Most bad decisions aren't bad judgment, they're the right judgment applied to the wrong kind of decision. A reversible, cheap choice deserves a different process than an irreversible, expensive one. Knowing which framework to use is half the skill. Executing it is the other half.
Bezos's framing. Two categories:
The mistake most orgs make: treating Type 2 decisions like Type 1 (too slow), and Type 1 decisions like Type 2 (too careless). Get the type right first. Then pick the framework.
For decisions that span teams. Name each role explicitly:
The critical thing is that D is a single person. Not a committee. Not a consensus. One name.
When you can assign rough probabilities and values to outcomes:
EV = Σ (probability of outcome × value of outcome)
Example. Should we pursue this $2M deal?
- 30% chance we close at $2M → +$600K
- 40% chance we close at $1M (discounted) → +$400K
- 30% chance we lose → $0
EV = $1M.
Cost to pursue: ~$150K (sales engineering, exec time). EV/cost = 6.6x. Pursue.
The numbers are rough. The discipline is forcing yourself to actually assign probabilities instead of "it feels like a good opportunity."
From Charlie Munger. Instead of asking "how do we succeed?", ask "how do we guarantee failure?" Then don't do those things. Often easier to generate a list of ways to fail than a list of ways to succeed.
Example. How do we guarantee our product launch fails?
- Launch without doing any customer discovery
- Target a segment we've never sold to
- Don't write positioning before building
- Assume virality
- Don't staff support
Now: are we doing any of those?
When the expected-value math is too noisy to trust. Ask: "In 10 years, which choice will I regret more?" Particularly useful for career + life-scale decisions, but also for bet-the-company moves.
General Jim Mattis's rule: "If you have 70% of the information, go." Waiting for 90% information usually means you've missed the window. 70% + good judgment beats 90% + late every time. For Type 2 decisions especially.
Covered in detail: Pre-mortems. For high-stakes Type 1 decisions, always.
For any meaningful decision, write 1–2 pages before the decision. Template:
The memo goes in the decision log. When you're in the situation six months later wondering "what were we thinking?", this is the answer.
