The TOGAF Approach to
Enterprise Architecture

8. Copyright © 2015 ITpreneurs. All rights reserved.
Enterprise Architecture (EA)
“Those properties of a thing and its
environment that are necessary and
sufficient for it to be fit for purpose for its
mission” (L. Fehskens)
“Managing the execution of the
corporate strategy” (J. Scott)
“Fundamental concepts or properties of
a system in its environment embodied in
its elements, relationships, and in the
principles of its design and evolution”
(ISO/IEC 42010)

9. Copyright © 2015 ITpreneurs. All rights reserved.
EA aligns strategy to operations, and
business demand to IT supply, ensuring
changes are in line with strategy and goals
Enterprise Architecture provides insight into
the current and desired state of the
organization, information systems and
technology
EA improves quality of individual solutions,
simplifies their development and
maintenance, and prolonging their life time
Why Enterprise Architecture?
Alignment
Insight
Quality

TOGAF
● Framework for Enterprise Architecture (EA)
● Originally developed by the US government
in the 80s, now owned by the Open Group
● De facto EA standard in the market
● A description of processes, techniques and
products for EA
● A generic framework that can be tailored to
the situation

11. Copyright © 2015 ITpreneurs. All rights reserved.
● The core of TOGAF
● A proven way of developing an
architecture
● Specifically designed to address
business requirements
● An iterative method
● A set of architecture views to ensure
that a complex set of requirements
are adequately addressed

Manifesto for Agile Software Development
We are uncovering better ways of developing
software by doing it and helping others do it.
Through this work we have come to value:
Individuals and interactions over processes and tools
Working software over comprehensive documentation
Customer collaboration over contract negotiation
Responding to change over following a plan
That is, while there is value in the items on
the right, we value the items on the left more.

Principles behind the agile manifesto
● Our highest priority is to satisfy the customer
through early and continuous delivery of
valuable software.
● Welcome changing requirements, even late in
development. Agile processes harness change for
the customer's competitive advantage.
● Deliver working software frequently, from a
couple of weeks to a couple of months, with a
preference to the shorter timescale.
● Business people and developers must work
together daily throughout the project.
● Build projects around motivated individuals. Give
them the environment and support they need, and
trust them to get the job done.
● The most efficient and effective method of
conveying information to and within a development
team is face-to-face conversation.
● Working software is the primary measure of
progress.
● Agile processes promote sustainable
development. The sponsors, developers, and
users should be able to maintain a constant
pace indefinitely.
● Continuous attention to technical excellence and
good design enhances agility.
● Simplicity--the art of maximizing the amount of
work not done--is essential.
● The best architectures, requirements, and designs
emerge from self-organizing teams.
● At regular intervals, the team reflects on how to
become more effective, then tunes and adjusts its
behavior accordingly.

Scaled Agile Framework

Agile is designed for
small teams
Dean Leffingwell
The boys from Rational
Unified Process are back.
Building on the profound
failure of RUP, they are
now pushing the Scaled
Agile Framework as a
simple, one-size fits all
approach to the agile
organization

We do not face,
analyse failures and
limitations of our
assertions, claims,

Role of Enterprise Architect in SAFe
source: http://scaledagileframework.com
- maintain holistic vision
- aligns business drivers with
technical decisions
- sets technology standards
- drive common infrastructure
- influences modeling, design
and coding practices
- facilitates reuse of emergent
solutions, knowledge & patterns
- synchronizes issues and NFRs
across solutions

Chief architect
- coordinates work on high-level
architectural issues that cut
across multiple systems
- reviews development of new
systems to make sure they
avoid common mistakes, and
that they are aligned with
architectural vision
- the feedback is always just
suggestions and input - the
decision for the final design of
the system still lies with the
squad building it

What does this mean for training?
There remains a role for Enterprise Architects
○ Need for training on Enterprise Architecture and TOGAF
Some Enterprise Architects will become part of Scrum teams
○ Need for training on Agile and Scrum
People need better understanding of how EA and Agile relate
○ Opportunity for new training and consulting

● Architecture principles are laws that cannot be deviated from
● Developing an EA takes a long time
● TOGAF is a waterfall approach
● EA prescribes things that should be left to the project
