SD Humour

Post by fabiansz@consultant.com »

Bob,

Id surely go for visual learning/verbal debriefing, or to
experiential icebreakers.

In some of the presentations I make, I use to project some
cartoons like those generated by Larsen where I could easily
deduce a systemic and/or dynamic mini-debriefing.

There are also some selected Dilberts cartoons you could
shurely pick and use. Some Arthur Andersen ads also may help.

Go for the ST Playbook, by Dennis Meadows/Linda Booth Sweeney
for the experiential part.

Best Regards from Buenos Aires,

May I build on the spirit of Andrew Jones lovely response to this question?


What a detail complexity question!
You should think in terms of the modes of behaviour of electrical energy
usage.
Or the modes that describe transitions from one energy source to another.
Thinking more braodly yet, how might we create a causal theory which
accounts for the emergence of organisms who use visual information and are
therefore interested in light sources of any kind.

Lets try to take the long view here, people!

SD Community;

I have an opportunity to present an introduction to System Dynamics, its applications and relationships to the emerging field of Knowledge Management to business executives and public sector officials in a "travelling road show" across Canada later this year. Like may of us in our global community I tend to be rather intense about the value of the SD perspective and often tend to disregard the human touch.

If any of you have stories, jokes or puns that might add a lighter touch to the practice of what is essentially a scientific discipline I would dearly love to hear about them.

For those of you not in British Commonwealth countries I wish to remind you that the Brits did indeed invent humour and the word itself properly has a "u" in it.

Poking a little fun at ourselves:

At a party one evening, there was a physician, an engineer, and a system dynamist gathered
around having a small discussion proposing whose profession was the oldest. "Well," began
the physician, "as you can remember from the Book of Genesis, God made Eve from Adams
rib. That is a medical procedure, therefore, being a physician is the oldest profession in
the world."

"Not so fast," retorted the engineer. "Remember also in the Book of Genesis that prior to
your medical procedure, God made the heavens and the earth from all the chaos. Well that
is an engineering feat, therefore, being an engineer is the oldest profession in the
world."

The system dynamist just looked at the other two, winked, and said, "who do you think
created all the chaos?"


Cordially,

Bob Bois

How many system dynamicists does it take to screw in a lightbulb?

What a silly, detail-complexity question! Wouldnt you rather explore the
structure that drives the long-term behavior mode of the "indicated bulb
screwers" -- s-shaped growth, growth and overshoot, oscillating, or other?

Wait. Lets back up and ask why we want the lightbulb screwed in. What
problem are we trying to solve?

Or:

None. Theyd rather sit in the dark and argue about whether systems
thinking is a subset of system dynamics, or vice versa.

Or:

Who cares. By the time theyre done building the model, the sun will be up.

>>How many system dynamicists does it take to screw in a lightbulb?


I think this question is best understood by considering how some of the
great members of the field might tackle the question:

The Pugh-Roberts folk might develop a sophisticated model to predict when
the bulbs would burn out. Ventanna might add a high tech algorithim to
optimally schedule the staff of bulb replacers.

Jack Homer would do the same thing, but only for those light bulbs used in
crack houses and as motorcycle headlights.

David Kreutzer, George Richardson and David Andersen might get the light
bulbs themselves invovled in a discussion and group model building effort
to understand why they so often get burned out.

Peter Senge could pick this up, but would probably refocus the discussion
on whether they aspire to burn out or just to fade away

Mark Paich and his maintenace-minded colleagues would suggest its better to
replace the bulbs proactively rather than wait for them to burn out.

Those from the larger consulting companies might question the value
proposition of the light bulb and perhaps suggest that the service of
illumination provision be outsourced to a cheaper external provider.

Dana Meadows would probably ask whether we need so many light bulbs in the
first place.


And Jay Forrester...


well, after admonishing us for taking such a low leverage approach to the
problem, hed redesign the system so those silly bulbs didnt burn out so
often in the first place.
