This page contains a set of models associated with the LinkedIn discussion which was an endeavor to develop a Systemic Perspective associated with Chris Argyris' "Teaching Smart People How to Learn" article.

Reinforcing Loop/SFD Simulation allow one to experience the explicit implications of the interactions.

Faced with a performance gap the two most obvious responses are to work harder or work smarter. There are trade offs associated with each, some obvious, some not so obvious.

Use a bathtub model to investigate the manner in which inflows and outflows govern the quantity of a stock. Extend the structure to create and investigate the relationships of a goal seeking balancing loop.

The delays associated with adjusting the shower is a very common example of the Balancing Loop with Delay Systems Archetype. 

The following model was submitted by Lise Inman & Keith Margerison for inclusion in the ILE currently under development. I think it's a useful model which gets interesting as the arrival interval gets smaller and the queue backs up. So, what do you think of the model and what insights can we surface with this model?

Demo of population growth with distinct agents.

Based on a dialogue on the System Dynamics mailing list regarding the current level of acceptance of System Dynamics after it has been promoted for over 70 years I dredged up the following set of influences as a thought exercise. This is an example of a Drifting Goals Archetype.

A simple agent based foraging model. Consumer agents will move between fertile patches consuming them.

Some people have found it easier to communicate interactions and their implications with Connection Circles rather than Causal Loop Diagrams.

The structure responsible for rabbit population growth.

There are things we can influence and usually a broader array of things we are concerned about though can't influence. It's important to know the differerence otherwise we waste our energies trying to change things we have no influence over. 

When endeavoring to develop an understanding of the nature of something it is generally useful to create a model of some type to aid in surfacing that understanding.

This is my first attempt at creating a simple Agent Based Simulation Model. Nothing fancy, just something that works.

Simple bathtub model to show the difference between Stock and Flow. Run the model with various values for filling and draining to see the implications.

Relative Control is one of the four generic archetypes developed by Eric Wolstenholme and maps to the Balancing Loop with Delay, Indecision, Limits to Results, Drifting Goals and Escalation Systems Archetypes.
