Type 1 vs Type 2 Decisions

Bezos's Type 1 vs Type 2 framework is the single most useful piece of leadership math: classify every decision by reversibility before discussing it. Type 1 (one-way doors) are irreversible or near-irreversible — selling the company, choosing a co-founder, raising a Series A on punitive terms. These deserve deep deliberation. Type 2 (two-way doors) are reversible — pricing tests, hiring decisions, feature launches. These deserve speed. Bezos's 2015 shareholder letter quantified the leverage: '90% of decisions in any company are Type 2 and should be made fast and decentralized.' Companies that treat all decisions as Type 1 die of slowness. Companies that treat all decisions as Type 2 die of recklessness. The discipline is naming which is which BEFORE arguing about the answer.

The Trap

KnowMBA POV: Type 2 decisions get over-deliberated and Type 1 decisions get under-deliberated. Both errors are systematic. Why? Type 2 decisions feel scary in the moment (fear of making the wrong call) so leaders escalate them. Type 1 decisions feel exciting (fundraising! acquisition! pivot!) so leaders rush them. The result is the inverse of what's optimal: small reversible bets eat weeks of leadership time, while million-dollar irreversible bets get decided over dinner. The cure is the explicit classification step before any discussion of the substance.

What to Do

Add one mandatory step to every meaningful decision: classify it. (1) Write the decision in one sentence. (2) Ask: 'If we get this wrong, how long and how expensive is the reversal?' < 3 months and < 5% of budget = Type 2 (decide in 48 hours). > 12 months or > 20% of budget = Type 1 (deserves a 6-page memo and the full leadership team). (3) Push Type 2 decisions DOWN — they should not require executive approval. (4) Pull Type 1 decisions UP and SLOW them — they deserve written analysis, pre-mortem, and dissent surfacing. (5) Track decisions in a log: classification, decision time, outcome at 6 months. Audit yourself for misclassification.

Formula

Decision Type = f(Reversibility Time, Cost to Reverse, Optionality Lost)

In Practice

Bezos's 2015 shareholder letter introduced the principle to the public: 'Some decisions are consequential and irreversible or nearly irreversible — one-way doors — and these decisions must be made methodically, carefully, slowly, with great deliberation and consultation. If you walk through and don't like what you see on the other side, you can't get back to where you were before. We can call these Type 1 decisions. But most decisions aren't like that — they are changeable, reversible — they're two-way doors. If you've made a suboptimal Type 2 decision, you don't have to live with the consequences for that long. You can reopen the door and go back through.' Source: Jeff Bezos, 2015 Letter to Shareholders.

Pro Tips

01
The 'reversibility test' is concrete: 'If we make this decision today and it's wrong, what does the recovery look like in 6 months?' If the answer is a sprint of work, decide today. If it's a 12-month re-platform, slow down.
02
Type 1 decisions are rare. In a typical week of leadership decisions, expect 1-2 Type 1s and 30-50 Type 2s. If your week has 10 Type 1s, you're probably misclassifying — or making decisions that should have been delegated.
03
Hiring is the most commonly misclassified decision. Hiring a junior engineer is Type 2 (you can let go in 90 days). Hiring a VP of Sales is closer to Type 1 (their decisions reshape the org for 18+ months even after they leave). Most companies treat both with the same process.

Myth vs Reality

Myth

“Bigger budget = Type 1 decision”

Reality

Cost is one signal but not the controlling one. A $500K marketing test that's measurable in 90 days is Type 2 even though it's expensive. A $50K decision to publicly take a political stance is closer to Type 1 because the brand impact is hard to reverse. Reversibility, not cost, is the lead variable.

Myth

“Type 2 decisions don't need analysis”

Reality

Type 2 decisions deserve PROPORTIONATE analysis — usually a few hours, not weeks. The mistake is binary thinking. A Type 2 decision still benefits from a 1-page write-up; it just doesn't need a 6-page memo and 3 reviews.

Amazon

1997-Present

success

Bezos formalized Type 1 vs Type 2 in his 2015 shareholder letter, but the principle had been operating internally since the late 1990s. The classification is encoded in Amazon's two-pizza team structure: small autonomous teams have full authority over Type 2 decisions, with no executive approval needed. Only true Type 1s — major capex, irreversible architecture, M&A — escalate to Bezos's S-team. This is why Amazon ships ~3,000 features per year on AWS alone with a 1.5M-employee company.

Amazon's velocity isn't from working harder — it's from classifying decisions correctly. The 90/10 split (Type 2 / Type 1) is preserved by the org structure: small teams with autonomy on Type 2 + S-team review on Type 1.

Sears

2000-2018

failure

Hypothetical: Sears under Eddie Lampert systematically misclassified its largest strategic decisions. The decision to under-invest in e-commerce was treated as a Type 2 (we can ramp up later) when it was actually a Type 1 (every year of underinvestment foreclosed market position). Meanwhile, the company spent enormous executive bandwidth on small reversible decisions like store layout changes. The misclassification compounded: by 2015 the e-commerce gap was unrecoverable and the company filed bankruptcy in 2018.

When you misclassify a Type 1 as a Type 2, you're not 'moving fast' — you're sleepwalking through a permanent commitment. The cost of misclassification is asymmetric: under-deliberating a Type 1 ends companies; over-deliberating a Type 2 just slows them down.

Decision scenario

The Acquisition Offer

You're CEO of a $30M ARR SaaS company. A larger competitor offers to acquire you for $200M cash. Your CFO wants to evaluate over 30 days. Your VP of Engineering says 'this is a no-brainer, take it.' Your board chair says 'we should think about this carefully but not too long.' The offer expires in 21 days.

Decision Type

Decision 1

You need to classify the decision before discussing the answer. Selling the company is the canonical Type 1 — fully irreversible. But the offer expiration creates time pressure that pushes some leaders to treat it as Type 2.

Treat the time pressure as the dominant signal: decide in 1 week using the leadership team's gut, optimize for not letting the offer expireReveal

You're treating a Type 1 decision (selling the company is fully irreversible) as a Type 2 because of the time constraint. Your team spends a week debating without proper diligence — no comparable transaction analysis, no scenario modeling, no honest conversation about post-close execution risk. You accept the offer at $200M. Two years later you discover comparable deals went for 9-10x ARR and you left $80M on the table. The decision can't be undone.

Decision Time: 1 week (rushed)Value Left on Table: ~$80M (vs comparables)Post-Close Regret: High

Classify as Type 1: hire an investment banker IMMEDIATELY for parallel diligence, request a 14-day offer extension, run a quiet outreach to 2-3 strategic alternates, write a 6-page decision memo with scenariosReveal

Correct. Type 1 decisions deserve deliberation regardless of artificial time pressure. The banker creates competitive tension (a second bidder emerges at $245M), the offer extension is granted (it almost always is for a serious buyer), and the 6-page memo forces honest analysis of the post-close team risk. You ultimately accept a $235M offer with better earnout terms. The discipline of classifying first preserved $35M+ of value AND surfaced execution risks the team handled in the contract.
