A random walk demonstration using an ABM. As individuals drink more they become more intoxicated and their walk becomes more random. And when they drink to much it finally kills them.
We are embedded in a larger system and unless we realize it an act accordingly we are likely to be the victim of it. From Introduction to System Dynamics: Overview by John Sterman
An example of why it's so critical to understand where the boundaries are when considering a system. (developed from Eric Wolstenholme's Archetype examples by Gene Bellinger)
Often times there are a number of parameters in a model you want to set to specific values and run the model to demonstrate a particular behavior. When there are several variables involved remembering the setup is often difficult and takes time. And can you demonstrate the behavior when you're not there? Developing scenarios with Button scripts is a quick way to overcome these difficulties.
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.
A system is an entity that the existence of which is maintained via the mutual interaction of its parts and which demonstrates characteristics not exhibited by any of its parts.
Use a savings account 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 growth producing reinforcing loop.
Discussion groups, or bulletin boards if you prefer, come in numerous forms though for all their forms they are all pretty much the same. And, if you've found your way here then you probably belong to one or more of them.

The predicament forcing us toward virtual collaboration and our learning about relationships is hopefully encouraging us toward the systemic perspective.
