PLACES TO INTERVENE IN A SYSTEM (in increasing order of effectiveness)
- Constants, parameters, numbers (such as subsidies, taxes, standards).
- The sizes of buffers and other stabilizing stocks, relative to their flows.
- The structure of material stocks and flows (such as transport networks, population age structures).
- The lengths of delays, relative to the rate of system change.
- The strength of negative feedback loops, relative to the impacts they are trying to correct against.
- The gain around driving positive feedback loops.
- The structure of information flows (who does and does not have access to information).
- The rules of the system (such as incentives, punishments, constraints).
- The power to add, change, evolve, or self-organize system structure.
- The goals of the system.
- The mindset or paradigm out of which the system — its goals, structure, rules, delays, parameters — arises.
- The power to transcend paradigms.
- constants, parameters, numerical values (subsidies, taxes, reference values, etc.)
- the size of buffers and other stabilizing stocks relative to their flows.
- structure of material stocks and flows (transport networks, population age structure, etc.)
- the length of the delay relative to the rate of change in the system.
- the strength of the negative feedback loop is relative to the impact it is trying to compensate for.
- Gain to drive positive feedback loop.
- the structure of information flows (who gets information and who does not).
- system rules (incentives, punishments, constraints, etc.).
- the ability to add to, change, evolve, or self-organize the structure of the system.
- Goals of the system
- the idea or paradigm from which the system (its goals, structure, rules, delays, parameters) emerges.
- The power to transcend paradigms.
