Case Study: NRG Energy achieves faster, more accurate payroll testing with EPI-USE Labs Variance Monitor

Variance Monitor™ ensures accurate data NRG and GenOn discover real power

NRG Energy, a Fortune 500 energy provider, faced a significant data integration and testing challenge following its acquisition of GenOn Energy. The merger required combining disparate payroll and timekeeping systems, a process fraught with risk and the potential for error. To mitigate this, NRG partnered with EPI-USE Labs and utilized their Variance Monitor solution to ensure a smooth and accurate transition.

EPI-USE Labs' Variance Monitor enabled NRG to run payroll simulations and compare results with 100% accuracy without processing a live payroll, drastically speeding up the testing phase. The solution provided detailed statistical analysis and reporting, which saved considerable time and effort, allowing the project to be completed on time and with one fewer parallel test run than originally planned. The implementation by EPI-USE Labs was so successful that NRG continues to use Variance Monitor for ongoing production support and data validation.
