mckinsey-consultant
McKinsey-level structured consulting methodology for strategy, analysis, and problem-solving. This is the analytical OS — load it for any strategy work, investment evaluation, structured diagnosis, framework design, or McKinsey-style document. It owns all analytical methodology: 7-step MBB problem solving, MECE issue trees, 7 strategy dimensions, Pyramid Principle, Six Screening Questions for investments, and all analytical modules (Porter's, SWOT, market sizing, positioning maps, value chain). It does NOT govern evidence gathering or source validation — that is market-research's job. For any task that requires original data collection (market sizing, competitive intelligence, customer research), invoke market-research on top of this skill. For financial modeling, use financial-model-builder. For PPTX/docx output, use pattern-investment-pptx or pattern-docx.
