    • Services in Business
      • Services we provide
        • To customers
        • To other stakeholders e.g. partners, suppliers, government
        • To other business units
      • Services we consume
        • From service providers
        • From other stakeholders
        • From other business units
      • Typically supported by services at other levels e.g. Process, Application, Information, Technical
    • Applications
      • No longer monolithic, isolated
      • Sometimes not ours
      • Sometimes distributed
      • Heterogeneous technologies
      • Need to think of as a
        • Bundle of functions
        • Exposed as services
        • Malleable, like Amoeba
      • Logical Applications vs Physical Components
        • Components can be part of more than one application
        • Components can be replaced without impacting overall service

    • Interfaces
        • Where things fit together
        • Plug and Play
        • Replace
          • Technology
          • Implementation
        • without impact
        • Require standards
        • Loose coupling
    • Planning vs Realisation
      • Requirements expressed at logical level
        • Independent of
          • Implementation
          • Technology
          • Detail
      • Realisation expressed at physical level
        • Technology dependent
      • Mapping essential between perspectives
    • Meta Model
      • Defines the necessary concepts, relationships and properties
      • Covers domains of business, process, application, information, technology
      • Distinguishes between logical and physical
      • Maps domains & layers
      • Maps to notation to represent / model
    • Meta Model Excerpt Logical Business Service Physical Application Service Logical Application Service Physical Business Service Physical Informa-tion Service Logical Informa-tion Service Logical Technical Service Physical Technical Service Decomposition Realisation
    • Content & Meta Model WSDL for web services Need equivalents for higher level service definitions..

    • X Reference
      • Must be able to trace the
        • Realisation of Services from Logical to Physical
        • Decomposition of Services to lower supporting layers
        • Composition of Services into
          • Processes
          • “ Applications”
          • System Software Products
        • Support of services for Products
      • Must be able to categorise by e.g.
        • Delivery mechanism (channel)‏
        • Technology / medium
        • Etc.
    • Enrichment

          • Risk, Cost, Quality
        • Computation and Analysis facilities built in add huge value
    • Notation
      • Must distinguish between
        • Domains
        • Logical and Physical
