Wilbert Kraan introduces Archimate and Enterprise Architecture modelling. Presented at the first JISC Emerging Practices workshop (2012/03/29). http://emergingpractices.jiscinvolve.org/wp/doing-ea-workshop/

1. Archimate introduction
Wilbert 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 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

4. 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 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
 Motivations, principles and goals
 Business processes
 Information systems
 Infrastructure
 Resembles Unified Modelling Language (UML)
 Complements Business Process Modelling Notation
(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

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 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
