2. Today I am sharing with you
Decision Making
Complex Context
(Complexity)
Systems Thinking
Copyright, 2014 2 | K. Wahba, PhD | DM-ST
3. Decision Making
Processes are there
And are known
No secrete about them, only the execution is the
challenge
Copyright, 2014 3 | K. Wahba, PhD | DM-ST
4. Decision Making
The Big Question!
Are all of us supposed to make the
right Decision?
In order to understand the world quickly, look at
the extremes
Copyright, 2014 4 | K. Wahba, PhD | DM-ST
5. Decision Making
1) What would happen to our World if we all
make the right decision?
and
2) What would happen to our World if we all
make no decision?
Answer!
is it the Bottom-Line-Answer (final conclusion)?
1) Life Stops!
2) Life Does not Move!
Copyright, 2014 5 | K. Wahba, PhD | DM-ST
6. Decision Making
So we are now happy that we still
make wrong decisions
Life is about making wrong
decisions
Everyone so far is struggling and
busy to make the right decision
Ok, let them do that, life will stop for

7. Decision Making
So today is
about how to make
right
Decision
Copyright, 2014 7 | K. Wahba, PhD | DM-ST
8. Decision Making
So today is
NOT
about how to make
right
Decision
Copyright, 2014 8 | K. Wahba, PhD | DM-ST
9. Decision Making
So today is
about how to make
wrong
Decision
Copyright, 2014 9 | K. Wahba, PhD | DM-ST
10. Decision Making
We wonder!
Why wrong decision could be right one? and why
right decision could be wrong one? and when the
right is right and when the wrong is wrong?
It is all about HOW the mind is working during the
decision making process
Copyright, 2014 10 | K. Wahba, PhD | DM-ST
11. Decision Making (The Mind)
Philosophical View:
Plato: Chariot pulled by two horses, Driver, with two
Horses
Metaphor: Charioteer (Reason) & Horses (Emotion)
Psychological View:
Freud: ID & Ego (Conflict between Desire, Rational Brain)
William James: Two Thinking Systems
S1 -- Rational and Deliberate
S2 -- Quick and Effortless, Emotional
Neuro-Scientifical View:
Rational (logic) vs. Emotional (passion)
Dopamine (neurotransmitter), Orbitofrontal Cortex (OFC)
Copyright, 2014 11 | K. Wahba, PhD | DM-ST
12. Decision Making
It is all about how we see our world and
how we see our reality
BUT in fact we don’t see our reality and
again we are lucky that we don’t see it ;)
We perceive it not see it
Because if we see it, it means we all live
the same single reality and hence we will
make the right decision again, then Life
stops
Visually I propose this view
Copyright, 2014 12 | K. Wahba, PhD | DM-ST
16. Decision Making
TRUTH
?
Reality
!
We deal with
its Image
(Reality)
Truth
is
Hidden
Our
Mental Model
Copyright, 2014 16 | K. Wahba, PhD | DM-ST
17. Decision Making
We are the Blind photographer who exploring the
Truth with our own Camera (Mental Model) to picture
it
My Camera (MM) is unique, with different Lenses,
Power, Resolutions, Detailing, etc …
Who has the best Camera (MM) will have better
vision about the Truth (But never the Truth)
So, our focus now became how to get the best
Camera (MM), but still we need to interpret the
Picture (Reality)
Then the chance for better decision (maybe wrong,
maybe right)
Copyright, 2014 17 | K. Wahba, PhD | DM-ST
18. Decision Making
The quality of our interpretation
depends on the amount of details
(Complexity) we have in this picture
(Reality)
Then what defines the degree of
Complexity?
Copyright, 2014 18 | K. Wahba, PhD | DM-ST
20. Complexity
Complexity has turned out to be
very difficult to define (Heylighen)
The dozens of definitions that
have been offered all fall short in
one respect or another
The original Latin
word complexus, which signifies
"entwined", "twisted together"
In order to have a complex you
need two or more components,
which are joined in such a way
that it is difficult to separate them
20

21. Complexity Defined
The Oxford Dictionary defines something as
"complex" if it is "made of (usually several)
closely connected parts"

Copyright, 2014 | K. Wahba, PhD | DM-ST
23. Complexity Defined
A system would be more complex if more parts
could be distinguished, and if more
connections between them existed
23
Copyright, 2014 | K. Wahba, PhD | DM-ST
24. Complexity: Two-Dimensional
The aspects of distinction and connection
determine two dimensions characterizing complexity

Copyright, 2014 | K. Wahba, PhD | DM-ST
25. Complexity: Two-Dimensional
The aspects of distinction and connection
determine two dimensions characterizing complexity
Distinction corresponds to variety, to heterogeneity, to
the fact that different parts of the complex behave
differently
Connection corresponds to constraint, to the fact that
different parts are not independent, but that the
knowledge of one part allows the determination of
features of the other parts

