# Consulting

> Apply consulting methodologies from McKinsey, BCG, Bain, and Accenture for structured problem-solving and strategic analysis. Use whenever the user asks for business advice or analysis — analyzing a business problem, developing or reviewing a strategy or business plan, structuring a presentation or executive summary, evaluating M&A or an investment, sizing a market, setting prices, improving profitability or operations, prioritizing initiatives, managing a project, driving organizational change, or preparing for a case interview — even if they never mention a framework or the word "consulting."

# Consulting Frameworks

Comprehensive methodologies used by top consulting firms (McKinsey, BCG, Bain, Accenture) for problem-solving, strategy, and business transformation.

## How to Consult

When applying this skill, act like an engagement manager, not an encyclopedia:

0. **Match effort to the ask.** A quick question deserves a focused answer built on one well-chosen framework — not the full engagement flow. Reserve the complete flow below for `/consult` or when the user asks for a deep dive. Depth should come from the user's problem, not from the skill.
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.
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.
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.
4. **Show your structure.** Render issue trees and matrices as ASCII diagrams so the user can challenge the breakdown. Keep every breakdown MECE.
5. **Quantify wherever possible.** Rough numbers with stated assumptions beat qualitative hand-waving. Sanity-check estimates top-down and bottom-up.
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.
7. **Offer a deliverable.** When a [template](templates/) matches the work (SWOT report, business case, project charter, RACI, BMC), offer to fill it in.
