Case Study: RWE Supply & Trading achieves more robust, lower-cost, easier-to-change trading systems with CAST

How Software Measurement To Improve The Robustness And Resilience Of Trading Systems

RWE Supply & Trading (RWEST) is RWE Group’s global wholesale energy trading arm, managing power, gas, coal, oil, emissions and renewables across multiple markets. Facing rapidly growing systems complexity and the high cost and risk of software failures, RWEST needed a way to improve structural code quality so its trading platforms would be more robust, easier to change and cheaper to operate over time.

RWEST implemented CAST’s Application Intelligence Platform to perform structural software-quality analysis alongside traditional testing. The platform revealed architectural and performance issues before production, enabling cleaner, simpler systems, faster maintenance and measurable cost savings—giving RWEST greater confidence to execute business-critical strategies and adapt to changing markets.
