  1. ArchiMate introductionWilbert Kraan

  2. Overview ArchiMate background A little aside about Enterprise Architecture ArchiMate motivation- what it's meant to do ArchiMate application- what it's used for How ArchiMate works Tools Experiences

  3. Background Designed by a Dutch IT research group called Novay (formerly the Telematica Instituut) Currently used by many different organisations, including practically all of Dutch HE, and 30 + institutions in UK HE Now an Open Group standard; i.e. vendor independent

  4. A little aside on Enterprise Architecture Architecture the thing: “The fundamental organization of a system embodied in its components, their relationships to each other and to the environment, and the principles guiding its design and evolution.” (IEEE 1471) Enterprise architecture the approach: “Continuous alignment of an enterprise’s assets and capabilities with its mission and strategy.” (Fehskens, Open Group) “a coherent whole of principles, methods, and models that are used in the design and realisation of an enterprise's organisational structure, business processes, information systems and infrastructure” (Lankhorst, Novay)

  5. Motivation behind ArchiMate Enterprise Architecture modelling language i.e. It models: The organisation's structure Business processes Information systems Infrastructure Resembles UML, but simpler and with a lot of added enterprise architecture specific meaning Complements BPMN and UML, doesn't replace them Very good at modelling high level business entities and processes, doesn't aim to model process itself in detail

  6. Application ArchiMate aims to ease communication between as many different groups of people as possible (does not necessarily capture everything) Unified way of modelling EA Offers a good drill down approach – describing, analysing and visualising relations A lot of experience with ArchiMate has resulted in accepted, organisation-wide baseline models

  7. How does Archimate work? Information (static) Behaviour Structure (dynamic) Business Layer Application Layer Infrastructure Layer

  11. Insurance example: business layer

  12. Insurance example: business & application layer

  13. Insurance example: application & infrastructure layer

  15. Summing up: • Divided into sub layers based on requirements • All three layers are interdependent and support each other • Views: you only ever show a particular audience the part that they are interested in, in the way that makes sense to them

  16. Tools that support Archimate BiZZdesign Architect IDS Sheer ARIS Troux metis Avolution Abacus Sparxsystems Enterprise Architect Templates for Microsoft Visio and Omnigroup Omnigraffle Some people have used generic UML tools Archi!

  17. Some experiences from the JISC Enterprise Architecture projects Made users think in terms of business side rather than the application/technical side. Articulates the link between people, process, information and systems. Enhances the communication between different stakeholders Articulates the dataflow between systems and services that can be depicted in a presentable and understandable manner Makes analysts consider the audience before drawing activity diagrams
