A Systems Thinking tool. Appears in some Jerry Weinberg books.

Each node represents a measurable quantity (not an idea, process, etc.). Arrows between nodes show effects been quantities.

A promising qualitative modelling technique.

• the challenge I see: this is good at communicating the model in your head. But can't you end up with an infinite number of causes and effects? How do you "decide" which ones are most significant? (Society Design context)

[Esther Derby] article using one for modelling [Organizational Change]

Similar: [Cause And Effect Diagram] (difference as I perceive it: [Ishikawa Diagram] focuses on a single failure event (binary) and works backwards to identify causes, whereas Diagram Of Effects may identify multiple "effects", each treated as a measurement, and specifies how a given node changes an effect node positively or negatively.)

  • including an [Ishikawa Diagram].
    

  • The greatest advantage of logico-linguistic models over the Ishikawa type is the fact that they can cover all logical possibilities.

aka [Causal Loop Diagram], [Diagram Of Ultimate Effects], [Diagram Of Possible Effects]
