linear cause-effect thinking is not sufficient
need a different way of thinking & seeing

creating a diagram
1. tell the story– ask questions, determine scope and focus question
2. collect variables– observable or measurable– behaviour over time
3. determine cause effect relations
4. look for loops– reinforcing, stabilizing
5. simplify– 7 ± 2 variables - remove unrelated variables– split up the diagram
6. identify possible interventions
