What is it?

Amazon's One-Way / Two-Way Door Decisions is a simple mental model Jeff Bezos popularized to calibrate your decision-making tempo.

At its core, you categorize choices as either two-way door, low-cost, reversible moves you can test, learn, and roll back, or one-way door, high-stakes, irreversible commitments that demand rigorous analysis, alignment, and risk mitigation. By labeling each decision upfront, you avoid overbuilding process overhead around fast, safe experiments, and focus heavy-weight approval where it really matters. This framework solves the fundamental tension between speed and caution, giving you clear criteria to push the gas pedal on low-risk bets while applying brakes on high-risk ones. Two-way doors power rapid iteration and user feedback loops, letting your team deploy features, tweak designs, or adjust pricing tests in hours or days. One-way doors cover decisions like infrastructure rewrites, M&A terms, or core architectural shifts that require cross-functional sign-off, budget reserves, and deep-dive due diligence.

Lean into this model to slash bureaucracy, empower your team to move fast, and save intensive review for the bets that deserve it.

Why it matters?

By explicitly separating reversible experiments from irreversible strategic bets, you slash decision latency, unlock rapid iteration loops, and avoid project paralysis. This turbocharges your innovation velocity, more tests in days, fewer boardroom bottlenecks for minor tweaks, while ensuring your biggest commitments get the scrutiny they deserve, ultimately driving faster product-market fit, higher customer satisfaction, and a more resilient growth engine.

How it works

Growth co-pilot turns your toughest product questions into clear, data-backed recommendations you can act on immediately.

1

List all pending decisions

Write down every choice looming on your roadmap or backlog so nothing slips through the cracks.

2

Classify reversibility

For each decision, estimate the cost, time, and complexity to roll it back, low-cost equals two-way door; high-cost equals one-way door.

3

Fast-track two-way doors

Assign minimal process, set clear success metrics and automatic rollback triggers to learn quickly without fear of sunk cost.

4

Rigorous review for one-way doors

Convene stakeholders, run risk analyses, draft contingency plans, and lock in budgets before you commit.

5

Capture and iterate

After the decision plays out, log outcomes and lessons learned to refine your reversibility thresholds and keep your speed/caution calibration razor-sharp.

Frequently asked questions

What exactly is a two-way door decision?

A two-way door decision is any choice you can reverse or adjust with minimal cost, think A/B tests, UI tweaks, or pricing experiments. You can push fast and pivot when data points the way.

How do I know if a decision is one-way and needs more scrutiny?

Estimate the rollback cost in dollars, time, and resource drain. If reversing the change trips major tech debt, legal hurdles, or budget, treat it as a one-way door with full stakeholder alignment.

Can I apply this model to non-technical decisions?

Absolutely. Use it for marketing campaigns, vendor contracts, sales compensation plans, anywhere you can quantify reversibility and tailor your approval process accordingly.

How does this fit into agile workflows?

Inject the classification step into your backlog grooming. Tag each user story or epic as one-way or two-way door, then adjust your sprint ceremonies and Definition of Done based on its category.

What's a real-world Amazon example?

Amazon famously rolled out Prime two-day shipping as a two-way door: they tested regions incrementally and hooked up rollback triggers, then once the model proved profitable, it became a one-way core offering.
