2. Key Learning Points
 At the end of this lesson you should be able to
 Describe what an enterprise is
 Explain the purpose of an Enterprise Architecture
 Define further key terms and concepts related to
Enterprise Architecture
 Describe how the TOGAF Standard and the
ArchiMate modeling language are related

3. The Enterprise
 Enterprise
 Collection of organizations
 Common set of goals
 May include locally distant organizations
 Examples: Government agencies, corporation,
division, departments
 Extended enterprise
 Includes partners, suppliers and customers

4. Enterprise Architecture
 Standard definition (TOGAF, Archimate)
 Fundamental organization of a system
 Embodied in its components
 Relationship to each other
 Principles of design and evolution
 Variances
 Organizing logic for business processes and IT
Infrastructure
 Conceptual blueprint defining structure and operation
of an organization
 Process of translating business vision and strategy
into effective enterprise change

5. Key concepts and terms
 Stakeholders (Key roles with concerns)
 Internal vs. External
 Individuals, teams, organizations
 Examples: Regulatory bodies, Suppliers, Customers, Internal
departments, Management (CEO, CIO, CFO, etc.)
 Concern
 Crucially important to stakeholders
 Determine a system´s acceptability
 E.g.: Security Architect: authentication, authorization, audit,
assurance, etc.
 Viewpoint
 Focus on particular aspects
 Addresses a stakeholder´s particular concerns
 Facilitate communication

6. Why EA???
 More efficient business operation
 More efficient IT operation
 Better return on investment
 Reduced risk for future investment
 Procurement: faster, simpler and cheaper

8. ArchiMate version history
 Based on IEEE 1471 (architecture description)
 Developed from 2002-2004 (4M €) by Dutch
Government
 Ownership since 2008: The Open Group
 Archimate 1.0 – released in February 2009
 ArchiMate 2.0 – A major update January 2012
 Supports modeling throughout the TOGAF
Architecture Development Method
 ArchiMate 2.1 – December 2013
 A maintenance update addressing
 Feedback and comments raised on ArchiMate 2.0

9. ArchiMate Modelling language
 IEEE 1471 Architecture description = formal description
 Reasoning about structural and behavioral properties
 Of a system and its evolution
 Define building blocks of overall information system
 Provide a plan
 Manage IT investment in a way that meets requirements
 ArchiMate Specification
 Common graphical modelling language for EA
 Including transformation and migration planning
 Motivations and rationale
 Uniform representation for diagrams
 Integrated approach
 Different architecture domains
 Underlying relations and dependencies
