3Prologue A Systems Tale
- New CEO of noodle-producer discovers Too much
spaghetti on stock! - CEO calls Marketing Director Make your Job!
- Marketing Director creates a big campaign Take
two, pay one. - Campaign extremely successful 3 months later
store is almost empty. - CEO to Marketing Director Well done!
- At the same time Production Accountant reports
to Production Director Our sales increased
dramatically! - The forecast says that in six months our sales
will have doubled from 200 tons to 400 tons per
month! We have to increase production
dramatically to fulfill the increased demand! - After seeing the figures the Production Director
is shocked We are already running two shifts.
Now we have to introduce a night-shift, too...

5How did the Production Director react?
- He recognized the considerable gap between sales
and production. - He concluded that due to the forecast this gap
apparently will become even bigger. - He decided to expand capacities dramatically by
introducing a third (night) shift. All holidays
had been cancelled and new personnel was
recruited immediately. - He was absolutely determined to increase
production by one-third within six weeks.
6What actually happened with Spaghetti Sales?
- Customers ate as much spaghetti as usual.
- The extra spaghetti packs bought at the 2 for 1
campaign were stored at home in their kitchens
and pantries. - Thus after the Get 2 for 1 campaign spaghetti
sales actually decreased dramatically below the
200 tons p.m. average. - The non-systemic forecast led the production
completely into the wrong direction. At the end
of June the stock was even higher than before the
2 for 1 campaign.
PS In June the CEO fired the Marketing Director
who apparently had completely neglected his
duties in the months after the great 2 for 1
campaign.
7The very Beginning of Systems Thinking
An early record of Systems Thinking in Gen 3
Adam Eve in the Garden Eden, just having tasted
from the Tree of Knowledge.
- God asked Adam Did you eat from the tree I
forbid? - Adam Not I! That wife you gave me told me...
- God asked Eve What did you do?
- Eve Not me! The snake....
Adam and Eve invented one of the most powerful
and disastrous systems principles Shifting the
Burden.
8Shifting the Burden
- Systems Archetype, coined by Peter Senge
- A quick and dirty solution is applied for a
short-term benefit, avoiding a painful (but
necessary) fundamental solution - Aspirin against tooth-ache instead of consulting
a dentist - Debt Get the benefit now, pay later
- Spaghetti Production story with several
instances of SdB - Pyramid Games
- Pay me 1.000,- and I give you the right to look
for 3 people who - pay you 1,000,- each for the same right to look
for 3 other people each ... So yours (and their)
net gain will be - 2.000,- each and all will be happy... ???
9Shifting the Burden lethally Scylla and
Charybdis
- Episode from Homers Odysse Scylla is a
6-headed Monster which required from each passing
ship a man for each head. Clever captains who
avoided Scylla little later inevitably run into
Charybdis, a downward whirl swallowing the whole
ship and all men. - Systems Principle Sometimes painful (but
limited) sacrifices are necessary in time to
avoid a total disaster later.
Who avoids Scylla has no problems in the short
term but will surely be destroyed by Charybdis
in the long term.
10Systems Thinking Approaches - Overview
11My Definition of Systems Thinking
Systems Thinking has four interrelated dimensions
- Dynamical Dimension - Thinking in dynamical
processes over time beyond snapshot-thinking
understanding stocks vs. flows, delays,
oscillations... - Model Dimension - Thinking in Models /Awareness
of Systems mental models, modeling assumptions,
model-reality qualitative vs. quantitative
models - Feedback Dimension - Thinking in loops and
networks interrelated structures, indirect
effects, feedback loops, networks of
interrelations - Pragmatical Dimension - Steering of Systems
finding the "leverage point", counterintuitive
behavior, proper intensity and timing of actions.
Dealing with conflicts and impossible
situations.
This Definition integrates different views of
Systems Thinking!
12Mental Models What does this Photo show?

- The Text 25 Original Tabletten BAYER
enthaltend jede 0.0025g Heroin. hydrochlor.
Farbenfabriken vorm. Friedr. Bayer Co. Leverkusen.
What today is considered a dangerous illegal
drug, was invented by Bayer and one of their
best selling medicaments!
13The History of Heroin
- Invented on Aug 11th 1897 by Felix Hoffmann at
Bayer in Leverkusen. - Aim a non-addictive substitute for Opiates
(anti-pain-drugs). - Heroin became one of the best selling products of
Bayer Tons of Heroin were prescribed for an
amazing variety of diagnoses. - Taken orally no side effects and no addictive
potential - Misuse started in the 1920ies in the USA by
injecting high doses of Heroin intravascular. - In the 1930ies Bayer silently withdrew from
Heroin-production. - Heroin is still used in GB as one of the best
oral anti-pain-drugs. - Today Bayer produces Methadon as a substitute for
Heroin-addicts.
Only 11 days after having invented Heroin the
same Felix Hoffmann synthesized for the first
time Acetylsalicylacid Aspirin. It became
popular only after the decline of Heroin.

Multiplier Effect We

Yeq increases 1/s a
- Y 1000 s0,1 ? S 100, C 900 ? Equilibrium
at I 100 - I will be increased by 10 up to 110
- New Equilibrium at Y1100, S110, C990
- Multiplier effect an Increase of I by 10
increases Yeq by 1010100!
17The Multiplier Effect in practical Politics
- Key question Must the higher (additional)
investment be made only once or permanently every
period (month)? - Background in a statical model this question
does not even appear, because the model contains
no dynamics over time. - A Dynamical Model can easily made with Excel!
- The result of the dynamical modelling is
shocking The higher investment must be done
permanently each month in order to approach the
higher level of Equilibrium after about 3 years!
18 Systemic Escalations A Couple in Trouble (Paul
Watzlawick)
HE "I go to the pub, because you are always
complaining!"SHE "Im just complaining, because
you always leave me alone!
Both sides try to solve the problem (which is
seen in the other person!)
Systemic Structure Escalating Feedback Loop!
19The Couple in Trouble Behind the Scenes
- The systemic view reveals the escalation feedback
loop. - More of the same or When the solution is
the problem - The systemic solutions are exactly the opposite
of the non-systemic solutions - he stays home (ignoring her quarreling) or
- she stops quarrelling although he is going to the
pub. - The Couple in Trouble is a prototype of an
Aporetic Conflict - two contradicting positions
- BOTH are true or legitimate
- Both depend on each other one cannot exist wo.
the other - Aporetic Conflicts contradict the laws of Logic!
- Apories cannot be solved by means of a Hierachy!
20How can we learn Systems Thinking?
- The first step is Awareness of Systems
Principles! - Systems Thinking needs systemic denotations,
models and tools! (CLDs, Stock-Flow-Diagrams,
simulation models...) - Quantitative Systems Modelling expands Systems
Thinking capabilities drastically! - Practical Systems Management very often has to
deal with aporetic situations, which are
logically impossible and cannot be solved by
delegation in a Hierarchy!
Eating the fruit from the Tree of Knowledge is
not enough! Essential for successful Systems
Thinking is Metanoia - the willingness to shift
fundamentals of our thinking radically!

26Lessons from the Heroin Models
- Causal Loop Diagrams (CLDs) are useful tools!
- CLDs help to discuss a situation. Different
viewpoints can be clarified and checked more
easily. - The same situation can be modeled in different
ways. - CLDs allow a reflection of model assumptions.
- Small differences in a model might have
dramatical consequences. - What appears to be the solution at first sight,
might (via feedback) make the problem even more
severe!
Proper tools for systemic descriptions and
modeling (e.g. CLDs) are essential for systems
thinking abilities!
