TOGAF
“A Definition”
TOGAF - “The Open Group Architecture Framework”
• TOGAF is a Framework - a Detailed Method and a Set of Supporting Tools - for
Accepting, Developing, Maintaining and Gaining Value from an Enterprise
Architecture.
– Set of Building Blocks and how they Fit Together
• a Framework not an Architecture
– Set of Tools
– Common Vocabulary
– Recommended Standards
– Compliant Products
• TOGAF Version 9.1 (2011)
• Open Standard Developed & Maintained by The Open Group
– The Open Group Architecture Forum
2

Boundaryless Information Flow™
3
The mission of The Open Group Architecture Forum is to
advance The Open Group vision of “Boundaryless
Information Flow”, for and between enterprises
• …achieved through Global Interoperability
• …in a Secure, Reliable and Timely manner
Interoperability
- The ability of two or more systems or components
to exchange information and use the information
that has been exchanged to do useful work.
Boundaryless does not mean there are no boundaries – it
means that boundaries are permeable to enable business.

Part I: Introduction
This part provides a high-level introduction
to the key concepts of enterprise
architecture and, in particular, to the
TOGAF approach. It contains the
definitions of terms used throughout
TOGAF and release notes detailing the
changes between this version and the
previous version of TOGAF.

TOGAF
“Types of Architectures”
• Business Architecture - The business strategy,
governance, organization, and key business
processes.
• Information Systems Architecture = Data
Architecture + Application (s) Architecture
– Data Architecture - The structure of an
organization’s logical and physical data assets and
data management resources.
– Application(s) Architecture - A blueprint for the
individual applications to be deployed, their
interactions, and their relationships to the core
business processes of the organization.
• Technology Architecture - The logical software
and hardware capabilities that are required to
support the deployment of business, data, and
application services. This includes IT
infrastructure, middleware, networks,
communications, processing, and standards.

Architecture Development Method
7
The TOGAF Architecture Development
Method (ADM) provides a tested and
repeatable process for developing
architectures.
• Preliminary Phase
• Phase A: Architecture Vision
• Phase B: Business Architecture
• Phase C: Information Systems
Architectures Phase D: Technology
Architecture
• Phase E: Opportunities & Solutions
• Phase F: Migration Planning
• Phase G: Implementation
Governance
• Phase H: Architecture Change
Management
• Requirements Management

Deliverables, Artifacts, and Building Blocks
8
Architects executing the ADM will produce a number of outputs as a result of
their efforts.
• Deliverable is a work product that is contractually specified and in turn
formally reviewed, agreed, and signed off by the Stakeholders.
• Artifact is an architectural work product that describes an aspect of the
architecture.
– catalogs (lists of things)
– matrices (relationships between things)
– diagrams (pictures of things).
• Building Block represents a
(potentially re-usable) component
of business, IT, or Architectural
Capability
– Architecture Building Blocks (ABBs)
– Solution Building Blocks (SBBs)
– Vendor, Product, Version

Enterprise Continuum
9
A Model for Structuring a Virtual Repository and Methods for Classifying
Architecture and Solution Artifacts
• Architecture Continuum
• Solutions Continuum

Architecture Repository
10
Supporting the Enterprise Continuum is the concept of an Architecture
Repository which can be used to store different classes of architectural output
at different levels of abstraction, created by the ADM. In this way, TOGAF
facilitates understanding and co-operation between stakeholders and
practitioners at different levels.
• Architecture Metamodel.
• Architecture Capability
• The Architecture Landscape
• The Standards Information Base (SIB)
• The Reference
• The Governance Log

Establishing and Maintaining an Enterprise
Architecture Capability

• Processes

TOGAF Content Overview
“Relationships”
• Central to TOGAF is the Architecture
Development Method (ADM)  TOGAF – Part II
• The Architecture Capability  TOGAF – Part VII
operates the ADM.
• The ADM is supported by a number of Guidelines
and Techniques  TOGAF – Part III
• This produces content to be stored in the
repository  TOGAF – Part IV
• This is classified according to the Enterprise
Continuum  TOGAF – Part V
• The repository is initially populated with the
TOGAF Reference Models  TOGAF – Part VI

“Architectural Artifacts”
• A "system" is a collection of components organized to accomplish a specific function
or set of functions.
• "Stakeholders" are people who have key roles in, or concerns about, the system
• "Concerns" are the key interests that are crucially important to the stakeholders in the
system
• A "view" is a representation of a whole system from the perspective of a related set of
concerns.
• A "viewpoint" defines the perspective from which a view is taken.
43
• Catalogs are lists of building blocks.
• Matrices show the relationships
between building blocks of specific
types.
• Diagrams present building blocks
plus their relationships and
interconnections in a graphical way
that supports effective stakeholder
communication.
