Led a Business Unit Performance Review focused on QA metrics to track operational results and service quality. Utilized the PDCA cycle (Plan–Do–Check–Act) to identify recurring issues revealed by RCAT (Root-Cause Analysis of Tickets), plan corrective actions, test solutions, and verify their impact. Implemented targeted process changes — such as better ticket categorization, faster escalation paths, and proactive knowledge-sharing — which reduced recurring issues and improved overall QA performance and customer experience.
