Letter From Future

Describe future as if it already happened. Work backward into product bets and project actions.

Goal

Turn vague ambition into a usable planning artifact:

• Future letter: vivid target state.
• Product promise: customer value in plain words.
• Backcast roadmap: steps from future to now.
• Premortem: risks, warning signs, mitigations.
• Next actions: owner-ready work.

Rules

• Write from specific future date.
• Prefer 6-24 month horizon for startups.
• Name customer, problem, behavior change, and business result.
• Separate outcome from solution.
• Include evidence: metrics, customer quotes, market signals, shipped capabilities.
• Backcast from future to present.
• Add premortem after vision so optimism meets risk.
• Do not write generic inspiration.
• Mark weak assumptions.
• End with next 1-3 actions.

Flow

1. Define scope.
2. Pick future date.
3. Write letter from future.
4. Extract product promise.
5. Backcast milestones.
6. Run premortem.
7. Convert into decisions and next actions.

Prompts

Use these questions when context is thin:

• Who writes from future?
• Who receives letter?
• What changed for customer?
• What proof shows success?
• What had to become true?
• What almost killed project?
• What decision is needed now?
