4. What is Enterprise
“Any collection of organizations that has a common set of goals.” –TOGAF
An enterprise could be:
u a government agency
u a whole corporation
u a division of a corporation
u a single department
u or a chain of geographically distant organizations linked together by common
ownership.
Goals Process
Operating
Model
Structure Skills

5. What is Architecture?
u ISO/IEC 42010:2007 defines "architecture" as:
u "The fundamental organization of a system, embodied in its components, their
relationships to each other and the environment, and the principles governing its
design and evolution.”
u In TOGAF, "architecture" has two meanings depending upon the context:
u A formal description of a system, or a detailed plan of the system at component
level to guide its implementation
u The structure of components, their inter-relationships, and the principles and
guidelines governing their design and evolution over time
Mohamed Sami - https://melsatar.blog/

6. What is Enterprise Architecture
Enterprise architecture (EA) is the process of translating
business vision and strategy into effective enterprise
change by creating, communicating, and improving
the key principles and models that describe the
enterprise’s future state and enable its evolution.
A conceptual blueprint that defines the structure and
operation of an organization. The intent of an
enterprise architecture is to determine how an
organization can most effectively achieve it's current
and future objectives.

7. Enterprise Architecture?
What !!!!!

8. The Anatomy of a City
u The City architecture has a lot of layers
u What if we need to transform this city into a smarter
city?
u What if we need to upgrade the utility services?
u What if we need to have a big change in the city
sanitation?
Mohamed Sami - https://melsatar.blog/

9. Do we need the city
blueprint?
Mohamed Sami - https://melsatar.blog/

10. Similarly!!!
do we need anatomy
to describe the human
body?
do we need the
schematics of a car?
do the builders need
the map of the
house?
do we need The
enterprise
architecture?
Why

12. What is the value?
Mohamed Sami - https://melsatar.blog/

13. Value of Enterprise Architecture
Efficient
business
operation
Efficient IT
operation
Reduced risk
for future
investment
Faster,
simpler, and
cheaper
procurement
Increase
Business
Continuity
and Agility
Better
optimization
of resources
and eliminate
duplication
Mohamed Sami - https://melsatar.blog/

14. What is the real problem?
Business and IT Alignment !!
Mohamed Sami - https://melsatar.blog/

15. How can we solve that?
u Using common vocabulary
u Visualizing the concerns from stakeholders perspectives
u Establishing the language that all can understand
Having a framework
Mohamed Sami - https://melsatar.blog/

16. We need clear steps to be
able to solve this puzzle
Mohamed Sami - https://melsatar.blog/

17. What is the architecture framework?
is a tool that can be used for developing a broad range of
different architectures.
u It should describe a method for designing an information system in
terms of a set of building blocks, and for showing how the building
blocks fit together.
u It should contain a set of tools and provide a common vocabulary.
u It should also include a list of recommended standards and
compliant products that can be used to implement the building
blocks.
Mohamed Sami - https://melsatar.blog/

18. What is the value?
Mohamed Sami - https://melsatar.blog/

19. The framework value
Provides a practical starting point for an Architecture Project
u Avoids the initial panic when the scale of the task becomes
apparent
u Systematic – “Codified common sense”
u Captures what others have found to work in real life
u Contains a Baseline set of resources for reuse
Mohamed Sami - https://melsatar.blog/

20. What is TOGAF?
u TOGAF is an architecture framework – The Open Group
Architecture Framework. TOGAF is a tool for assisting in
the acceptance, production, use, and maintenance of
enterprise architectures. It is based on an iterative
process model supported by best practices and a re-
usable set of existing architectural assets.
Mohamed Sami - https://melsatar.blog/

21. Why TOGAF
A
comprehensive
general method
Widely adopted
in the market
Complementary
to, not
competing with,
other frameworks
Tailorable to
meet an
organization and
industry needs
Vendor, tool and
technology
neutral open
standard
Avoids re-
inventing the
wheel
Business IT
alignment
Based in best
practices
Possible to

