bet-sizing

Size product bets by separating reversible from irreversible decisions and shaping work to fit an appetite. Most product bets are Type 2 decisions — reversible, low-cost to try, high-cost to deliberate. Move fast on those. Save deliberation for Type 1 decisions that are hard to undo.

Type 1 vs Type 2 Decisions (Bezos)

Type 1 (Irreversible): One-way doors. Hard to undo once committed.

  • Choosing a core technology/platform
  • Pricing model changes that affect existing customers
  • Killing a product line
  • Public commitments (partnerships, integrations)

Type 2 (Reversible): Two-way doors. Easy to undo or iterate.

  • Most new features (can ship, measure, remove)
  • UI/UX changes (can A/B test or revert)
  • Internal tooling decisions
  • Most API additions (harder to remove, but additive is safer)

Rule: Use lightweight process for Type 2. Use deliberate process for Type 1. Most product teams over-process Type 2 decisions and under-process Type 1 decisions.
