Design & Architecture

‣ Manage third -party supplier relationships where legacy data extraction is performed by incumbent system vendors.

Quality, Risk & Compliance

‣ Maintain and actively manage the Data Migration Risk Register, ensuring all risks have mitigation plans and owners.

‣ Ensure all data handling practices comply with GDPR, public sector data governance frameworks, and client-specific information security policies.

‣ Apply data quality scoring methodologies to baseline and track improvement in data completeness, accuracy, consistency and uniqueness across all migration objects.

‣ Coordinate with the client's internal audit and data assurance teams to provide evidence of data integrity throughout the migration lifecycle.

‣ Support post-go-live hypercare activities including data correction, balance adjustments and retrospective historical record validation.
