2. Agenda • The Architecture Forum • TOGAF • background • components • Summary (C) The Open Group 2003

3. Target • An effective, open framework and method TOGAF “Enterprise Edition” TOGAF “Technical Edition” ADM TRM SIB BBIB Resource Base TOGAF • Knowledgeable and professional practitioners TOGAF Training Certification TOGAF Practitioner Certification TOGAF Prof. Svcs. Certification • Adequate “Commercial Off-The-Shelf” tools TOGAF Tool Support Certification Architecture Forum – Vision and Achievements (C) The Open Group 2003

4. TOGAF Origins • A customer initiative • A framework, not an architecture • A framework for developing architectures to meet different business needs • Not a “one-size-fits-all” architecture • Originally based on TAFIM (U.S. DoD)

5. TOGAF Development Proof of need Proof of concept Proof of application Relevance to practical architectures (building blocks) Enterprise Continuum (TOGAF in context) Business Scenarios (architecture requirements) Architecture views - IEEE 1471 Architecture Principles; Compliance Reviews Extension to Enterprise Architecture • 1994: Requirement • 1995: TOGAF Version 1 • 1996: TOGAF Version 2 • 1997: TOGAF Version 3 • 1998: TOGAF Version 4 • 1999: TOGAF Version 5 • 2000: TOGAF Version 6 • 2001: TOGAF Version 7 • 2002: TOGAF Version 8

6. TOGAF Scope • TOGAF covers the development of four related types of architecture: • Business architecture • Data or information architecture • Application architecture • Technology architecture TOGAF 8“Enterprise Edition” TOGAF 7 “Technical Edition” TOGAF 7 “Technical Edition” (C) The Open Group 2003

7. TOGAF Version 8 (“Enterprise Edition”) • An effective, industry standard framework and method for enterprise architecture. • Complementary to, not competing with, other enterprise frameworks • Use in conjunction with frameworks having defined deliverables more specific to particular sectors. • “Demystifies” architecture development • Emphasizes business goals as architecture drivers • A framework and method for achieving the “Boundaryless Information Flow” vision (C) The Open Group 2003

8. TOGAF Structure and Components • Architecture Development Method (ADM) • Reference Architectures • Foundation Architecture • Technical Reference Model • Standards Information Base • Boundaryless Information Flow Reference Model (TOGAF Version 8) • Enterprise Continuum (reference architecture “framework”) • Resource Base (C) The Open Group 2003

9. TOGAF ADM Overview • An open, industry consensus method for IT architecture • Developing an organization-specific architecture to address business needs • Architecture views to ensure that complex requirements are adequately addressed • Practical, experience based guidance • Adaptable to specific needs of a project (C) The Open Group 2003

10. Prelim: Framework and Principles AArchitecture Vision H ArchitectureChange Management BBusiness Architecture Requirements CInformation System Architectures G Implementation Governance F MigrationPlanning DTechnology Architecture EOpportunitiesand Solutions “Enterprise” ADM – Key Points • An iterative method • Each iteration = new decisions: • Enterprise coverage • Level of detail • Time horizon • Architecture asset re-use: • previous ADM iterations • other frameworks, system models, industry models,…) • Decisions based on: • Competence / resource availability • Value accruing to the enterprise. (C) The Open Group 2003

11. Qualities Infrastructure Applications Business Applications Application Programming Interface System & Network Management Software Engineering Security Transaction Processing Location & Directory User Interface International Operations Data Interchange Data Management Graphics & Image Operating System Services Network Services Communications Infrastructure Interface Communication Infrastructure Foundation Architecture: Technical Reference Model • Associated with detailed taxonomy of services • defines scope of each service category • Identifies system-wide capabilities or “qualities”; e.g.: • Security • Manageability (C) The Open Group 2003

12. Foundation Architecture: Standards Information Base (SIB) • A database of open industry standards • The complete set of Open Group endorsed standards • Content determined by Open Group consensus process • Structured according to TOGAF Technical Reference Model taxonomy • Available for public web access • http://www.db.opengroup.org/sib.htm • Gateway to many linked resources (C) The Open Group 2003

13. Boundaryless Information Flow Reference Model • A model of the major component categories for developing, managing, and operating an integrated information infrastructure. • A model of a set of applications that sit on top of an application platform. • An expanded subset of the TOGAF Technical Reference Model, using different orientation.
