Monitor defect trends, quality metrics, and test coverage to drive continuous quality improvements.
Provide regular status reporting, risk assessments, mitigation plans, and executive-level quality dashboards.
Ensure compliance with release readiness criteria and quality gates.

Leadership & Stakeholder Management

Lead and mentor testing teams, providing guidance on Mainframe testing best practices, standards, and methodologies.
Collaborate closely with Business Analysts, Developers, Architects, Production Support Teams, SMEs, and Business Stakeholders.
Facilitate test planning workshops, defect review meetings, status meetings, and stakeholder communications.
Drive cross-functional coordination to resolve dependencies, issues, and project risks.

Release & Production Support

Ensure successful completion of go-live activities, smoke testing, and production reconciliation.
Participate in audit, compliance, and regulatory testing activities when required.
