4. ✅ Monitoring Setup - Good placement
5. ⚠️ Documentation - Could start earlier in parallel
6. ✅ Production Hardening - Appropriate
7. ✅ Compliance - Good placement
8. ✅ Enhancements - Appropriate for last

Recommended Adjusted Order

1. Testing Framework Setup (NEW - must be before testing)
2. Security Audit (existing)
3. Complete Testing (existing - now possible with framework)
4. External Integrations (existing)
5. Monitoring Setup (existing)
6. Documentation (existing - can run in parallel)
7. Production Hardening (existing)
