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 enterprises 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

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

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
