Case Study: a South African utility company achieves 100% data validation with QuerySurge and Ntokoto Technology Group

QuerySurge’s Partner Ntokoto Technology Group Assists Global Energy Company with Validating 100% of their Data

The customer, a South African utility company, was facing significant data quality issues. Their existing validation process, reliant on Excel macros and data sampling, was leading to long test cycles, missed deadlines, and bad data in production. This outdated methodology was incompatible with a continuous testing model. They engaged QuerySurge's partner, Ntokoto Technology Group (NTG), to address these challenges with the QuerySurge automated data testing solution.

Ntokoto Technology Group implemented QuerySurge to design a full suite of automated tests, validating 100% of the company's data. The solution involved streamlining the ETL process and integrating it with Azure DevOps to create efficient CI/CD pipelines. This allowed QuerySurge to validate over 5,000 data points with each release, dramatically improving test coverage and speed. The business users received immediate notifications of any data issues, which was critical for accurate reporting and decision-making, leading to plans for an enterprise-wide rollout.
