Case Study: Global Telecom Service Provider achieves Siebel stability and 87.5% testing time savings with Tricentis

Global telecom service provider improves Siebel stability and efficiency through automated testing

One of Australia’s leading telecom providers (servicing 5.3 million customers) needed to upgrade its mission‑critical Siebel CRM from 7.5.3 to 8.1.1. The project required comprehensive end‑to‑end testing across Siebel Classic and OpenUI plus integrations with Java, PuTTY, file processing and Oracle DB; downtime was unacceptable and previous automation efforts had failed, making manual testing infeasible within the program timeline.

The company selected Tricentis Tosca for full‑stack, model‑based automation and implemented risk coverage optimization, Jenkins‑driven distributed execution (20 VMs), automated test‑data generation and custom reporting. The result: 450 regression cases automated, regression execution cut from 270 to 22 hours (≈92% saving), test‑data time per order reduced from 25 to 10 minutes (≈60% saving), total manual effort reduced from 312 to 39 hours, and an overall program savings of 87.5% with significantly accelerated time‑to‑value.
