Foundations of enterprise architecture management and archi mate
- 1. FOUNDATIONS OF ENTERPRISE ARCHITECTURE MANAGEMENT AND ARCHIMATE Archimate Training June 2014
- 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
- 7. Why EA reloaded (strategy execution) Missio n Vision Strategy Goals Actions Operations As is To Be Enterprise Architecture Culture Processes Products People IT
- 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
