Case Study: a leading global private equity firm improves ETL and BI data validation with QuerySurge

Global Private Equity Firm Seeks Data Testing Guidance

A leading global private equity firm faced significant challenges in its data quality efforts. Its manual testing process was unable to verify the millions of data points produced by its ETL process, leading to untested data in its MicroStrategy BI reports and a loss of stakeholder confidence. The firm sought guidance on an automated solution and brought in QuerySurge for its expertise.

The solution from QuerySurge involved analyzing the existing testing strategy and implementing its automated data quality platform. QuerySurge helped create data mapping documentation and developed automated tests for each leg of the ETL process and the MicroStrategy reports. This provided complete end-to-end validation and integrated with Azure DevOps. The result dramatically reduced testing time from several days to just hours, allowing the QA team to expand test coverage and ensure reliable data for decision-making.
