Building Scenario Frameworks

  • Define three core scenarios: base case (most likely), upside (things go better than expected), and downside (significant headwinds)
  • Each scenario should have internally consistent assumptions: don't just change revenue; adjust CAC, churn, hiring, and timeline accordingly
  • Assign rough probabilities to each scenario (e.g., 60% base, 20% upside, 20% downside) to weight expected outcomes
  • Include a 'survival' scenario: what happens if revenue drops 50%? This reveals your true minimum viable cost structure
