Partners Telematica Instituut Enterprise Architecture & ArchiMate 2
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 3
Governance With Architecture Architecture is a strategic tool not just high-level design Architecture goes beyond ICT: enterprise architecture Stability & flexibility Seem to be contradictory, but a good architecture facilitates change! Communication with stakeholders architects, managers, customers, engineers, Analysis impact-of-change cost & performance Role of Enterprise Architecture Mission Vision Strategy as is Goals to be enterprise architecture domain/aspect architectures Actions culture leadership people products processes Operations people IT 4
Enterprise Architecture: Describing Coherence Information architecture? Product architecture Process architecture?? Application architecture? Technical architecture? Better Support for the Enterprise Architect Increasing need for precise documentation on the enterprise architecture level Integrating various models in many languages (UML, IDEF, BPMN, ARIS,...) Communicating about architecture with others Tool interoperability Needed: well-founded and practical standard for enterprise architecture modeling 5
ArchiMate Focus Visualization Analysis Integration What Has ArchiMate Delivered? A vision on enterprise architecture Focus on the relations between business and IT A language for describing architectures models give precision and make tool support possible Techniques for visualisation and analysis, aimed at various stakeholders A basis and vision for tools Visio stencils Long term goal: vendor-independent standard for architecture description 6
Integrated Modelling Integration An architecture might encompass for example: products organisation business processes applications systems This requires concepts for domains and relations, linked with existing techniques 7

Communicating Architectures Views & Viewpoints A viewpoint describes the set of concerns of one or more stakeholders. It defines how to build a view, e.g. by means of a template. A view is a representation of a system from a viewpoint. A view is what you see, looking from the perspective of the stakeholder and his/her concerns. 20
Viewpoints Classification product manager, CIO, CEO architect, software developer, business process designer Designing Deciding Informing customer, employee, others Details Coherence Overview Viewpoints for Designing Basic design viewpoints Organisation Business function Business process Information structure Application structure Application behaviour Infrastructure Resemble diagrams of e.g. UML Actor coordination Product Service realisation Business process coordination Application usage Application coordination Implementation & deployment 21
Application Behaviour Policy creation Home & Away Policy administration Policy creation Calculate risk Calculate premium Create policy Store policy Insurance request Insurance policy Customer file Viewpoints for Deciding Give a high-level overview for e.g. business managers Can be used to identify problems or possible improvements Example: Landscape map 2-D representation Possibly interactive 22

ArchiMate Adoption ArchiMate and TOGAF TOGAF: The Open Group Architecture Framework Provides methodical support for architects Architecture Development Method (ADM) gives you a process ArchiMate and TOGAF nicely complement each other: ArchiMate provides no architecture process TOGAF provides no architecture modelling technique E.g. Atos Origin NL use ArchiMate and TOGAF together 25
ArchiMate and Zachman What? How? Where? Who? When? Why? Planner Owner Designer Builder Subcontractor Information Business Behaviour Application Technology Structure Attributes Natural language Scope (contextual) Enterprise model (conceptual) System model (logical) Technology model (physical) Detailed representations Data Function Network People (out of context) Time Motivation ArchiMate and UML ArchiMate connects architectural domains It has a broader scope, but less detail than UML It acknowledges the need for specialized languages for different architectural domains, such as UML, BPMN and others Transformations to more detailed, specialized models Several ArchiMate concepts derived from UML (esp. for application and infrastructure) First version of a UML profile for ArchiMate available 26
ArchiMate and Model-Driven Architecture Computation Independent Model (CIM) Business model Domain model Business requirements Platform Independent Model (PIM) e.g. BPMN Model independent of workflow engine, or UML model independent of computing platform mapping mapping mapping mapping ArchiMate may help bridge the gap between CIM and PIM ArchiMate Platform Specific Model (PSM) e.g. UML model for a J2EE platform Results in Practice Applications at over 30 organizations e.g. Dutch Tax Administration and many other companies and government institutes Tools BiZZdesign, Troux Metis (certified) IDS Scheer, Adaptive, Telelogic (implementing) MEGA, Casewise, ASG, IBM (interested) Education Used by several Dutch universities and other educational institutes Rapidly growing international attention 27
