Overview
The client is a leading mutual insurance provider serving thousands of policyholders across the U.S. They are a trusted regional leader in personal and business insurance. Facing an ambitious IT transformation, they partnered with TestingXperts to ensure data accuracy, consistency, and regulatory compliance during core system upgrades and a large-scale Power BI migration.
Challenges
The insurer’s transformation was ambitious and multi-layered. The complexity of the data landscape meant that traditional, ad-hoc validation would not be enough. Key challenge areas included:
Frequent Database Modifications
Business Rule Validation
Newly introduced, population-based and conditional business rules required meticulous validation to prevent compliance gaps and incorrect data-driven decisions.
BI Report & Cube Accuracy
Analytical reports and cubes had to be validated at a granular level to ensure accurate measures, KPIs, and aggregations aligned with business and regulatory expectations.
ETL Job Migration
Migrating ETL jobs from legacy platforms introduced risks around data mismatches, transformation errors, and loss of critical information.
Power BI Migration
Moving from legacy BI platforms to Power BI demanded end-to-end validation of data accuracy, visualization logic, drill-down behavior, and usability for business users.
