  6. Case Study: Procure to Pay Process But … Tools & Technology Applied Correctly Can Pave the Way for Successful Business Innovation • Standards (including open source) for interoperability • Self-defined, loosely coupled interfaces • Tools to visualize and integrate existing assets • Model Driven Architecture (MDA) • Declarative specifications and languages • Architecture is the key to successful business innovation

  7. What is Business Driven Development?Development as a Business Process An integrated approach to software development that aligns line-of-business, development and operations teams to improve business performance • Align Technology and Business priorities • Improve efficiency and responsiveness • Address Governance and Compliance requirements Software development becomes a driver of competitive advantage

  8. The IBM Vision for Business Driven Development Business applications will be deployed, monitored and managed through the manipulation of multi-level models Componentization of businesses into services BusinessModeling Real-time visibility of business Flexibly transform business Strategy Manage Monitor Link KPI’s BusinessDomain Process Transform Measure PlatformIndependent IT Domain Realize Sense PlatformSpecific Rapid deployment of enterprise apps and resources Service Oriented Architecture Software Modeling Rich Middleware Platform Deploy Value: Accurately and reliably capture and translate business intent into IT solutions

  9. Three Key Concepts To Adapt for Business Driven Development Service Oriented ArchitectureFocus on Flexibility and Reuse • An approach for designing and implementing distributed systems that allows a tight correlation between the business model and the IT implementation Model Driven ArchitectureFocus on Efficiency and Quality • A style of enterprise application development and integration based on using automated tools to build system independent models and transform them into efficient implementations Business Innovation and OptimizationFocus on Responsiveness and Optimization • A monitoring and management approach that leverages integrated resources to achieve aligned, accountable, and action-oriented business operations

  10. Key Standards and Technologies Used in Business Driven Development SOA and Web Service Standards Semantic Standards Business Services: Service Offerings and Components e.g. Book Flight, Low Fare Search, Update PNR Data Evolving Industry Semantics (ACORD, FIXML, OTAXML, UCCNet, ebXML) Service Interaction Components (WSRP, JSR 168) Transactions (WS-Tx) Infrastructure Standards Management Security (WS-SEC) Service Orchestration (WS-BPEL) Service Discovery (WSIL, UDDI, RAS) Service Invocation & Messaging (WS-I, SOAP) Service Description (WSDL, RAS) XML (Infoset, Namespace, Schema) Network Protocol (HTTP, SMTP, Other)

  11. Model Business Level Modeling Service Oriented Modeling and Design Assemble Construction of Services Assembly of Services (new and existing) Choreography of Services Business Innovation & Optimization Services Facilitates better decision-making with real-time business information DevelopmentServices Interaction Services Process Services Information Services IT ServiceManagement Enables collaboration between people, processes & information Orchestrate and automate business processes Manages diverse data and content in a unified manner Facilitates communication between services ESB Integrated environment for design and creation of solution assets Manageand secure services, applications & resources Partner Services Business App Services Access Services Connect with trading partners Build on a robust, scaleable, and secure services environment Facilitates interactions with existing information and application assets Apps & Info Assets Optimizes throughput, availability and performance Business Driven DevelopmentKey Development Phases Infrastructure Services

  12. Design ( Models, Patterns, Templates, Policy ) Composition User Interaction Invocation Information BusinessComponents SOA Programming Model • Design • Focus on business design modeling, simplification, and role-based collaboration • Use of declarative policy to control execution behavior and relationships • Invocation • Loosely-coupled call-style and event-driven interconnection of services with built-in support for topology transparency, mediation, and brokering featuring standards-based interoperability • User Interaction • Dynamic support for people integration into the business design • Composition of Business-level Applications • Wired assembly of services to form business-level applications, workflows, and business orchestration • Information • Built-in access to service state, disconnected service-data exchange, information composition and transformation • Business Components • Composable and reusable services

  13. Design ( Models, Patterns, Templates, Policy ) Composition User Interaction Invocation Information BusinessComponents SOA Programming Model Supported by Key Standards • JavaServer Faces • Standard way to construct user interfaces for web applications, JSR 168 portlets, etc. • MVC based User Interaction Framework • Service Component Architecture (SCA) • Component services programming model which provides a consistent framework for assembling solutions • Jointly developed/endorsed by IBM, BEA, IONA, Oracle, SAP, and Sybase • Apache Open Source Incubator Project • http://incubator.apache.org/tuscany/ • Service Data Objects (SDO) • Uniform (technology independent) way to represent data • Provides Single abstraction (common API) across JDBC ResultSet, JCA Record, XML DOM, JAXB, Entity EJB, CMI (for MQ messages), and so on • Co-developed by IBM and BEA • Business Process Execution Language (WS-BPEL) • Standard way to choreograph business processes • Standardization through OASIS

