 ## Property Management System (PMS)
 
+## Post-Implementation Support Phase
+
+**Phase Duration**: 3 months (2026-10-01 to 2026-12-31)  
+**Key Deliverables**: Stabilization, Optimization, Knowledge Transfer
+
+### Enhanced Features for Production Support
+- ✅ Comprehensive health monitoring and observability
+- ✅ Performance optimization configurations
+- ✅ Centralized logging with rotation
+- ✅ Prometheus metrics integration
+- ✅ Automated startup and health check scripts
+- ✅ Operational documentation and troubleshooting guides
+
+### Quick Start (Post-Implementation)
+```bash
+# Start all services in proper order
+./scripts/startup_order.sh
+
+# Check system health
+./scripts/health_check.sh
+
+# View monitoring endpoints
+curl http://localhost:8888/actuator/health  # Configuration Service
+curl http://localhost:8761/actuator/health  # Discovery Service  
+curl http://localhost:9000/actuator/health  # Gateway Service
+curl http://localhost:8070/actuator/health  # User Management Service
+```
+
+### Documentation
+- [Operations Guide](docs/OPERATIONS_GUIDE.md) - Comprehensive operational procedures
+- [Monitoring Guide](docs/MONITORING_GUIDE.md) - Monitoring and troubleshooting procedures  
+- [Knowledge Transfer](docs/KNOWLEDGE_TRANSFER.md) - Complete system knowledge transfer
+- [Performance Optimization](docs/PERFORMANCE_OPTIMIZATION.md) - Performance tuning guide

 ## 1. System Architecture Overview
 1. System Architecture Overview
 Based on the UML model we've developed, I propose a modern, cloud-native, microservices-based architecture for the PMS. This approach will allow for better scalability, maintainability, and the ability to deploy updates to individual components without affecting the entire system.
