Complex Context

Systems Thinking

Decision Making

Copyright, 2014 | K. Wahba, PhD | DM-ST3

Processes are there

And are known

No secrete about them, only the execution is the

challenge

Page 4: Khaled wahba msm

Decision Making

Copyright, 2014 | K. Wahba, PhD | DM-ST4

The Big Question!

Are all of us supposed to make the

right Decision?

In order to understand the world quickly, look at

the extremes

Page 5: Khaled wahba msm

Decision Making

Copyright, 2014 | K. Wahba, PhD | DM-ST5

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!

Page 6: Khaled wahba msm

Decision Making

Copyright, 2014 | K. Wahba, PhD | DM-ST6

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

them

Page 7: Khaled wahba msm

Decision Making

Copyright, 2014 | K. Wahba, PhD | DM-ST7

So today is

about how to make

right

Decision

Page 8: Khaled wahba msm

Decision Making

Copyright, 2014 | K. Wahba, PhD | DM-ST8

So today is

NOT

about how to make

Decision

Page 9: Khaled wahba msm

Decision Making

Copyright, 2014 | K. Wahba, PhD | DM-ST9

So today is

about how to make

wrong

Decision

Page 10: Khaled wahba msm

Decision Making

Copyright, 2014 | K. Wahba, PhD | DM-ST10

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

Page 11: Khaled wahba msm

Decision Making (The Mind)

Copyright, 2014 | K. Wahba, PhD | DM-ST11

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)

Page 12: Khaled wahba msm

Decision Making

Copyright, 2014 | K. Wahba, PhD | DM-ST12

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

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)

Page 18: Khaled wahba msm

Decision Making

Copyright, 2014 | K. Wahba, PhD | DM-ST18

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?

Page 19: Khaled wahba msm

Complexity

Page 20: Khaled wahba msm

Complexity

20

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

Copyright, 2014 | K. Wahba, PhD | DM-ST

Page 21: Khaled wahba msm

Complexity Defined

21

The Oxford Dictionary defines something as

"complex" if it is "made of (usually several)

closely connected parts"

23

A system would be more complex if more parts

could be distinguished, and if more

connections between them existed

25

The aspects of distinction and connectiondetermine 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

Policy Resistance:

The Law of Unintended Consequences

The counterintuitive behavior of social

systems

make it worse

Policy may create unanticipated side

effects

Attempts to stabilize the system may

destabilize it

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

Page 45: Khaled wahba msm

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

A Social System has resisted a policy

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

Page 70: Khaled wahba msm

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

Page 71: Khaled wahba msm

Systems Thinking

71

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.

Copyright, 2014 | K. Wahba, PhD | DM-ST

Page 72: Khaled wahba msm

Systems Thinking

72

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

study the whole thing. Copyright, 2014 | K. Wahba, PhD | DM-ST

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

Page 76: Khaled wahba msm

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)

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

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
