Cameo E2E Bridge : Case Studies

Telecom Industry: Leading Telecom Increases Transparency & Control

Challenge

swisscom logoFor its SME business unit, which covers DSL, VPN and other products, Swisscom uses the custom-built eDASECO application, which was never integrated with the central data warehouse. As a result, only rudimentary reporting mechanisms were available, denying employees to proactively address issues which affected service quality.

To remedy the situation, ARIS PPM from IDS Scheer was installed as the monitoring solution. But the integration with the backend proved to be challenging: the traditional integration approach required middleware changes to be scheduled six months in advance. Apart from the implementation, most of the time was consumed by manual testing and writing updocumentation. Each modification of the backend, changes to the process or any updates to the KPIs caused a considerable effort, consuming time and causing additional cost.

  • The E2E Bridge® allows Swisscom to reach all its business objectives without compromise – and in record time! This is exactly the level of business agility we were looking for.
  • A few days before going live, we had to upgrade our Order Management System. With a traditional approach, such a last minute change would have caused 3-4 months delay. The E2E Bridge® allowed us to go live as originally planned. Markus Witschi

Solution

To accelerate the integration of ARIS PPM with eDASECO, Swisscom selected the E2E Bridge extraction. E2E’s unique Direct Mod approach provided extraordinary flexibility and allowed for quick adaptation in response to rapidly changing backend interfaces. With the new solution based on the E2E Bridge® and ARIS PPM, routine modify usually completed within half an hour.

All changes are now fully documented at all times, in form of standard UML® models, which are automatically tested and can be directly executed. The new system delivers accurate KPIs and graphical reports. Based on a sophisticated drill-down capability, KPIs can be verified effectively. Escalation procedures are triggered automatically if process steps are not performed within predetermined deadlines. The entire project initiative was completed from start to go live in 14 weeks.
