The Two-Door Framework

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.
