Helsana, a major Swiss health and accident insurer, faced challenges with maintaining its complex in-house data quality testing methods for its Teradata data warehouse. The existing solution was difficult to maintain and expand. To professionalize its data quality management, Helsana decided to implement the BiG EVAL data quality suite to standardize and automate its testing processes.

The vendor, BiG EVAL, provided a robust and intuitive platform that centralized test case administration. With support, Helsana quickly recreated all its test cases in the new system, enabling fully automated, continuous quality checks across the organization. The implementation of BiG EVAL stabilized data quality, identified issues proactively, and integrated deeply into Helsana's processes. This resulted in thousands of automated tests running regularly, supporting critical migration projects, and replacing outdated manual solutions like those in the accounting department.
