Borrowed from STW/STiA Certification program to help develop insights regarding situations of interest to New Community Paradigms. There are a number of things should be considered to ensure a view of the relevant influences.

We create the future as a result of the manner in which we choose to engage with situations which concern us. There is a also a video for this insight.

Based on 1990 SDR Article. Control systems act to make their own input match internal standards or reference signals. Competent control systems create illusions of stimulus response causality. Stimulus-response theory can approximate the relationship between disturbance and action, but it can't predict the consequences of behavior. These consequences are maintained despite disturbances.

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.

When one undertakes to create a model there are a number of guidelines that are considered essential for consideration if there is to be a success with the model.

This common archetype of systems that include relapse or recidivism allows exploration of the unintended effects of increasing upstream capacity and swamping downstream capacity. The increase in the relapse rate eventually returns to swamp upstream capacity as well. A social welfare example, based on a TANF case study, from How Small System Dynamics Models Can Help the Policy Process. N. Ghaffarzadegan, J. Lyneis, GP Richardson.

The Home Heating System can be used to demonstrate how we get caught in dilemmas and become victims of ourselves.

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.
