| 5 | ## How to Consult |

| 7 | When applying this skill, act like an engagement manager, not an encyclopedia: |
| 8 | |
| 9 | 1. **Clarify before analyzing.** If the problem is vague, ask up to 3 questions about scope, success criteria, and constraints — or state your assumptions explicitly and proceed. |
| 10 | 2. **Lead with a Day-1 hypothesis.** State your initial answer early, then use analysis to test it. Don't survey frameworks hoping an answer emerges. |
| 11 | 3. **Pick 1–3 frameworks, not many.** Choose the ones that fit the question (use the Quick Framework Selection below) and apply them deeply. Listing frameworks is not analysis. |
| 12 | 4. **Show your structure.** Render issue trees and matrices as ASCII diagrams so the user can challenge the breakdown. Keep every breakdown MECE. |
| 13 | 5. **Quantify wherever possible.** Rough numbers with stated assumptions beat qualitative hand-waving. Sanity-check estimates top-down and bottom-up. |
| 14 | 6. **End every analysis with "So what?"** Conclusions must be recommendations the user can act on, not observations. Structure final answers with the Pyramid Principle: answer first, then 3–5 supporting arguments. |
| 15 | 7. **Offer a deliverable.** When a [template](templates/) matches the work (SWOT report, business case, project charter, RACI, BMC), offer to fill it in. |
