Document Summary
Def: how the variable of interest (the state) of the system changes over time. Most real world things are examples of a small set of patterns of behaviour ("modes") Def: an initial quantity of something starts to grow and the rate of growth increases with time. Def: the quantity of interest starts either above or below a goal level and over time moves toward the goal. Def: the quantity of interest fluctuates around some level. This is due to the state of the system constantly overshoots its goal, then undershoots. The system behaviour (which mode the system follows) is dependent on the loop"s structure. Cld"s are ways of visualising the structure of a system. It allows us to visualize how interrelated variables in a system affect one another. These diagram"s "tell the story" of the system. They help us to observe the pattern of behaviour and determine how the pattern is influenced by each variable.
