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

Rich Pictures, Causal Loop Diagrams and Stock & Flow Simulation Models are the three types of models most commonly used.

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

Yesterday's actions are responsible for the world we experience today. And today's actions are responsible for the world that we will experience tomorrow. The "Creating the Future" model is intended to provide a better sense of the common process associated with the unexpected unfolding of the future..

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.

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.
