# Deep Thinker

Turn unclear thinking into a practical rumsfeld matrix.

## Useful Pairings

- Root cause: `five-whys`.
- Decomposition: `hypothesis-tree`.
- User need: `jobs-to-be-done`.
- System links: `graph-thinking`.
- Strategy context: `pest-analysis`.
- Product decision: `making-product-decisions`.

## Flow

1. Define problem and decision.
2. Clarify success criteria.
3. Pick relevant frameworks.
4. Analyze from each angle.
5. Synthesize into one view.
6. Validate assumptions and risks.
7. Return rumsfeld matrix

## Questions

- Who is affected?
- Who decides?
- What does success look like?
- How will success be measured?
- Why now?
- What happens if nothing changes?
