The Two-Door Framework, developed by Jeff Bezos, classifies decisions by reversibility. Type 1 decisions are one-way doors: irreversible or very costly to reverse, requiring deliberate analysis and senior judgment. Type 2 decisions are two-way doors: reversible, low cost to undo, and best made quickly by the smallest appropriate team. The central insight is that most organisations apply Type 1 process to Type 2 decisions, which creates bureaucratic drag without improving outcomes.
Where this came from
Jeff Bezos introduced the framework in Amazon's 2015 annual letter to shareholders. He was addressing a specific problem: as companies grow, they develop institutional processes designed to catch mistakes. Those processes are appropriate for consequential, irreversible decisions. The problem is that the same processes get applied to routine, reversible decisions, because the organisation cannot distinguish between the two. The result is slowness that is indistinguishable from institutional stupidity.
Bezos's letter described the failure mode precisely: "As organisations get larger, there seems to be a tendency to use the heavy-weight Type 1 decision-making process on most decisions, including many Type 2 decisions. The end result of this is slowness, unthoughtful risk aversion, failure to experiment sufficiently, and consequently diminished invention." His solution was not to move faster on everything but to be disciplined about which type of decision you are actually making before deciding how to make it.
The framework has since been widely adopted in technology product management, venture-backed startups, and management consulting as a diagnostic for organisational decision velocity.
How it works
The classification question is: if this turns out to be wrong, can I reverse it at reasonable cost and return to approximately my current position?
If yes, it is a Type 2 decision. Move fast. Assign it to the smallest team that has the relevant context. Set a deadline. Make the call. Treat a wrong answer as information, not a failure.
If no, it is a Type 1 decision. Slow down. Gather more information. Involve senior decision-makers. Use a structured analysis process. The cost of getting it wrong justifies the overhead of getting it right.
The practical insight is that reversibility is not the same as importance or size. A large project can be Type 2 if it is structured to be undoable. A small commitment can be Type 1 if it creates obligations that are costly to exit. A company signing a new office lease is making a Type 1 decision regardless of the absolute dollar amount, because leases are hard to exit. A company testing a new pricing page is making a Type 2 decision even if the potential revenue impact is large, because the test can be reversed.
The framework also applies to personal decisions. Choosing a city to live in is closer to Type 1. Choosing a gym is Type 2. Accepting a job at a company with a two-year vesting cliff is more Type 1 than it appears, because exiting before the cliff is financially costly. These classifications are worth making explicit before deciding how much analytical effort to invest.
When to use it — and when not to
The Two-Door Framework is primarily a meta-decision tool: it tells you how much process to apply to a decision before you apply any process to the decision itself. Use it at the start of any significant choice as a calibration step.
It is most valuable in organisations with multiple stakeholders where there is natural pressure to escalate everything to committee. Before scheduling the meeting, ask whether the decision is actually Type 1. If it is not, the meeting is overhead that adds delay without adding quality.
It is also valuable for personal decisions where you are procrastinating. Procrastination on Type 2 decisions is almost always a mistake: the cost of delay exceeds the cost of a wrong answer that can be corrected. Procrastination on Type 1 decisions is often appropriate: the cost of delay is lower than the cost of an irreversible error.
Where the framework needs supplementing: it does not tell you how to make either type of decision well. It tells you how much process to apply. For the content of the analysis, you still need the appropriate frameworks for the specific decision type.
Omission Bias
Omission bias is the tendency to judge harmful actions as worse than equally harmful inactions. In decisions, it means that failing to decide is psychologically more comfortable than deciding wrongly, even when the cost of inaction exceeds the cost of a reversible mistake. For Type 2 decisions, omission bias causes people to delay indefinitely on the grounds that they need more information, when the better move is to act, observe, and adjust. The failure to decide is itself a decision, and it is systematically underweighted.

How to apply it in practice
For any decision you are currently sitting on, write the classification question at the top of a page: "If this turns out to be wrong, can I reverse it at reasonable cost?"
Then list the specific costs of reversal: financial cost, time cost, reputational cost, relationship cost. If these are low across all dimensions, you have a Type 2 decision. Stop gathering information. Make the call today.
If reversal is genuinely costly, you have a Type 1 decision. The next step is to define what information would actually change your decision. Most people in Type 1 decisions delay because they are gathering information that will not change the outcome, rather than the specific evidence that would. Write down the question: "What would I need to learn to change my current preferred answer?" Gather that and only that.
For recurring decisions in an organisation, map your decision inventory once a quarter. Tag each recurring decision type as 1 or 2. For all Type 2 decisions, define the smallest team that has the competence to make them and delegate permanently. For Type 1 decisions, define the process and the decision-makers explicitly. This one exercise, done properly, is one of the highest-leverage investments any team can make in its own decision quality.

Frequently asked questions
What is the Two-Door Framework?
The Two-Door Framework is a decision classification model developed by Jeff Bezos. Type 1 decisions (one-way doors) are irreversible or very hard to reverse and require careful, deliberate analysis before acting. Type 2 decisions (two-way doors) are reversible and can be undone if wrong, so they should be made quickly, often by a small team or an individual rather than by committee. The framework's primary purpose is to stop organisations from treating reversible decisions with the same process overhead as irreversible ones.
How did Bezos use the Two-Door Framework at Amazon?
Bezos introduced the framework explicitly in Amazon's 2015 annual shareholder letter, where he warned that high-judgment executives make the error of applying a heavyweight decision process to decisions that do not require it. He argued that as companies grow, there is a natural tendency to treat all decisions like Type 1, which causes the organisation to slow down and lose the speed advantages of a startup. He pushed Amazon to push Type 2 decisions down to the smallest possible team and keep Type 1 decisions at the appropriate level of senior oversight.
How do you classify a decision as Type 1 or Type 2?
Ask two questions: If this turns out to be wrong, can I undo it at reasonable cost? And if I undo it, do I return to roughly the same position I am in now? If both answers are yes, it is a Type 2 decision. If undoing it is expensive, publicly embarrassing, legally complicated, or structurally impossible, it is a Type 1 decision. Most hiring decisions are Type 2 (you can let someone go). Acquisitions are Type 1. Signing a long-term lease is closer to Type 1. Changing a product feature is usually Type 2.
What are examples of Type 1 and Type 2 decisions?
Type 1 examples: entering a new country market, making an acquisition, launching a major product line, selling a significant equity stake, relocating company headquarters, choosing a technical architecture that will be costly to change. Type 2 examples: changing a pricing page, testing a marketing message, hiring for a new role, redesigning an internal process, adjusting a product feature, choosing which conference to attend. The key variable is not size or cost but reversibility.
