3. Shared Frustrations
We can clearly see some major
problems with the structure and
behaviour of large enterprises
and public sector ecosystems.
We can also see why current
initiatives are likely to fail.
But the people in charge of
these systems don’t appreciate
the valuable contribution we
could make.
We are often unable to
get access to working at
“the right level”.
We are forced to work
on fragments of the
problem rather than
the whole.
who is WE?
4. Audience
1. Those who are blithely ignorant of the uncertainties.
2. Those who recognize the uncertainties but haven’t the
time to do anything about them; they’ve got to get on with
the job.
3. Those who are attempting to shed light on the design
process and on methods for realistically handling
these uncertainties.

Classical, NeoClassical(Alex
ander)
Baroque, Complexity, Hyb
rid (Gartner)
Post-Modern (VPEC-T)
Systems Dynamics

Soft Systems Methodology
(Checkland)
Quality and Process
(Deming, Seddon)
Cybernetics (Beer)
Organic (Bateson, Maturana)
Ethical (Vickers, Churchman)
… and many more
EA ST
“But that’s not what I call
systems thinking!”
“But that’s not what enterprise
architects really do!”
who is WE?
6. Four hypotheses
(perhaps not mutually exclusive)
That systems thinking provides some
theoretical underpinning for enterprise
architecture and/or systems architecture.
That systems thinking and enterprise
architecture are essentially doing the
same things
(modelling, abstraction, joined-up
thinking, big picture, enterprise-as-
system, etc etc)
That systems thinking is somehow
complementary to enterprise
architecture, and that there is some kind
of synergy available from putting together
concepts, techniques and practices from
the two disciplines.
That systems thinking and enterprise
architecture are rivals for our
affections, and their respective champions
are trying to show that one is more
conceptually coherent, more broadly
based, more solidly grounded, and even
perhaps more useful, than the other.
7. Three Questions
What do EA and ST
have in common?
What can EA and ST
learn from each other?
What opportunities are
there for practical
collaboration between
EA and ST?
Where EA and ST may be
any of the following.
A body of knowledge
A community of practitioners
A tool or instrument for
achieving some defined goals.
A professional service
A discourse (way of talking)
8. Debate Groundrules
To prefer concrete
examples to sweeping
generalizations.
To combine grounded
practical experience with
theoretical reflection.
To avoid disputes
between rival schools
and frameworks.
To recognize that there
are many competing
definitions and
interpretations.
To tolerate
ambiguity, uncertainty
and difference.
To learn from others
rather than imposing
one’s own viewpoint.
9. Are EA and ST the same thing?
We have a concept of “system”.
We consider the whole enterprise “as a
system”.
We consider human activity systems as
well as mechanical systems (such as
software).
We are good at abstraction and
generalization.
We are good at “big picture”, joined-up
thinking. BUT
A human icon
makes a system into
a human system!
10. What does “enterprise-as-a-system” mean?
Enterprise as an open
or closed system?
Enterprise as a human
activity or
sociotechnical system?
Enterprise as a
dynamic, complex
adaptive or viable
system?
What is an enterprise?
Are humans inside or
outside the system?
Which notion of
dynamic?
Which notion of
complexity?
11. Different Notions of System?
“System” is part of the
problem space.
We try to understand the
structure and behaviour
of complex systems.
We then intervene to
improve their structure
and behaviour.
“System” is part of the
solution space.
We explore why the
existing solutions aren’t
performing (AS-IS).
We create blueprints for
improved solutions (TO-
BE)
ST (sometimes) EA (sometimes)
12. Different Notions of System Thinking?
Systems thinking gives us
a model of what is going
on …
… from the viewpoint of
a neutral and all-seeing
observer.
Systems thinking helps us
to make sense of what is
going on …
… from the viewpoint of
an engaged participant.
First Order Cybernetics Second Order Cybernetics
And what about third-order cybernetics?
What things should we be
looking at? (“Ontology”)
How we can know about these
things? (“Epistemology”)
13. Why New Systems Don’t Work
(Possibly)
Passive adoption
(resistance)
Poor
implementation
System as
designed system
in use
Poor choice of
technology
(technology
fetish)
Errors of Execution Errors of Planning
Changing
requirements
Local global
Short-term
longer-term
User customer
14. Why Old Systems Don’t Work
(Possibly)
Complexity
Attempts to eliminate
complexity
Cybernetic Entropy
management controls
becoming less effective
over time
Changing requirements
Hidden agenda
POSIWID (Stafford Beer)
Enterprise Ferality
