What is TOGAF?
The Open Group Architecture Framework is a framework – a detailed method and a set of supporting tools – for developing an enterprise architecture for use within that organisation
TOGAF is developed and maintained by members of The Open Group, working with the architecture forum
History of TOGAF
1994 the US Department of Defense gave their Technical Architecture Framework for Information Management (TAFIM) to TOGAF for development
1995 TOGAF version 1 was released
2009 TOGAF version 9 was released
What was new in TOGAF 9 Design objectives
Evolution not revolution
No change to the top level processes
Interoperability between TOGAF 8 and 9
Stronger links to business
Strategic Planning
Deployment decisions
Easier to use
A More formal meta-model
More guidelines and techniques
Improved structure

What is Enterprise Architecture?
Architecture of an Enterprise
A formal description of a system, or detailed plan of a system at component level, to guide its implementation OR The structure of components, their inter-relationships, and the guidelines governing their design and evolution over time
The highest level ( typically) of description of an organisation and typically covers all missions and functions. An enterprise will often span multiple organisations
“An effective enterprise architecture is critical to business survival and success and is the indispensable means to achieving competitive advantage through IT”
Why do we need Enterprise Architecture? ď ľ
Optimise the often fragmented legacy of processes (both manual and automated) into an integrated environment that is responsive to change and supportive of the delivery of the business strategy
ď ľ
Good enterprise architecture helps achieve the right balance between IT efficiency and business innovation.
Benefits of Enterprise Architecture
Create a more efficient IT Operations
Lower software development, support and maintenance costs
Increased portability of applications
Improved interoperability and easier system and network management
Improved ability to address critical enterprise-wide issues like security
Easier upgrade and exchange of system components
Better return on existing investment, reduced risk for future investments
Reduced complexity in IT infrastructure
Maximum return on investment in existing IT infrastructure
Reduced risk overall in new investment, and the costs of IT ownership
Faster, simpler and cheaper procurement
Buying decisions are simpler, because the information governing procurement is readily available in a coherent plan
The procurement process is faster
What is an architecture framework
Foundational structure used to develop a broad range of different architectures.
Provides a method to help design a target state of the enterprise in terms of building blocks, and to show how the building blocks fit together
Set of tools and common vocabulary
List of recommended standards
Why use TOGAF as an architecture framework
300 Architecture forum members
Leading vendors and service providers
Neutral and Open
Plays an important role “de-mystify” and “de-risk” the architecture development process
Core Concepts of TOGAF Architecture Capability Architecture Development Method
The organisation structure, roles, responsibilities, skills and process required to practice Enterprise Architecture
Enterprise Continuum Architecture Continuum Solution Continuum
Deliverables Artifacts
Building Blocks
Architecture Repository Architecture Meta-model Reference Library
ADM provides a tested and repeatable process for delivering architecture s
Techniques and Tools
Is a view of the architecture repository that provides methods for classifying architectures and solution artifacts as they evolve
Standards Information Base Architecture Landscape
Stores different classes of architecture outputs at different levels of abstraction.
Types of architecture domains Enterprise Architecture Business Architecture
How the business is organised to met its objectives
IT Architecture
Information Systems or Applications Architecture Data Architecture Technology Architecture
How the information System support the objective of the business Structure of the data assets
How the technology fits together
Architecture Domains : Definitions
Architecture Domain: The architecture area being considered
Business architecture: The business strategy, governance, and key business processes information as well as the interaction between these concepts
Application architecture: A description of the major logical groups of capabilities that manage the data objects necessary to process the data and support the business
Data architecture: The structure of an organisation’s logical and physical data assets and data management resources
Technology architecture : The Logical software and hardware capabilities that are required to support deployment of business, data and application services, includes middleware, networks, communications etc.
