Review KPIs, performance measures and business-case outputs to ensure they are consistent with the underlying data and proposed solutions
Identify, document and prioritise defects and issues in a clear and reproducible format
Work closely with Engineering, Optimisation and Delivery teams to investigate issues and validate fixes
Re-test solutions following changes and contribute to regression testing ahead of releases and customer go-lives
Build and maintain a structured library of test cases and disruption scenarios for different customer environments
Work with customer stakeholders during implementations to understand their requirements, validate outputs and capture feedback
Analyse operational data and use evidence to support testing conclusions and recommendations
