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

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.

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

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

A model to use to demonstrate scenarios using button scripts.

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.

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.

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.

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

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

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).

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.

This model is derived from the paper "Nobody Ever Gets Credit for Fixing Problems that Never Happened: Creating and Sustaining Process Improvement" by Nelson P. Repenning and John D Sterman. See Insight 752 for a causal loop version of this model.
