  3. 3. The Current State and Trend for SOA Practice n Current State – More emphasis on applications and systems, weak in business involvement regarding n Enterprise Planning: business model, service model, cost model, etc. n Enterprise Management and Operation: service portfolio, lifecycle and governance, etc. – Started making progress in infrastructure to support service orientation n Cloud computing (promoted by Federal CIO, facilitated by industries) n Service oriented infrastructure (or infrastructure as a service, in addition to cloud computing support) – Lack of clarity about where SOA applies and where it doesn’t n Future Directions – Apply the service oriented approach across the full enterprise IT planning and operation lifecycle – Make progress in SOA applicable areas (e.g. cloud computing currently), and better handle their natural dependencies – SOA is a means for achieving goals, not a goal by itself 2 SOEA and SOE, Yan Zhao, Ph.D; The 23rd Open Group Enterprise Architecture Practitioners Conference © 2009 The MITRE Corporation.

  4. 4. EA, SOA, and SOEA n EA is an established discipline that deals with architectures in enterprise scope. It’s a subject domain that is independent of approaches and methodologies for its development and presentation n SOA is an architecture style and approach that emphasizes well-defined, loosely coupled, and sharable services n EA provides SOA with an enterprise view; SOA brings new agility to EA by delivering tangible results, which helps EA get broader acceptance and increased usability n SOEA: EA modeling with service-oriented style and approach – SOEA uses SOA as a practical modeling approach for appropriate part of EA development. – SOEA bridges EA with solution architecture and implementation by layered service components across business, application, and technology. – SOEA links enterprise model with service model that enables a better implementation from business strategies to IT capabilities. 3 SOEA and SOE, Yan Zhao, Ph.D; The 23rd Open Group Enterprise Architecture Practitioners Conference © 2009 The MITRE Corporation.

  7. 7. Concept of Service Oriented Enterprise n Service Oriented Enterprise (SOE): is an enterprise that applies service orientation to its full scope business management and operations where appropriate. n The SOE Practice – takes guidance from SOEA – is enabled by SOA implementation in businesses, applications and systems – is facilitated by Service Oriented Infrastructure (SOI) 6 SOEA and SOE, Yan Zhao, Ph.D; The 23rd Open Group Enterprise Architecture Practitioners Conference © 2009 The MITRE Corporation.

  9. 9. Relationship of SOE with SOA n As architecture is a part of the planning phase for an enterprise, SOA (or SOEA) is a part of the planning phase for SOE n As an enterprise uses service oriented approaches across their enterprise IT planning and operation lifecycle, the emergence of an SOE will be the natural evolutionary step forward from SOA. n SOE provides organizational enablement, capabilities, and readiness in achieving the widely claimed benefits of SOA. It provides environment that enables planning and execution of shared services across organization boundaries n SOE ensures an end to end adoption of service orientation and effectiveness in execution. 8 SOEA and SOE, Yan Zhao, Ph.D; The 23rd Open Group Enterprise Architecture Practitioners Conference © 2009 The MITRE Corporation.

  11. 11. SOE in Practice Apply service orientation to n Business Management and Operation – Enterprise planning and architectures – Enterprise portfolio management – Enterprise lifecycle and governance – Enterprise programs and projects n Business Process Modeling and Management – Layered business processes to implement layered business services – Business process implementation by layered business and IT services n IT Enablement, Support, and Facilitation – Application and system implementation and operation – Data implementation and operation – IT infrastructure implementation and operation 10 SOEA and SOE, Yan Zhao, Ph.D; The 23rd Open Group Enterprise Architecture Practitioners Conference © 2009 The MITRE Corporation. All rights reserved
  12. 12. Enterprise Service Portfolio Management n Enterprise service portfolio management should be built into enterprise plan, and be synchronized with strategy and governance n The enterprise service portfolio should take input from enterprise architecture n Integrate business processes with business services in enterprise service portfolio (layered processes and services) n Evolve application portfolio management to service portfolio management with services being categorized and being described in layers n Manage service portfolio lifecycle: planned services, current services, obsolete services 11 SOEA and SOE, Yan Zhao, Ph.D; The 23rd Open Group Enterprise Architecture Practitioners Conference © 2009 The MITRE Corporation.

  13. 13. Enterprise Governance Governance: policy, rules, structure, process, measurement nTwo Governance Aspects: – Governance of performance: for process execution and sustainable performance – Governance of change: for determination and management of changes nTwo Governance Stages (for each governance aspect): – Governance definition (legislative): structure, process, standard, rules, policies, guidelines, etc. – Governance enforcement (judiciary): enforcement of execution, results, and consequences 12 SOEA and SOE, Yan Zhao, Ph.D; The 23rd Open Group Enterprise Architecture Practitioners Conference © 2009 The MITRE Corporation.

  15. 15. IT Infrastructure Support n Service Oriented Infrastructure – IT infrastructure as a commodity service – IT infrastructure as a line of business – IT infrastructure architecture as a segment architecture in EA n Cloud Computing – Further enhances service orientation for enterprise IT infrastructure services – It consists of: n Software as a service n Platform as a service n Infrastructure as a service – It needs enablement from Service Oriented Enterprise in order to identify and apply appropriate service model, cost model, and operation model across organization boundaries – It shares the common nature and benefits of service orientation – It is started as a technology solution, but the implication is far beyond technologies 14 SOEA and SOE, Yan Zhao, Ph.D; The 23rd Open Group Enterprise Architecture Practitioners Conference © 2009 The MITRE Corporation. All rights reserved
  16. 16. The Impact of Service Orientation to an Enterprise n Service Orientation introduces a paradigm shift for enterprise – Manage business functions into loosely coupled services to reduce complexities and lessen the impact of changes n Service Orientation introduces changes to traditional organization culture and management mechanisms – Loosely coupled service organizations break stove pipes and promote collaboration – Dynamic relationships between service providers and service consumers – Achieve long-term benefits instead of short-term ones n Service Orientation can optimize enterprise operational cost – Shared services – Dynamic business changes supported by flexible IT service implementation n Service Orientation can enhance enterprise lifecycle and governance by introducing service life cycle and governance – Enable better scoping for measurement and control 15 SOEA and SOE, Yan Zhao, Ph.D; The 23rd Open Group Enterprise Architecture Practitioners Conference © 2009 The MITRE Corporation.

  17. 17. The Impact of Service Orientation to an Enterprise - Establish and Assess Return On Investment (ROI) Determine the full spectrum of SOA Assess ROI iteratively and Benefits compositely ROI for business agility Objectives for each service ROI for asset reuse Cost for each service implementation ROI from reduced development and Direct and indirect returns from the integration cost service ROI for common infrastructure Additional ROI obtained from reuse ROI from maintenance cost ROI from risk mitigation inputs guidance Reference Matrix for ROI inputs guidance IT Strategic Planning Performance Measurement 16 © 2009 The MITRE Corporation.

  18. 18. Conclusion n Service Oriented Enterprise Architecture is a sub-set of Enterprise Architecture n Service Oriented Domain is a sub-set of a Service Oriented Enterprise n SOA should be used where it applies, to reduce hype and confusion n SOA is a means, not a goal, during an enterprise’s continuous evolution of business and IT towards increased efficiency and reduced cost n Cloud Computing is a continuation of service orientation efforts in enterprise n There are natural dependencies in enterprise business management and operations with respect to service sharing, which can not be solved by technologies (as mentioned in the slide: The Impact of Service Orientation to an Enterprise) 17 SOEA and SOE, Yan Zhao, Ph.D; The 23rd Open Group Enterprise Architecture Practitioners Conference © 2009 The MITRE Corporation.
