Modelling with ArchiMate Marc Lankhorst
Principal Researcher Enterprise Architecture
Utrecht University, January 11, 2010
Overview
• Introduction
• Enterprise architecture
• The ArchiMate modelling language
• Integration of business, applications, and technology
• Role of service orientation
• Example: ArchiSurance, merger of an insurance company
• Relation with other developments
• UML, BPMN
• Zachman Framework
• TOGAF
Novay
• Independent, non-profit research institute
• Founded & funded by companies, the Dutch government,
and universities
• To create impact with ICT innovation
• In projects together with industry and academia
Enterprise Architecture
Context
• Business and ICT become closer
• Ever higher demands on ICT: complexity, flexibility
• Many changes, rapid time-to-market required
• Management & control difficult
• Architecture as a tool
• for communication
• for governance
• for innovation
Architecture IEEE Std 1471:
Architecture = structure(s) of a
system in terms of
• components,
• their externally visible properties,
• their relations,
• and the underlying principles
“Structure with a vision”

Better Support for the Enterprise
Architect
• Increasing need for precise documentation on the
enterprise architecture level
• Integrating various aspect models in many languages (UML,
IDEF, BPMN, ARIS, ...)
• Communicating about architecture with others
• Get away from the “fuzzy pictures” image
• Analysis of architectures before their implementation
• Needed: well-founded, practical, and vendor-independent
standard for enterprise architecture modelling
The ArchiMate Research Project
• 2½ years, July 2002 - December 2004
• approx. 35 man-years, 4 million euro
• Consortium of companies and knowledge institutes
• Directed by Novay (then still Telematica Instituut)

ArchiMate Scope
Main Benefits of ArchiMate
• Lean and mean language:
• just enough concepts, not bloated to include everything
possible
• Well-founded concepts & models give precision
• clear communication about architectures
• get away from the ‘fuzzy pictures’ image
• Links to existing approaches
• UML, BPMN, TOGAF
• International vendor-independent standard
• The Open Group
• Tool support
• several tools available
Service Orientation
Design Paradigms
Increased focus on the ‘outside’:
• Structured programming
• Object orientation
• Component-based development
• Service-oriented architecture (SOA)
• (Event-driven architecture?)
Service Orientation
Service
• Unit of externally available functionality
• Offered via clear interfaces
• Relevant for the environment
Web services as a prominent technological example
Service-Oriented Architecture
Is
• A way of thinking
• A bridge between business and IT
Is not
• Web services
• Asynchronous communication
• A software artefact (an ESB)
Services are Central to ArchiMate

Integrated Modelling
Integration
An architecture might encompass for example:
• products & services
• organisation
• processes
• information
• applications
• systems
• networks
This requires concepts for domains and relations,
linked with existing techniques

Similar concepts at each layer make the language
easier to learn and more consistent in use
(cf. Fred Brooks’ “conceptual integrity”)
Notation
• Most concepts have two notations:
• Icon
• Box with icon
• Sharp corners = structure
• Rounded corners = behaviour
• Notation resembles UML and BPMN
• to stay close to what architects already know
• Relations (arrows etc.) are also mostly taken from existing
languages, with a few exceptions

ArchiMate and UML/BPMN/…
• ArchiMate connects architectural domains
• Broader scope, but less detail than e.g. UML (software),
BPMN (processes)
• No replacement for these, but an ‘umbrella’ on top
• Several ArchiMate concepts derived from BPMN (esp.
business processes) and UML (esp. for application and
infrastructure)
• Easy to link to e.g. UML descriptions of detailed design or
BPMN process models

ArchiMate and The Open Group
ArchiMate and The Open Group
• ArchiMate now under the aegis of The Open Group
• Official ArchiMate 1.0 standard
• Original goal, a vendor-independent standard for
enterprise architecture modelling, is now a reality!
• ArchiMate Forum within The Open Group
• responsible for standardisation, further development of the
language, PR, etc.
ArchiMate and TOGAF
• TOGAF: The Open Group Architecture Framework
• Architecture Development Method (ADM) provides a way of
working
• Methodical support, but no description technique
• ArchiMate:
• a description language
• but no prescribed way of working
• A perfect match!
• People: ITAC
• Delivery method: TOGAF
• Description language: ArchiMate

Tool Support for ArchiMate
• Toolvendors:
• BiZZdesign: Architect
• IDS Scheer: ARIS ArchiMate Modeler
• Casewise: Corporate Modeler
• Telelogic (IBM): System Architect
• Troux: Metis
• (Agilense: EA Web Modeler)
• (Avolution: Abacus)
• (Promis: EVA Netmodeler)
• Microsoft Visio, Omnigraffle templates
• downloadable from www.archimate.org
• suitable for a first try, but no substitute for a ‘real’ tool
• Open source
• Bolton University: http://archi.cetis.ac.uk/ (work in progress)
