Case study

The challenge

A U.K.-based public transportation company grappled with its aging Oracle integration platform. At capacity and facing supportability issues, the system itself wasn’t scalable and the invoice processing system could address only one invoice at a time. The result was a significant backlog. When the company’s incumbent vendor couldn’t successfully upgrade its Oracle platform, it turned to Cognizant.

Our approach

In the design phase, we divided the project into five workstreams and conducted workshops for each. The goal was to develop a clear roadmap for merging the five streams into two during the execution phase. We built a standardized service-oriented architecture and business process management integration platform, as well as upgraded the legacy system to Oracle 12c. 

The upgrade provided a cloud-enabled platform for hybrid integrations, with cloud, external partner and on-premises applications. New capabilities, such as service virtualization, process orchestration and monitoring, and partner integration, were also included. Throughout the engagement, Cognizant evaluated and implemented capabilities beyond the original scope that would provide a true transformation to the digital era. These included addressing application programming interface management, which we believed was critical, and designing the platform with a placeholder for future implementations. After completing the project, the company engaged Cognizant to provide ongoing platform support. We provide continuous and point-to-point solutions using a DevOps model.

Oracle upgrade reduces time to market and enables enterprise scalability

The Oracle platform upgrade reduces time to market for new project integrations by 20 to 30 percent and automates manual invoice reconciliation processes. This eliminates backlog and significantly improves invoice processing performance. The new, high-performance scalable platform supports approximately five million transactions.