23. TOGAF Structure
1. PART I - (Introduction) This part provides a high-level introduction to the key concepts of enterprise
architecture and in particular the TOGAF approach. It contains the definitions of terms used throughout
TOGAF and releases notes detailing the changes between this version and the previous version of TOGAF.
2. PART II - (Architecture Development Method) This part is the core of TOGAF. It describes the TOGAF
Architecture Development Method (ADM) - a step-by-step approach to developing an enterprise
architecture.
3. PART III - (ADM Guidelines and Techniques) This part contains a collection of guidelines and techniques
available for use in applying TOGAF and the TOGAF ADM.
4. PART IV - (Architecture Content Framework) This part describes the TOGAF content framework, including a
structured metamodel for architectural artifacts, the use of re-usable architecture building blocks, and an
overview of typical architecture deliverables.
5. PART V - (Enterprise Continuum & Tools) This part discusses appropriate taxonomies and tools to categorize
and store the outputs of architecture activity within an enterprise.
6. PART VI - (TOGAF Reference Models) This part provides a selection of architectural reference models, which
includes the TOGAF Foundation Architecture, and the Integrated Information Infrastructure Reference
Model (III-RM).
7. PART VII - (Architecture Capability Framework) This part discusses the organization, processes, skills, roles, and
responsibilities required to establish and operate an architecture function within an enterprise.

24. Architecture Development Method
The Architecture Development Method (ADM)
forms the core of TOGAF and is a method for
deriving organization-specific enterprise
architecture. It is the result of contributions from
many architecture practitioners.
Set of phases:
u Cycling around the ADM
u Iterative between phases
u Cycling around a single phase
Mohamed Sami - https://melsatar.blog/

25. ADM Guidelines and Techniques
u A set of guidelines and techniques to support the
application of the ADM
u The guidelines help to adapt the ADM to deal with
different scenarios, including different process styles
u The use of iteration
u Specific requirements (e.g. security).
u The techniques support specific tasks within the ADM
u Defining principles
u Business scenarios
u Gap analysis
u Migration planning
Mohamed Sami - https://melsatar.blog/

26. Architecture Content Framework
A detailed model of architectural
work products, including Deliverables,
Artifacts within deliverables, and the
Architecture Building Blocks (ABBs)
that deliverables represent.
u It drives for greater consistency in
the outputs of TOGAF
u It provides a comprehensive
checklist of architecture outputs
u It promotes better integration of
work products
u It provides a detailed open
standard for how architectures
should be described
u It includes a detailed metamodel

27. Deliverables, Artifacts and Building Blocks
Mohamed Sami - https://melsatar.blog/

28. Enterprise Continuum
u The Enterprise Continuum is a
view of the Architecture
Repository that provides
methods for classifying
architecture and solution
artifacts, both internal and
external to the Architecture
Repository, as they evolve from
generic architectures to
Organization-Specific
Architectures, and similarly
generic solutions to
organization-specific solutions
Mohamed Sami - https://melsatar.blog/

29. Architecture Repository
One part of the wider
Enterprise IT Repository,
which provides the
capability to link
architectural assets to
components of the Detailed
Design, Deployment, and
Service Management
Repositories
Mohamed Sami - https://melsatar.blog/

30. The Architecture Landscape
u Strategic Architectures show a long-term
summary view of the entire enterprise.
u Segment Architectures provide more
detailed operating models for areas
within an enterprise. (program or portfolio
level)
u Capability Architectures show in a more
detailed fashion how the enterprise can
support a particular (unit of capability).
Mohamed Sami - https://melsatar.blog/

31. Reference Model
Two Reference Models are provided
u The TOGAF Technical Reference Model (TRM)
u A Foundation Architecture
u A model and a taxonomy of generic platform services
u The Integrated Information Infrastructure Model (III-RM).
u A model for business applications and infrastructure applications
u Specifically aimed to support the vision of Boundaryless Information Flow™
