  4. The interoperability challenge

  5. Is Business and IT divided or united by SOA? Do we have a shared understanding of business problems? Do we have a shared understanding of business opportunities? Do we collaborate to find solutions and act in unison to deliver?

  6. The interoperability chasm Entrenched IT Business Fear Projects Cost Products Value Organisation Standards “S” and “A”

  7. Who is the Babelfish? Too often Business and IT speak different languages Both sides continually argue that the other is “wrong” and they are “right” IT estates rarely look like the business Business rarely looks to the long term impacts of IT

  10. The three tenets of interoperability

  11. The three tenets of interoperability Method Delivery Organisation

  12. Method

  13. Our take on the SOA hype • SOA is not WS • SOA is not about BPEL • SOA is not about ESB • SOA is not about Technology • Not driven by the “How” HOW Service-oriented Architecture works because it represents a real-world “what we do”.

  14. Visibility Execution Context Service Description Service Real World Effect Interaction Contract & Policy Use the SOA Reference Model • Not vendor driven • Applies to business as well as IT • Defines what “good” looks like • Doesn't tell you “how” to do it A service is a mechanism to enable access to a set of one or more capabilities provided by one entity – the service provider – for use by others.

  15. Engage the business to determine the what, who and why • What: Defining the scope of services, this is about determining what the services actually are. • Who:Who are the external actors that drive the services or with which the services interact. • Why: Identifying why one service talks to another, and why external actors interact with the services • How: The detail about the processes that co-ordinate the services and also the detail on how a service itself will be implemented.

  16. Structure matters • Clearly defined structure • Defined areas of shared ownership • Driven by how the company works • “Do it once, well” • Aligned to the business goals • Driven by how the business wants to react • Think about Process second • NOT THE SAME AS ORG CHARTS • Millions of “Services” • Disjoint from how the company works • Lack of clear ownership • Duplication • Missed opportunities • Unclear strategy • Driven by techies using Web Services

  17. Rules for establishing an Enterprise SOA Work with the business to understand the key business services and their drivers Create the Enterprise SOA first then aim to deliver it tactically Ensure that tactical projects leave the company better off Deliver the Business Services Refine the Enterprise SOA Penalise the projects that make it worse

  18. Delivery

  19. A business-driven SOA drives the delivery approach • Sourcing Strategy • Delivery Model • Business Transformation • Delivery Transformation

  20. Delivering SOA Service Project Service Project Service Project Sign Off Service Project Service Project Service Project Service Project Service Project Context Update Business IT Architectural Governance Business SOA Programme Programme SOA

  21. Drive down from the top • Projects and enterprises should define their Service Architecture FIRST • Requirements and process need to be in the context of that architecture • Architecture needs to be defined so all stakeholders understand • Needs to be an collaborative exercise • Once you have the service, THEN think about process

  22. Organisation

  23. Can Enterprise Architecture build the bridge? Business IT Enterprise Architecture Interface Context Strategy Common Language Governance Tools Techniques

  24. Governance of a new IT Asset Business services are a new IT asset that require a new governance model: Not predicated on ownership Some form of centralisation Funding and resource planning Change management Standards - e.g. for business semantics and processes

  25. Organisation for SOA EA BU BU BU BU IT (AD) IT (AD) IT (AD) IT (AD) Funding and Governance Central IT (AD, Governance, SOI)

  26. Summary

  27. Summary To deliver the true value of SOA and become a service-oriented enterprise, we must recognise the importance of interoperability by: Investing in an enterprise SOA developed by both the Business and IT Ensuring delivery processes accommodate SOA approach Structuring the organisation to ensure successful delivery and ongoing management of assets
