A word from Türk Telekom Group

  • “With emerging technologies creating a heavy demand on legacy systems, we needed to optimize product lifecycle management for several hundred SOA initiatives to mitigate negative effects on customer loyalty. Oracle Enterprise Repository 11g enabled us to achieve our goals. The solution met all of our primary business drivers and helped us to realize technological transformation and gain new customer-facing business capabilities.” – Turan Ozen, Manager of Integration Architecture Department, Türk Telekom Group

  • Adapt services and processes to meet rapidly changing telecommunications market requirements―such as consumer demand for triple-play offerings and mobile payment systems―with role-based visibility into numerous service-oriented architecture (SOA) assets
  • Aggregate data on service-oriented architecture (SOA) asset lifecycle status to obtain, at all times, a clear picture of which SOA services exist and what the status of each service is—in production, in development, or retired—to better align these services with business demands
  • Optimize the development of several hundred SOA services by identifying the dependencies among numerous kinds of middleware and enterprise services deployed within the organization, and determining the impact of change
  • Monitor the value of SOA initiatives to enable fast responses to situations that might affect the wellbeing of the enterprise and its stakeholders


  • Provided comprehensive insight into the impact of several hundred SOA initiatives with Oracle Enterprise Repository 11g to increase customer-facing business capabilities, such as offering new communications products to consumers, based on trend data and market analytics
  • Established complete-service, lifecycle management by governing process, service, and asset lifecycles—from design to deployment and consumption—in production environments to meet consumer needs, such as by bundling mobile and landline services in converged communications products
  • Realized a significant decrease in time to market for new services and other SOA assets—an improvement of between 25% and 70%—thanks to streamlined data flows, improved business rules, and optimized human interactions, which increased customer loyalty and the company’s ability to rapidly respond to marketplace requirements
  • Used Oracle SOA Suite 11g’s real-time decision component, coupled with Oracle Business Activity Monitoring 11g to improve anticipating future demands and responding effectively to customer needs by analyzing statistics and identifying trends through dashboards
  • Enabled developers to spend more time on modeling business processes and less on coding proprietary application programs by establishing platform-independent services, especially important for product offerings that require shared product and customer data
  • Minimized business risks—such as unfulfilled service level agreements and poor product performance—by ensuring that all services and assets promoted to customers meet corporate standards
  • Realized a short-term return on investment of 42%, mainly by saving on development costs
  • Used Oracle Enterprise Repository 11g’s workflow automation capabilities to streamline the migration from Excel-based legacy service repositories to SOA-based asset types
  • Leveraged the migration to review all data to improve data quality
  • Adopted best practices for service governance defined by Oracle’s Global Enterprise Architecture Program (GEAP) and Oracle Unified Methodology (OUM) to enable fast setup of new services, substantially increasing business agility
  • Achieved high performance across disparate systems, enabling seamless deployment of 250 services across 30 applications that handle 5,000,000 daily transactions, on average

Implementation Process

Türk Telekom Group relied on the expertise of Oracle Consulting to realize the deployment. Adopting Oracle Enterprise Repository’s and SOA Governance’s best practices defined by GEAP and OUM, Oracle Consulting customized it Oracle Enterprise Repository with required asset-type definitions and customized workflows to support service lifecycle requirements. Oracle Consulting used Oracle Enterprise Repository’s workflow capabilities to support the migration from the legacy service repository in Excel to new asset types in Oracle Enterprise Repository. In this migration process, application owners were able to review and approve the automatically-converted information.
