ArchiMate introduction
Wilbert Kraan
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
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
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)
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
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

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!

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
