Initial causal loop diagram for the influences leading to the acceptance of Systems Thinking.

This Romeo and Juliet Model was adapted by Geoff McDonnell from Michael J Radzicki (1993) Dyadic processes, tempestuous relationships, and system dynamics, System Dynamic Rev. 9 (1) :79-94

This is a more Traditional Career Model of how education works, with an increased lifetime earnings from going to college. The following are links to the other two models in the series.

• Loan Cost Model
• Savings Model

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.

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.

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 9781 for a simulation of this model.

Investigations into the relationships responsible for the success and failure of nations. This investigation was prompted after reading numerous references on the subject and perceiving that *Why Nations Fail: The Origins of Power, Prosperity, and Poverty* by Acemoglu and Robinson seem to make a great deal of sense.

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 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?

While all things are related for a particular situation all things are not relevant. We need to develop a simplified model of reality which depicts those interactions which are responsible for the patterns of behavior and current situation. We want the simplest model which enables the requisite understanding. This is no easy task though.

Understanding relationships is the foundation of effective problem solving. Though relations exists on multiple levels.

Purpose: Employ the Mono Lake model adapted from "Modeling the Environment" by Andrew Ford as a basis for developing a set of guidelines to support asynchronous multi-user model development.

Mono Lake is an ancient inland sea on the eastern side of the Sierra Nevada. From a policy point of view Mono Lake is the story of how a handful of people began a campaign to save a dying lake.
