Risk Accountabilities

• Apply enterprise quality engineering frameworks, software delivery controls, security requirements and regulatory expectations within assigned scope.
• Maintain traceability from requirements to test cases, automated tests, execution results, defects and readiness evidence.
• Identify, document, manage and **escalate** quality, operational, data, environment and implementation risks, including non-standard or high-risk activities.
• Use quality metrics and trend analysis to evaluate coverage, defect health, automation effectiveness and release readiness; communicate concise, decision-oriented reporting.
• Conduct reviews of test strategies, scenarios, scripts and evidence to confirm completeness, reusability, maintainability and compliance.
• Protect customer and Bank information by following access, test-data masking, segregation-of-duties and evidence-retention requirements.
• Improve delivery efficiency by eliminating redundant testing, increasing automation, strengthening reusable assets and addressing recurring defect patterns.
• Support implementation validation and post-implementation checks to confirm processing integrity and production stability.

Team Accountabilities
