British Telecom

• Oracle SOA Suite, BPA Suite, IdM Suite, Webcenter Suite

• Composite apps and process integration using Oracle Fusion Middleware with Oracle EBS,

PeopleSoft and Siebel

• One of the world’s largest telecom service provider • High cost of managing and maintaining 400 legacy IT

systems

• Need a consolidated applications that allows to procure

goods and services for 10,000 properties and 5,000

vehicles

Opportunities & Challenges

• Retired 46 legacy apps, increasing ‘right first time’ dramatically increasing user experience scores

• Enterprise level process automation resulting in consolidation of many heterogeneous custom and packaged applications

Costco

• Oracle Imaging and Process Management (I/PM) and Oracle BPEL to automate paper based

document workflow and provides quick access to invoices

• One of the world’s largest membership based retail warehouse chain

• AP dept. processes 30,000 documents a day

• Was manually handling paper based documents

• Re-keying of data, human error, duplication of effort, difficult to track


• Response time reduced from 2–10 days to 1–10 seconds

• Saved $7 million by reducing staff and achieved ROI in less than 12 months

• Improving relationships with key vendors (processing invoices in timely manner, able to tell vendors the exact status of any invoice)

Time Warner Cable

• Oracle SOA Suite to automate provisioning process by orchestrating both legacy billing system

interfaces, and custom developed adapters

• Oracle Rules to Allow biz rule changes by non-dev staff without code/build/deploy/test overhead

• 2nd largest multiple service provider; owns and manages advanced, well-clustered cable systems in the United States

• No Billing/Provisioning process is performed the same way across Divisions (even amongst divisions using the same systems).

• Lack of robust billing system vendor developed automation interfaces


• Application to allow Business Class Phone customers to manage their accounts online

• Allows a user to upgrade their account from RoadRunner standard to premium

• Increased revenue by 15% for the business through reduced call center call volume and elimination of customer cancellation opportunities
