- System Integration Testing (SIT)
- User Acceptance Testing (UAT)
- Mock Conversions and Cutover cycles
- Troubleshoot and resolve integration defects across environments
- Validate end-to-end data integrity and system interactions
- Support cutover planning and sequencing for middleware objects
Hypercare & Production Support- Provide post-go-live support for integration defects and performance issues
- Monitor middleware performance, message queues, and interface failures
- Support stabilization and defect triage during hypercare phase
Cross-Functional Collaboration- Functional teams to validate business process integration
- ABAP developers for custom interface remediation
- Data migration teams for data flow consistency
- Basis/infrastructure teams for environment and transport management
