Case Study: Leading Telecom Operator achieves faster 4G rollouts and 30% quicker performance bottleneck detection with Hexaware

Leading Telecom Operator - Customer Case Study

Leading Telecom Operator is a fast-growing European telecom provider with 14 million customers across nine countries that needed faster time-to-market for 4G rollouts, lower risk from single-release deployments, cost optimization, and quicker root-cause analysis of performance issues across many native and third‑party integrations. Hexaware was engaged to address these challenges using an Agile Performance Testing approach leveraging open-source load testing (JMeter) and AppDynamics APM.

Hexaware implemented an Agile Scrum testing model with JMeter-driven load tests, AppDynamics agents (including DB and JavaScript/RUM agents) and custom performance dashboards for rapid bottleneck analysis. The solution improved process maturity and CI-driven sprints, enabled reusability of test script components, reduced time to identify performance issues by 30%, lowered cost-of-failure through earlier detection, sped up rollout of the BIG 5 4G applications, and delivered better end-user experience and increased profit.
