A framework Jeff Bezos uses to differentiate decision velocity. Type 1 decisions are one-way doors — consequential and irreversible, deserving slow deliberation, multi-expert input, and high confidence before commitment.
Type 2 decisions are two-way doors — reversible at low cost, deserving fast decisions made by individuals or small groups who can iterate as they learn. The most common organizational failure is applying Type 1 process to Type 2 decisions, which kills velocity without improving quality.
The second most common is applying Type 2 process to Type 1 decisions, which destroys value at scale.
