Document Summary
Storing information means increasing the complexity of the mechanism. A stock is the foundation of any system. Stocks are the elements of the system that you can see, feel, count, or measure at any given time. It is a store, a quantity, an accumulation of material or info. A stock is the memory of the history of changing flows within the system. Examples: water in a bathtub, books in a bookstore, wood in a tree, money in a bank, self-confidence. A stock doesn"t have to be physical ie. good will reserve; supply of hope that world can be better. A stock changes over time through the actions of flow. Flows = arrowheaded pipes leading into or out of the stock: t on top=faucet can be turned higher/lower; on/off. Use behavior-over time graphs to learn whether the system is approaching a goal or a limit, and if so, how quickly.
