When to use

"Use when a decision's benefits are clear but the downstream negative consequences are not. Trace second and third-order effects, focusing on what breaks, degrades, or creates new obligations."

Example

"Adopting a new CI/CD tool (first order — faster deploys). Second order — team must learn the tool, existing scripts break, deployment frequency increases but so does rollback frequency. Third order — increased rollback frequency normalizes failed deploys, reducing quality pressure."

Common misuse

"Tracing only negative second-order effects and ignoring positive ones. The technique is about completeness, not pessimism. A balanced analysis traces both cascades."
