8. Boundaryless Information Flow • Enterprise IT should make information available • Where it is needed • When it is needed • To support the business operation of the boundaryless organization (C) The Open Group 2006

9. Target ADM TRM SIB BBIB Business Requirements Achieving Boundaryless Information Flow • Boundaryless information flow is implemented through enterprise IT architecture • It needs open standards to enable • Interchangeable and interoperable products • Interworking between enterprises (C) The Open Group 2006

10. Service Oriented Architecture • SOA is an architectural style • That re-structures applications as loosely-coupled, modular services • To deliver Boundaryless Information Flow (C) The Open Group 2006

13. The SOA Working Group • The mission of The Open Group SOA Working Group is to develop and foster common understanding of Service-Oriented Architecture in order to facilitate alignment between the business and information technology communities. • It does this by conducting a work program which will produce definitions, analyses, recommendations, reference models, and standards to assist business and information technology professionals within and outside of the Open Group to understand and adopt SOA. (C) The Open Group 2006

14. SOA WG Membership • Open to all Open Group Supplier and Customer Council members (platinum members, forum buyout members, and silver members) • 149 participants from 50 companies (C) The Open Group 2006

15. Initial Work Program • Formed in October 2005 • Three initial deliverables: • Definition of SOA • SOA Case Studies • Value that The Open Group can Add (C) The Open Group 2006

16. Initial Work Program - Status • Formed in October 2005 • Three initial deliverables: • Definition of SOA - Completed • SOA Case Studies - Ongoing • Value that The Open Group can Add - Completed (C) The Open Group 2006

17. How the Work Program Develops • Any Working Group member can propose a project • A proposed project must • Be within the Working Group’s scope • Be achievable with Working Group resources • Project proposals are approved by vote of the Working Group • Several project proposals have been approved and others are being developed, based on “Value” team recommendations (C) The Open Group 2006

18. Completed Projects • Definition of SOA • Value that The Open Group Can Add (C) The Open Group 2006

19. Definition of SOA An architectural style that supports service orientation • Service orientationA way of thinking in terms of services and service based development and the outcomes that services bring • ServiceA logical representation of a repeatable business activity that has a specified outcome (e.g., check customer credit; provide weather data, consolidate drilling reports), is self-contained and may be composed of other Services. It is a black box to consumers of the Service • Architectural StyleThe combination of distinctive features in which EnterpriseArchitecture is done, or expressed • The SOA Architectural style’s distinctive features: • Based on the design of the services comprising an enterprise’s (or inter-enterprise) business processes. Services mirror real-world business activity • Service representation utilizes business descriptions. Service representation requires providing its context (including business process, goal, rule, policy, service interface and service component) and service orchestration to implement service • Has unique requirements on infrastructure. Implementations are recommended to use open standards, realize interoperability and location transparency. • Implementations are environment specific, they are constrained or enabled by context and must be described within their context. • Requires strong governance of service representation and implementation • Requires a “Litmus Test", which determined a “good services” (C) The Open Group 2006

20. Value that The Open Group can Add • The main goal of the subgroup was to establish a set of areas which the Open Group could benefit the industry in the context of SOA. • There were 10 recommendations selected. • Definition of SOA (existing project) • SOA Case Studies (existing project) • SOA Maturity Model • SOA Reference Model • SOA Relation to EA (TOGAF) • Business-Driven SOA • Legacy Evolution to SOA • SOA Governance • Ontologies for SOA • SOA Key Performance Indicators (C) The Open Group 2006

21. Current Work Program • SOA Case Studies • Ontologies for SOA • SOA Governance • SOA/TOGAF Practical Guide (C) The Open Group 2006

22. SOA Case Studies See the Case Studies web page at www.opengroup.org/projects/soa-case-studies (C) The Open Group 2006

23. Ontologies for SOA • Objectives: • Improve Understanding • Basis for Model-Driven Implementation • Current State • Draft base ontology developed • Refined following workshop in Lisbon • To be presented to OMG joint SOA ABSIG, Ontology PSIG and Healthcare DTF at 13:00 on December 5 (C) The Open Group 2006

24. SOA Governance • Governance widely recognized as crucial for SOA • Project team currently • Establishing scope • Reviewing inputs – members and SOA Alliance • Will meet face-to-face in San Diego in January to start substantive drafting (C) The Open Group 2006

25. SOA/TOGAF Practical Guide • Relation of SOA to EA/TOGAF perceived as highest value the WG can add for SOA • Joint project of SOA WG and Architecture Forum • Working through steps of TOGAF Architecture Development Method to evaluate impact of SOA (C) The Open Group 2006

26. New Project Proposals • SOA Maturity Model • SOA Reference Architecture • Business-Driven SOA • SOA and Security (C) The Open Group 2006

27. In Conclusion • SOA is important to The Open Group because • The Open Group exists to drive the creation of boundaryless information flow through enterprise architecture • SOA is the style of enterprise architecture that enables boundaryless information flow • The Open Group is working on • SOA Case Studies • Ontologies for SOA • SOA Governance • SOA/TOGAF Practical Guide • With maturity models and reference architecture coming soon • Shared understanding is the best basis for collaboration (C) The Open Group 2006
