Underachievement is one of the four generic archetypes developed by Eric Wolstenholme and maps to the Limits to Growth, Tragedy of the Commons, Attractiveness Principle, Growth and Underinvestment and Growth and Underinvestment with a Drifting Standard Systems Archetypes.

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

Cloud example. If you really want clouds a sources in your model it's pretty easy to create one.

This is a clone of My First Map being used to demonstrate the addition of images to make a map more visually appealing.

A simple Susceptible - Infected - Recovered disease as a stock and flow model.

Example of a Bathtub overflow without using an If-Then-Else statement.

Adopted from An Introduction to Systems Thinking with STELLA by Barry Richmond.

A model to use to demonstrate scenarios using button scripts.

Inventory Model v4.0 calculates min days inv & max days inv and makes adjustments for desired service level. See also: Inventory Model v3.0.

While these pictures represent very different things there is a common essence.

We begin with a Bank with $0 and Borrowers with $100. Every year the Bank loans the Borrowers money at some interest rate. If the Bank loans $50 at 10% interest in 20 years the bank will have all the money and the Borrowers will be broke.

While these pictures represent very different things there is a common essence.

Our actions are based on our beliefs and the results of those actions are the basis for our beliefs. The difficulty we create for ourselves is that we make assumptions as to how to interpret the results we select based on our beliefs. As a result we are often operating on a flawed perspective of reality.

A spatially aware, agent based model of disease spread. There are three classes of people: susceptible (healthy), infected (sick and infectious), and recovered (healthy and temporarily immune).

There are about fifteen known archetypes with an interesting set of relationships among them.

This is a template which one might use as a basis for creating Insight Maker Relationship models. Links have default style of the blue ones in the diagram. The easiest way to get the red dashed links is to CTRL+d to duplicate them and then connect where appropriate.

The typical approach to dealing with situations. We simply want them to go away.

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.

The limits to growth structure is based on the basic growth structure. And, as should be obvious, nothing grows forever as growth requires resources. Those required resources become a limits to growth. See also Archetypes.

Consider the following "Sustaining the Forest" model intended to provide another example of how unexpected the behavior of a web of extended interactions can be.
