About consulting
A consulting methodology skill for people structuring business problems, strategy, and transformation work. It emphasizes clarifying the ask, forming an early hypothesis, and applying a small number of relevant frameworks in depth.
Key features
- 01Frameworks for strategy, finance, and operations
- 02Framework combinations matched to problem types
- 03Guidance for analysis and communication
- 04Templates including SWOT and project charter
Use cases
- 01Break down a complex problem into recommendations
- 02Analyze a company, market, or growth options
- 03Plan a project, change effort, or transformation

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:
- 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
/consultor when the user asks for a deep dive. Depth should come from the user's problem, not from the skill. - 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.
- 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.
- 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.
- Show your structure. Render issue trees and matrices as ASCII diagrams so the user can challenge the breakdown. Keep every breakdown MECE.
- Quantify wherever possible. Rough numbers with stated assumptions beat qualitative hand-waving. Sanity-check estimates top-down and bottom-up.
- 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.
- Offer a deliverable. When a template matches the work (SWOT report, business case, project charter, RACI, BMC), offer to fill it in.
