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

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

TOGAF Scope q TOGAF covers the development of four related types of architecture: § § 1/1/2022 TOGAF 7 “Technical Edition” Business architecture Data or information architecture TOGAF 8 “Enterprise Edition” Application architecture Technology architecture TOGAF 7 “Technical Edition” 6 (C) The Open Group 2003

TOGAF Version 8 (“Enterprise Edition”) q q 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. q q q 1/1/2022 “Demystifies” architecture development Emphasizes business goals as architecture drivers A framework and method for achieving the “Boundaryless Information Flow” vision 7 (C) The Open Group 2003

TOGAF Structure and Components q q 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”) q 1/1/2022 Resource Base 8 (C) The Open Group 2003

TOGAF ADM Overview q q q 1/1/2022 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 9 (C) The Open Group 2003

“Enterprise” ADM – Key Points q q An iterative method Each iteration = new decisions: § § q Enterprise coverage Level of detail Time horizon Architecture asset re-use: § previous ADM iterations § other frameworks, system models, industry models, …) A H Implementation Governance Requirements F Migration Planning (C) The Open Group 2003 B Business Architecture C G Decisions based on: 10 Architecture Vision Architecture Change Management § Competence / resource availability § Value accruing to the enterprise. 1/1/2022 Prelim: Framework and Principles Information System Architectures D E Opportunities and Solutions Technology Architecture

Foundation Architecture: Technical Reference Model Qualities Infrastructure Applications q Business Application Programming Interface § Graphics & Image Data Management Data Interchange International Operations User Interface Location & Directory Transaction Processing System & Network Management Security Software Engineering Operating System Services Network Services Communications Infrastructure Interface Communication Infrastructure 1/1/2022 11 Associated with detailed taxonomy of services (C) The Open Group 2003 q defines scope of each service category Identifies system-wide capabilities or “qualities”; e. g. : § § Security Manageability

Foundation Architecture: Standards Information Base (SIB) q q 1/1/2022 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 12 (C) The Open Group 2003

Boundaryless Information Flow Reference Model q q q 1/1/2022 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. 13 (C) The Open Group 2003