Lucky Medical Doctor!!
Tools, Equipment, Technology …
The X-ray, MRI, Ultrasound …
Different Views, and Angles and Details …
Filter (not every details) …
So, What about us?
How to see the complexity in our reality?
How to deal with it?
We need Tools, Methods to intervene properly and timely
Systems Thinking …

43. Policy Resistance:
The Law of Unintended Consequences
The counterintuitive behavior of social
systems
People seeking to solve a problem often
make it worse
Policy may create unanticipated side
effects
Attempts to stabilize the system may
destabilize it
Decisions may provoke reactions by others
seeking to restore the balance we upset Copyright, 2014 | K. Wahba, PhD | DM-ST 43
44. Romanian Birth Rates: Facts
Crude birth rate in late 1960’s was 15 per 1000
per year
Government imposed policy to stimulate the birth
rate
Modest tax incentives for larger families
Importation of contraceptive devices was outlawed
Propaganda campaigns praising the virtues of large
families
Abortion was banned
Copyright, 2014 | K. Wahba, PhD | DM-ST 44
45. Romanian Birth Rates: The results
Crude birth rate 40 per 1000 per year
Fastest growing nation
Birth rate began to fall within months
1970, it reached 20 per 1000 per year
1989, it reached 16 per 1000 per year
The same as in early 1960’s

69. What is a System?
It is collection of parts that interact with one
another to function as a whole.
Examples:
Mechanical Systems (thermostat)
Ecological Systems (population/food)
Biological Systems (digestive, body
temp.)
Social-economic systems (production)
Copyright, 2014 | K. Wahba, PhD | DM-ST 69
70. Systems Thinking … !!!
Systems Thinking is a paradigm and
methodology for dealing with complex situations
underlying business, economics, scientific, and social
systems.
Systems Thinking views the organization as a
whole and focuses on interdependencies and links
between various departments, functions and divisions
and how they impact each other and the entire
organization. Complexity is a new paradigm drawing
from Relativity and Quantum theories.
Copyright, 2014 | K. Wahba, PhD | DM-ST 70
71. Systems Thinking
Systems thinking is the process of understanding
how things influence one another within a whole.
In nature, systems thinking examples include
ecosystems in which various elements such as
air, water, movement, plants, and animals work
together to survive or perish.
In organizations, systems consist of people,
structures, and processes that work together to
make an organization healthy or unhealthy.
71
Copyright, 2014 | K. Wahba, PhD | DM-ST
72. Systems Thinking
Systems thinking is crucial to problem
solving including Economic, Social,
Organizational
No problem exists in isolation, all are part
of a larger system of interacting networks;
social networks, biogeophysical networks,
political networks, and economic
networks.
We can’t understand the behavior of
system by studying its parts; we need to
72
study the whole thing. Copyright, 2014 | K. Wahba, PhD | DM-ST
73. Systems Thinking Scope
Design of New Systems
Re-engineering or Improvement of Existing
Systems
Prediction of Behavior of Complex System

75. Systems Thinking Benefits
Systems thinking enables leaders and organizations:
Effectively deal with uncertainty and complexity
Foresee the consequences of their actions, policies and
strategies
Identify fundamental causes and solutions to chronic
problems
Avoid misjudging problem symptoms for their causes
Reconcile dilemma of short-term fixes vs long terms
strategies
Resolve endemic staff morale and productivity problems
Bring alignment of vision and action to teams and groups
Become a Living and Learning Organization
Copyright, 2014 | K. Wahba, PhD | DM-ST 75
76. Systems Thinking as Language
Systems Thinking provides a tool for
understanding complexity and dynamic decision
making
The Language …
Is visual and diagrammatic (CLD)
Has a set of precise rules
Translates perceptions into explicit pictures
Emphasizes closed interdependencies (circular
language)
Copyright, 2014 | K. Wahba, PhD | DM-ST 76

79. Causal Loop Modeling
According to P. Senge, 1990
Causal Loop Diagram provides “… a framework
for seeing interrelationships rather than things,
for seeing patterns of change rather than static
snapshots”
Causal Loop Diagram (CLD) is a tool for
revealing the casual relationships among a
set of variables (factors) operating in a
complex system
Copyright, 2014 | K. Wahba, PhD | DM-ST 79
80. Leverage versus Solution
System Thinking is not about Problem
Solving Methodology (by product)
Problem is not isolated and unstructured
Short term, local, optimal, neat, content,
symptoms
Leverage
It refers to actions or interventions that can
have a lasting impact on the system,
Long term, global, fundamental, realistic,
content and context, cause

81. Systems Archetypes
Systems Archetypes are generic systems
models or templates that represent a wide range
of situations

processes
