This document provides an introduction to enterprise architecture and the TOGAF framework. It defines key terms like enterprise, architecture, and enterprise architecture. It describes the purpose and benefits of enterprise architecture, including better information management, competitive advantage, and more strategic IT planning. The document introduces TOGAF as an open standard enterprise architecture framework developed by The Open Group consortium to help organizations design, implement, and govern enterprise architecture.

1. Introduc)on to
Enterprise Architecture & TOGAF
Module 1

2. Module Objec)ves
• To provide an overview of Enterprise Architecture
and TOGAF, an Open Group Standard.
• Enterprise Architecture
• TOGAF – The Enterprise Architecture Framework
• The Open Group
• Summary

3. What is an Enterprise?
• A collec@on of organiza@ons that share a common
set of goals
• Large corpora@ons may include mul@ple enterprises
• “Extended Enterprise” may include partners,
suppliers and customers

4. What is an Architecture?
• The art or prac@ce of designing and construc@ng
systems with
• its components
• their rela@onships to each other and the
environment
• and the principles governing its design and
evolu@on

5. What is Enterprise Architecture?
• An enterprise architecture (EA) is a conceptual
blueprint that defines the structure and opera@on of
an organiza@on.
• The intent of an EA is to determine how an
organiza@on can most effec@vely achieve its current
and future objec@ves.

7. What is Enterprise Architecture?

8. EA in a Nutshell…
AS IS / CURRENT STATE TO BE / FUTURE STATE

9. Why Enterprise Architecture?
• Effec@ve management and exploita@on of
informa@on through IT is key to business success
• Good informa@on management = compe@@ve
advantage
• Current IT systems
• fragmented, duplicated
• poorly understood, not responsive to change
• tac@cal developments rather than a strategic plan

10. Why Enterprise Architecture?

11. Pressure to Develop EA
• Laws and regula@ons
• Clinger-Cohen Act, Sarbanes-Oxley
• More extended enterprises
• Audit requirements
• Greater publicity to failures
• More focus on IT

12. Business Benefits of EA
• A more efficient business opera@on
• A more efficient IT opera@on
• BeSer return on exis@ng investment (ROI)
• Reduced risk for future investment
• Faster, simpler and cheaper procurement

13. The Importance of Governance in EA
• An EA is only as good as the
decision making framework
that is established around it
• The Governance Framework
depends on
• clear authority structure
• the right par@cipants
• Who is responsible? Who is involved? Who is accountable?

14. Enterprise Governance
EA Governance
• Governance means establishing and enforcing how
people and solu@ons work together to achieve
organiza@onal objec@ves.

15. Enterprise Architects & Others

16. What is an Architecture Framework?
• A conceptual structure used to develop, implement
and sustain an enterprise architecture
• It should include
• a method for designing target state of the
enterprise using building blocks showing their
interac@ons
• a set of tools and a common vocabulary
• recommended standards and compliant tools to
implement the building blocks

17. The Value of a Framework
• Provides a prac@cal star@ng point for any project
• avoids the ini@al panic
• capture what others have found in real life
• contains a baseline set of resources for reuse

18. The Open Group Architecture Framework
• TOGAF is a framework - a detailed method and a set
of suppor@ng tools - for developing an enterprise
architecture
• TOGAF is developed and maintained by members of
The Open Group.

19. TOGAF Overview

20. TOGAF Architecture Domains
Business Architecture
(Business Processes, Organization, People)
Application
Architecture
(Services)
Data Architecture
(Data, Information)
Technology Architecture
(Hardware, Software, Network)

21. TOGAF Scope
• TOGAF emphasizes business goals as architecture
drivers, and provides a repository of best prac@ce,

22. The Open Group…
• is an interna@onal vendor and technology neutral
consor@um that organiza@ons rely on to lead the
development of IT standards and cer@fica@ons
• provides guidance and open environment to enable
interoperability and vendor-neutrality
• membership is open to all enterprises, anywhere in
the world, since 1996

24. The Open Group’s Vision
• “access to integrated informa@on to support
business process improvements”
• desired state for an enterprise’s infrastructure to
support business

25. The Open Group Ac)vi)es
• Governing Board work groups
• Open CA (Cer@fied Architect) Work Group
• Open CITS (Cer@fied IT Specialist) Work Group,
UNIX Work Group
• Member Forums
• Architecture, Archimate
• Enterprise Management, Trusted Technology
• Work Groups
• Business Architecture
• Cloud Compu@ng

26. The Open Group Architecture Forum - Mission
• The mission of The Open Group Architecture Forum
is to advance the vision of Boundaryless Informa@on
Flow, for and between enterprises
• Through a set of programs that focus on all
architectural aspects, including
• providing leadership to EA community
• valida@ng, publishing best prac@ces for EA
• ini@a@ng and managing programs to support
these ac@vi@es

27. Summary
• The Open Group Architecture Framework
• An effec@ve, industry standard framework and
method for enterprise architecture
• Complementary to, not compe@ng with, other
enterprise frameworks
• A repository of best prac@ce
• Vendor, tool and technology neutral
• A framework and method for achieving the
“Boundaryless Informa@on Flow” vision
