• Cause-Effect separated in time
& space
• Sense → Analyse → Respond
Simple
• Known
• Cause-Effect perceivable,
predictable, repeatable
• Sense → Categorise → Respond
Complex
• Retrospectively Coherent
• Cause-Effect not repeatable
• Probe → Sense → Respond
Chaos
• Incoherent
• Cause-Effect not perceivable