  14. Asset Consumption Asset Management Asset Production RAS Repository Service Asset Analysis Runtime Registry Development Time Repository Asset Certification Development-time Service Lifecycle • At development time services are: • Identified, Produced, Consumed, and Managed submit IDE IDE search modify/refine apply/ customize promote certify Asset Identification

Portfolio/Project Management Requirements Management IT Executive Architect Analyst Integration Developer Developer Business Driven Development Scenario Business and Construction Focused Tools IT Focused Tools Business Focused Tools SoftwareArchitecture Business Modeling BusinessPerformance Monitoring Design andAssemble Message Mediations Process Orchestration Middleware Platform Process Server Portal Server Enterprise Service Bus Enterprise Application Server

  18. Requirements Explorer for viewing requirements Create requirements and documents View requirements traceability from the perspective of either “trace-to” or “trace-from” Requirements Management • Create Business Vision Documents • Create Business Use Case Specifications • Define/Document Business Rule, Business Goal Requirements • Define detailed system requirements (use cases and supplementary requirements) • Trace enterprise requirements to business processes and service implementations Customer Benefit: • Document and capture business requirements • Capture traceability relationships between elements in the application

  19. Business Process Modeling and Analysis Analyst • Business analyst analyzes, designs, and simulates business process • Model from a Business perspective • As is and to be modeling • Business service identification • Specification of business KPI’s • e.g. Average time to open an account should be <18 hours • 80% or more of the total account opening requests should be approved • Business-level simulation • Used to optimize business process by understanding Process Duration, Costing, ROI, etc. Customer Benefit: • Business-level tools for modeling and simulation • Describe business-level services in context of business improvement

  20. Process Service Oriented Analysis, Modeling, and Design Architect • Business Process Model can be transformed and visualized as a UML model • Create the design model from the business process model • Understand the business intent • IT service identification • Create design model for new services (top-down) • Identify existing components for reuse (bottom-up) • Meet in the middle (most common) • UML Profile for Software Services aids in designing software services • Artifacts in Design Models can betransformed into service implementations Customer Benefit: • Architecture and design for service implementations • Automate application of design patterns • Build transformations from analysis and design to implementation

  21. Business Process Choreography & Mediation Integration Developer • Business Process Choreography is linking services together to formdeployable business processes: • Deployable process model based on WS-BPEL • Both Flow and Event based Business Process can be modeled • BPEL Editor (Flow based) • Business State Machine Editor (Event based) • Choreography includes automated and human based services • Mediation creation to transform/route service requests and responses Customer Benefit: • Simplified, standards-based business process development • Easily create mediations for routing/transforming requests between services

  22. User Interface Development Developer • Use automated tools to build portlets that expose business capabilities (services) • Portlet wizards to face J2EE applications with portal UI • eForms to extend user interactions beyond the the Enterprise and offline • Custom-built “situational” applications to fill in missing capabilties • Configure portlets into user interface compositions with role dependent access Customer Benefit: • Role appropriate user interface • Only relevant portions of applications or services are exposed • Rapid time to value

  23. Test Early, Test Often • Testing needs to occur across Business Driven Development: • Component • Service • Business Process • Composite Application • Functional • User Interface • Performance • Regression • System • Integrated set of test tools (that support SOA) and an integrated test environment is important

  24. SOA Governance for Business Driven DevelopmentA Governed Lifecycle End-to-end Development Process An approach and tools that effectively enable organizations to • Determine the business priorities • Execute development against those priorities • Measure their effectiveness Development Infrastructure In the context of a secure / governed infrastructure • Supports complex sourcing models (including geographically disperse) • Provides development compliance (audit trails and security that is transparent to the developers)

  25. Best Practices Skills & Experience SOA Governance & Management Method Domain Experts Roles, responsibilities, tasks, policies Customize process templates based on company requirements Process Engineer Process templates Project Planning Project Manager Detailed project plan Resource allocation SOA Governance for Business Driven Development • IBM SOA Governance & Management Method • Defines Roles, Responsibilities, Tasks, and • Policies for SOA governance based on best practices and real-world experience • Tools can be used to help automate the governance process • Method content can be customized content based customer requirements • Manage SOA projects • Build project plans and allocate resources

  26. Agenda • Business Driven Development for SOA • Software Development Platform for Business Driven Development and SOA • Summary • Mapping to the IBM Products
