Question
Ask how the system will respond to the intervention
Interventions change incentives and behavior as well as the target variable.
When it fits
- When a proposed fix assumes other actors and processes will remain unchanged.
When to avoid it
- A causal map is a hypothesis, not proof. Keep evidence, time scale, boundary choices and alternative explanations visible before acting on a loop.
A question to ask
Who changes behavior because of the intervention? · What new incentive is created? · What workaround becomes attractive? · Which downstream variable may move in the opposite direction?
Why it matters
For the proposed action, ask who adapts, what becomes easier or harder, which metric shifts, and what workaround or compensating loop could appear.
An example
A stricter approval gate reduces one error type but causes teams to batch changes, increasing queue delay and late integration risk.
Check your result
The intervention review includes at least one endogenous response rather than a static before/after story.
Keep this limit in mind
- A causal map is a hypothesis, not proof. Keep evidence, time scale, boundary choices and alternative explanations visible before acting on a loop.

Evidence and sources
System dynamics work emphasizes that well-intended interventions can be defeated by feedback-driven system responses, a pattern described as policy resistance.
A qualitative feedback story is not enough; links, delays and predicted behavior still need empirical or operational checking.
