The model construction process is actually a balancing loop which endeavors to employ an abstract version of real events to form a model which produces conclusions and behavior which mimic the real events.

To develop insights regarding a situation of interest there are a number of things should be considered to ensure a view of the relevant influences.

There's actually more to filling a swimming pool with water than you might realize.

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 1899 for a simulation of this model.

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.

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

New Learning tend to reduce Outdated Thinking, Communicating & Learning though our Outdated Thinking, Communicating & Learning inhibits new learning. The question is then how do we break this cycle. Adopted from "An Introduction to Systems Thinking with STELLA" by Barry Richmond.

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.

The purpose of this model is to have the user change the value of stocks, flows and converters to experience a variety of different graphical results. Understanding this generic model is important pre-requisite to learning about intravenous drugs in the body, radioactivity, self-esteem, water flowing from a drain and many other basic natural systems.

If we pay close attention to our actions and the typical outcomes of those actions it would be evident that there are frequently occurring patterns that develop. And there is a relation between the patterns.
