## Known Limitations & Mitigations
|
|
|
|
### Limitation 1: Vector Database Size
|
|
**Description:** Milvus configured for 1M embeddings
|
|
**Impact:** After 1M solutions stored, performance degradation expected
|
|
**Mitigation:** Archive old solutions, implement sharding strategy
|
|
**Timeline:** Expected after 2 years of operation (assuming 1,300 solutions/day)
|
|
|
|
### Limitation 2: LiteLLM Token Cost
|
|
**Description:** Using GPT-3.5-turbo at ~$0.001 per 1K tokens
|
|
**Impact:** $0.02-0.05 per ticket analysis (depending on ticket size)
|
|
**Mitigation:** Implement token budget limits, use cheaper models for simple issues
|
|
**Timeline:** Monitor costs after first 30 days
|
|
|
|
### Limitation 3: Workflow Parallelization
|
|
**Description:** n8n free tier limited to 5 concurrent workflows
|
|
**Impact:** High-volume scenarios (>5 simultaneous tickets) will queue
|
|
**Mitigation:** Upgrade to n8n Pro for unlimited parallelization
|
|
**Timeline:** Evaluate after first month of operation
|
|
|
|
### Limitation 4: Email Delivery Reliability
|
|
**Description:** Email sending depends on Freescout's mail provider
|
|
**Impact:** Email delivery may be delayed 5-30 minutes
|
|
**Mitigation:** Implement retry logic in Workflow B, notify users of delays
|
|
**Timeline:** Standard limitation of email infrastructure
|
|
|

|
|
|
|
## Risk Assessment & Mitigation
|
|
|
|
### High Risk: Infrastructure Failure
|
|
**Risk:** Docker containers crash
|
|
**Impact:** System offline, tickets not processed
|
|
**Mitigation:**
|
|
- [ ] Implement container restart policies
|
|
- [ ] Set up monitoring alerts
|
|
- [ ] Create incident response runbook
|
|
- [ ] Weekly health check automation
|
|
|
|
### High Risk: Data Loss
|
|
**Risk:** PostgreSQL or Milvus loses data
|
|
**Impact:** Knowledge base lost, audit trail incomplete
|
|
**Mitigation:**
|
|
- [ ] Daily automated backups
|
|
- [ ] Off-site backup storage
|
|
- [ ] Recovery time objective (RTO): 1 hour
|
|
- [ ] Recovery point objective (RPO): 1 day
|
|
|
|
### Medium Risk: Performance Degradation
|
|
**Risk:** Vector search becomes slow
|
|
**Impact:** Workflow C takes >10 minutes
|
|
**Mitigation:**
|
|
- [ ] Monitor search latency
|
|
- [ ] Implement caching strategy
|
|
- [ ] Archive old vectors quarterly
|
|
|
|
### Medium Risk: API Rate Limiting
|
|
**Risk:** LiteLLM or Freescout API rate limits exceeded
|
|
**Impact:** Workflow processing delays
|
|
**Mitigation:**
|
|
- [ ] Implement request queuing
|
|
- [ ] Add retry with exponential backoff
|
|
- [ ] Monitor API quota usage
|
|
|
|
### Low Risk: Integration Breaking Changes
|
|
**Risk:** Freescout API updates incompatibly
|
|
**Impact:** Webhook receivers or API calls fail
|
|
**Mitigation:**
|
|
- [ ] Subscribe to API changelog
|
|
- [ ] Implement API versioning
|
|
- [ ] Quarterly integration testing
|
|
