Causality

A logical link between events where a cause precedes an effect and altering the cause alters the effect. “Causality explains the interrelatedness and interdependency of the elements. Interrelatedness is the connection between the elements of the set that make up the system and implies that the system taken as a whole has properties that differ from those of the simple sum of the effects of the individual relationships between pairs of elements. Interdependency is more specific and is the way relationships are conducted.” Systems Thinking in Foresight.
