Case Study: Helsana achieves enterprise-wide data quality management with BiG EVAL

Helsana runs 17,000 automated data quality checks a day with BiG EVAL

Helsana, Switzerland's leading health and accident insurer, faced a challenge in verifying the accuracy of millions of records within its new data warehouse. Their initial manual, spreadsheet-based solution for data quality checks was fragile, difficult to maintain, and relied heavily on a few specialists. They turned to the vendor BiG EVAL to implement an automated and scalable data quality management solution.

BiG EVAL provided a technology-independent platform that automated data quality checks using reusable patterns. This solution grew to run 17,000 automated checks daily, catching errors early and providing a measurable view of data quality. The implementation delivered significant results, including a seamless migration of all checks during a full data warehouse technology change with zero test cases rewritten, freeing specialists for higher-value work and restoring company-wide confidence in their data.
