The Open Group Architecture Framework (TOGAF)

TOGAF is an enterprise architecture framework that provides a comprehensive approach for designing, planning, implementing, and governing an enterprise information architectures.

Overview

The Open Group Architecture Framework (TOGAF)
Description:
TOGAF is an enterprise architecture framework that provides a comprehensive approach for designing, planning, implementing, and governing an enterprise information architectures. TOGAF organizes architectures into four domain level views:
  • Business Architecture: defines business strategy, governance, organization, and key business processes;
  • Application Architecture: specifies individual application systems to be deployed;
  • Data Architecture: defines structure of an organization's logical and physical data assets and associated data management resources; and
  • Technology Architecture: specifies software infrastructure intended to support the deployment of core, mission-critical applications.
Framework Classification:
Model-Based Enterprise Architecture Framework/
Compatible with multiple Architecture Description Languages but architecturally aligned with ArchiMate

Views/Viewpoints

  • Terminology Compatibility: Compatible with ANSI/IEEE 1471-2000 Views.
  • Views Specified: Business Architecture, Application Architecture, Data Architecture, Technology Architecture
  • ADL Compatibility: ArchiMate, UML, ...

Usage:
  • Primary Users: Commercial IT, ...
  • Other Users: N/A
Estimated Number of Users: N/A
Size/Complexity:
  • Size = Medium (4 Views and ??? work products)
  • Complexity = Medium (substantial Viewpoint and work product variation and semantic overlap)
  • Semantic integrity mappings across Views and work products is moderately specified when using ArchiMate as your Architecture Description Language.
Variations:
  • N/A
Origin/Derivation:
The first version of TOGAF (TOGAF v. 1.0) released in 1995 was based on the Technical Architecture Framework for Information Management (TAFIM) specification developed by the US Department of Defense (DoD). DoD gave The Open Group explicit permission to create TOGAF by building on the TAFIM, and TOGAF has been continuously evolving since then. TOGAF v. 9.x is the latest version.
Framework Design Style:
Compliance/Conformance/
  • Design-by-Committee anti-pattern inherited from DoDAF TAFIM continues to be manifested in TOGAF, but TOGAF is significantly less complex than its DoDAF counterpart. TOGAF is relatively parsimonious in its design, but suffers from lack of precision and ambiguity ("voodoo semantics").

Specification Rigor/Style:
Level of Rigor: Informal
  • Views/Viewpoints: Informally specified via a combination of natural language, conceptual graphics, and examples.
  • Work Products: Informally specified via a combination of natural language and examples.
  • Semantic integrity rules: Inadequate and ambiguous.
  • Metamodel: TOGAF Content Metamodel is conceptual.
  • Formal lexicon: Sparse and poorly defined.
