Reversal Cost
Also: cost to undo · rollback cost · exit cost
What it would take to undo a decision — the element most often missing from a Gains / Gives-up / Reversal-cost analysis.
Why CCAR-P tests this
The exam wants you to notice when a proposal weighs gains and trade-offs but never states how hard the decision is to reverse.
Reversal cost is the price of undoing a decision after it ships: the effort, time, data migration, contractual exit, and trust required to roll back. In the Gains / Gives-up / Reversal-cost frame, it is the third leg — and the one most commonly omitted.
When a recommendation feels complete but something is off, the missing element is usually the reversal cost or the compliance posture. A proposal can list every benefit (Gains) and honestly name what you sacrifice (Gives up) yet still be incomplete because it never asks: if this is wrong, how expensive is it to walk back?
Reversal cost reframes risk as optionality. A cheap-to-reverse choice (a canary, a flagged rollout) can be made quickly on thin evidence. An expensive-to-reverse choice (a data-model migration, a public commitment, a regulated cutover) demands more proof up front because the exit is costly. The best answers make the reversal cost explicit and let it set the evidence bar.
Exam trap
When a well-argued option lists benefits and trade-offs but omits how hard it is to undo, the gap it is testing is almost always reversal cost (or compliance posture) — pick the answer that surfaces it.
