting views (audit summary, risk heat map, objectives dashboard)