“an autocatalytic
phenomenon that is self-
perpetuating” (Steve Brewis)
15. Different Stance?
(tongue in cheek)
Urgent action is necessary to avoid
imminent danger ("The Imminent
Danger")
All reforms work together and reinforce
each other, rather than being competing
("The Synergy Illusion")
History Is on Our Side.
Purposive action to improve some
feature of the political, social, or
economic order may only serve to
exacerbate the condition one wishes to
remedy. ("perversity thesis").
Attempts at social transformation are
often unavailing, that they will simply
fail to "make a dent." ("futility thesis")
The cost of the proposed change or
reform is often too high, especially if it
endangers some previous, precious
accomplishment. ("jeopardy thesis")
EA as progressive, visionary? ST as realist, reactionary?
Based on: Albert Hirschman
16. Different Religion?
(tongue in cheek)
What is necessary is to call things by their
right names. A superior man considers it
necessary that the names he uses may be
spoken appropriately, and also that what he
speaks may be carried out appropriately.
What the superior man requires, is that in
his words there may be nothing incorrect.
A name can be named, (but) this is not the
(constant) naming.
EA follows Confucius
ST follows Laozi
If names be not
correct, language is
not in accordance with
the truth of things.
If language be not in
accordance with the
truth of things, affairs
cannot be carried on
to success.
When affairs cannot
be carried on to
success, proprieties
and harmony will not
flourish.
When proprieties and
harmony do not
flourish, punishments
will not be properly
awarded.
When punishments
are not properly
awarded, the people
do not know how to
move hand or foot.
17. Different Discussion?
(tongue in cheek)
The verbal play of opposites that gradually
builds up to a synthesis.
Competition between ideas - one idea
establishes primacy over the others.
Fetish of assertion (Bernard Williams)
The goal of a dialectic process is to merge
point and counterpoint (thesis and antithesis)
into a compromise or other state of
agreement via conflict and tension (synthesis).
Mutual exchange for its own sake.
An idea does not merely
answer, correct, silence, or extend an earlier
idea, but informs and is continually informed
by the earlier idea.
That world of talk that makes an open social
space, where discussion can take an
unforeseen direction.
Information-sharing is an exercise in
definition and precision, whereas
communication is as much about what is left
unsaid as said; communication mines the
realm of suggestion and connotation.
(Richard Sennett)
Dialectic? Dialogic?
Based on: Mikhail Bakhtin
18. Which Practice?
An individual or team customizes a
framework for a specific project or
organization.
The project or organization deviates from
the official framework in various ways.
Adding and subtracting activities
Simpler or more complicated pathways
Links to other frameworks
Use of available tools
A project may be retrospectively massaged
to comply with an official framework.
The participants may be more or less
aware of any deviations and their
consequences.
Official
• What the
book says
Emergent
• What the
community
does
Espoused
• What the
team thinks
it is doing
In-Use
• What the
team
actually
does
To what extent can the framework take
the credit for successful outcomes?
19. Five Anxieties
1. Hierarchical Nature of
Complexity
Escalation
Infinite Regression
(The Warning of the
Doorknob)
2. Inclusiveness of
methodology
3. Optimization
Tackling small problems
4. Futility of Individuality
Interdisciplinary, Hybrid
5. Publish or Perish
Do your own thing
Use your own acronym

20. Warning of the doorknob - escalation
Design a doorknob
Is a doorknob the
best way of
opening and
closing a door?
Is a door the best
way of controlling
access to your
office?
Do you really need
a traditional office
with four walls?
…
Is capitalist
democracy the best
way to organize our
economy?

22. Collaboration
Ability of large teams
to address large and
complex problems
EA
ST
EA + ST
Multiple viewpoints
and perspectives
Different people
working on different
scales
One scale isn’t
automatically better
than any other scale
Interoperability
between different
scales and viewpoints
Compare and contrast how EAs work
in teams with how STs work in teams?
23. Are we as good as we think we are?
“We are better than
anyone else at
abstraction and
generalization.”
“We are better than
anyone else at big
picture, joined-up
thinking.”
Abstraction
ungrounded
metaspeculation?
Big picture thinking
infinite escalation.
24. From “Best Practice” to “Next Practice”
Mainstream practices
have high consensus
but little systematic
evidence.
Emerging practices
have low
consensus, therefore
need a stronger
evidence base.
