|
|
2. ✅ Processing integration events from external systems (HIS/Lab/Radiology/Pharmacy)
|
|
3. ✅ Automatically completing journey stages based on events
|
|
4. ✅ Triggering stage-specific surveys when stages complete
|
|
5. ✅ Sending surveys via SMS/WhatsApp/Email (console backend)
|
|
6. ✅ Collecting and scoring survey responses
|
|
7. ✅ Identifying negative feedback for action creation (Phase 6)
|
|

## 🔑 Critical Business Logic Implemented
|
|
|
|
### 1. Journey-Stage-Survey Linkage ✅
|
|
Each journey stage can trigger a specific survey when completed via integration event.
|
|
|
|
### 2. Event-Driven Stage Completion ✅
|
|
All stage completions happen via InboundEvent processing (Celery).
|
|
|
|
### 3. Automatic Survey Creation ✅
|
|
When stage completes and `auto_send_survey=True`, survey is created and sent.
|
|
|
|
### 4. Multi-Channel Delivery ✅
|
|
Surveys sent via SMS, WhatsApp, or Email based on configuration.
|
|
|
|
### 5. Score Calculation ✅
|
|
Supports average, weighted average, and NPS scoring methods.
|
|
|
|
### 6. Negative Feedback Detection ✅
|
|
Scores below threshold flagged for action creation (Phase 6).
|
|
|
|
### 7. Audit Trail ✅
|
|
All events, stage completions, and survey sends logged.
