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
