What Is a Two-Way Door Decision? | Vantage
Two-Way Door Decision A two-way door decision is one that is easily reversible. If the decision does not work out, you can walk back through the door and return to where you started with minimal cost. Most product decisions are two-way doors, but teams often treat them as irreversible.
Why two-way door decision matters
Teams that treat every decision as irreversible move slowly. Recognizing two-way door decisions lets you move fast on low-risk choices while saving deliberation for the truly irreversible ones. Jeff Bezos popularized this framework at Amazon.
How it works
Before making a decision, ask: if this does not work, can we reverse it? If the answer is yes with low cost, it is a two-way door. Ship it quickly and observe the results. Reserve extensive analysis and committee decision-making for one-way doors.
Common mistakes
Treating two-way door decisions as one-way doors (analysis paralysis)
Not identifying the reversal mechanism before deciding
Confusing low-stakes with low-effort (a decision can be easily reversible but still require effort to implement)
Not tracking which decisions were two-way so you can reverse them if needed

How Vantage relates
Vantage supports rapid experimentation for two-way door decisions: generate a PRD quickly, create tickets, and ship. If the feature does not work, the PRD versioning system preserves the context for the next iteration.
