• Maintain dashboards and execution scorecards for SIT and UAT completion, defect aging, and testing throughput.
• Identify risks early and recommend mitigation strategies to protect deployment schedules and operational readiness.

Continuous Improvement & Standardization

• Capture lessons learned from each deployment and improve test scripts, test coverage models, and execution playbooks for future waves.
• Standardize UAT processes across sites to enable repeatable and scalable testing execution across 50+ warehouse operations.
