From Manual Checks to Trusted Data: Transforming Enterprise Data Integrity for a Leading Insurance Provider 

Background: 

A major U.S.-based insurance provider faced persistent data quality challenges across its enterprise systems. With complex data pipelines spanning mainframe, cloud, and in-house applications, the organization struggled with manual validation, delayed deployments, and high QA costs. 

To support timely business decisions and maintain compliance, the insurer needed a robust, automated approach to data quality assurance, one that could scale with its growing digital ecosystem. 

Challenges: 

• Data accuracy could not be confidently confirmed from flat file sources. 

• Manual sampling led to high effort, delays, and inconsistent validation. 

• Low test coverage resulted in reprocessing cycles and costly QA inefficiencies. 

• Complex data transformations lacked integrity checks, introducing risk to end-user outputs. 

• Multiple legacy and modern platforms made automation more difficult to implement.
