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

 The model starts in 1900. In the year 2000 you get the chance to set a new emission target and nominal time to reach it. Your aim is to have atmospheric CO2 stabilize at about 400 ppmv in 2100.  From Sterman, John D. (2008)   Risk Communication on Climate:  Mental Models and Mass Balance .  Science

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.

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.
