              •   Detect potential service degradations before they impact customers, and understanding which
                 problems are affecting the customer experience
              •   Increase marketing and up-sell capabilities by proactively monitoring behavior
              •   Control costs and increase organizational efficiency by focusing on services that are important to
                 the customer
              •   Improve customer retention through differentiation on quality in the marketplace
              •   Drive true customer-centric business through better customer understanding across the organization

            3.7.4.4.2  WebSphere
            IBM’s WebSphere product family provides open standards–based communications and integration
            infrastructure for application development spanning from the enbedded space to the enterprise. Most
            well known are the WebSphere Application Server products. These J2EE platforms provide for ser-
            vice-oriented archictecture (SOA) application development using Web Services, Enterprise Java Beans
            (EJBs), database connections and support extensions for Struts, AJAX, DoJo, JSR-168 Portlets, SSL
            (Secure Socket Layer), SOAP (Simple Object Access Protocol), XML, XSD (XML Schema Definition),
            WSDL  (Web  Services  Description  Language),  JDBC  (Java  Database  Connection),  BPEL  (Business
            Process Execution Language), and ESB (Enterprise Service Bus). Message queuing infrastructure (MQ
            Series and MicroBroker (aka Lotus Expeditor Client) allow for reliable messaging infrastructures to
            support publish/subscribe-based communications. The WebSphere Process Server provides work flow
            for business processes, while WebSphere Portal Server provides collaborative tools for a rich, personal-
            ized user experience.

            3.7.4.4.3  IBM and SOA
            Service-oriented architecture (SOA) enables separation of functions as services with public interfaces
            that enable integration without exposing the actual implementation of functions or database design.
            This has the major advantage that companies can continue to refine the functions providing services to
            improve performance and/or to improve how data is processed without breaking the public interfaces
            supported by the service layer. By implementing a service-oriented architecture, companies can:
              •   create composite business processes through legacy parts consolidation
              •   adapt to change through improved flexibility and distribution/separation of functions
              •   automate business processes and be more responsive to customer needs
              •   interconnect business processes for improved, more timely interaction
              •   lower development cycles and costs
            Service-oriented architecture follows four life cycle phases:

              •   Model: collect and analyze business requirements and processes to understand producer/con-
                 sumer interaction patterns.
              •   Assemble: define and develop the service interfaces for existing assets like enterprise resource
                 planning (ERP) and enterprise asset management (EAM) systems, while identifying the white
                 space requiring development of integration or transformation services.
              •   Deploy: install and configure the execution environment to meet service-level requirements nec-
                 essary for your business processes to flourish.
              •   Manage: monitor and adjust configurations for optimal performance and availability. Review
                 actual consumer/publisher interaction patterns as the introduction of the SOA often identi-
                 fies  new  opportunities  for  synergy  between  applications  and  improves  overall  application
                 effectiveness.

              The WebSphere suite of integration products provide high-performance process and data integra-
            tion between internal customer applications or external business partner applications. The core prod-
            ucts comprise:
