Empowering Customers Through a Digitized Prepaid Billing Application
This case study covers the redevelopment and performance testing of a prepaid billing application designed to give customers greater control over their energy consumption and spending. As part of a digitization initiative, the solution spans both a web portal and a native mobile application, with enhanced user experience and robust performance.
Challenges
Transaction Failure and SLA Not Met
Observation: certain transactions failed and SLA metrics weren't achieved during testing. Resolution: the application was fine-tuned to address the underlying performance bottlenecks.
CPU Load Imbalance
Observation: CPU 1 usage reached 100% while CPU 2 remained idle during steady state at full load (1,000 virtual users). Resolution: investigated and resolved load-balancing issues to ensure even distribution across CPUs.
Cycle 2 Run 5 Failure
Observation: response time dropped below 1 second due to login failures for 415 users or possible application downtime during execution. Resolution: analyzed application logs and server availability to address the root cause.
Results
- Enhanced User Experience: Streamlined interfaces on both platforms enabled intuitive control over energy consumption and spending.
- Improved Application Robustness: Thorough testing identified and resolved performance bottlenecks, with deployment readiness ensured through pre- and post-deployment testing.
- Scalable Architecture: Redesigned backend capable of handling future user growth.
- Seamless Feature Rollout: Phased deployment minimized risk and ensured incremental feature testing.
The redevelopment of the prepaid billing application successfully empowered customers with digitized control over their energy usage and expenses. Rigorous performance testing ensured the application's stability and scalability across its web and mobile platforms, even under high concurrent user loads. By adopting a phased rollout strategy and iterative testing cycles, the project delivered a robust, user-friendly solution aligned with the goals of the digitization initiative.
