Systems Thinking Vocabulary Global Studies – Atkins – Fall 2010 As a class we created a “system” outside to illustrate these ideas with the “connection circle” exercise. Key elements of a system are: change over time – the behavior of the system changes as time passes interdependence – elements of a system affect each other; the nature of the system is defined by the effects of the interdependencies, rather than just by the elements of the system feedback – an effect of the system re-entering the system as a cause leverage – considering where actions and changes can lead to significant, lasting improvements structure generates behavior – the way that things are organized creates the behavior we see delays – time lags between actions and effects. And effects and actions boundaries – definition of all that is required to produce the behavior of the system and elimination of all else
