    Archimate Introduction Archimate Introduction Presentation Transcript

    • Archimate introductionWilbert Kraan
    • Overview ArchiMate background  A little aside about Enterprise Architecture ArchiMate motivation- what its meant to do ArchiMate application- what its used for How ArchiMate works Tools Experiences
    • Background Designed by a Dutch IT research group called Novay (formerly the Telematica Instituut) Currently used by a wide range of organisations, including Dutch tax office, insurance companies, construction multinationals, most of Dutch HE Used by all JISC Enterprise Architecture group members in some way An Open Group standard; i.e. vendor independent Version 2.0 released 2 months ago; aligned with the TOGAF
    • Quick recap 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 enterprises  organisational structure,  business processes,  information systems and  infrastructure” (Lankhorst, Novay)
    • Motivation behind ArchiMate Enterprise Architecture modelling language  i.e. It models:  The organisations structure  Motivations, principles and goals  Business processes  Information systems  Infrastructure Resembles Unified Modelling Language (UML) Complements Business Process Modelling Notation (BPMN) and UML, doesnt replace them Very good at modelling high level business entities and processes, doesnt aim to model process itself in detail
    • 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

    • 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 15
    • 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! 16
    • Some experiences from the JISCEnterprise Architecture pilots 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 17
