Management Consulting

매 한 줄

"매 management consulting 은 hypothesis-driven problem solving as a service". McKinsey/BCG/Bain (MBB) 의 1960s codification — pyramid principle, MECE, issue tree, hypothesis-driven 의 four pillars. 매 2026 modern state: AI augmentation (Claude Opus 4.7, GPT-5) 으로 research/synthesis 의 80% acceleration, but human judgment + executive trust 가 still core.

매 핵심

매 four pillars

  • Pyramid principle (Minto): top answer first, supporting reasons next, evidence below.
  • MECE: Mutually Exclusive, Collectively Exhaustive — partition framework.
  • Issue tree: top question → sub-questions, recursively.
  • Hypothesis-driven: form answer first, test against data — not bottom-up boil-the-ocean.

매 typical engagement structure

  • Week 1-2: scoping, interviews, hypothesis tree.
  • Week 3-6: data gathering, model building, expert calls.
  • Week 7-9: synthesis, slide drafting, partner reviews.
  • Week 10-12: client workshops, final readout, implementation roadmap.

매 modern (2026) augmentation

  • AI research: Claude/GPT for industry primers, expert call prep, public filings synthesis.
  • AI modeling: code-interpreter for forecasts, sensitivity tables.
  • AI slide drafting: rough layout from issue tree + key numbers; human polish.
  • Still human: client relationship, executive trust, judgment under ambiguity, internal politics navigation.

매 firm tiers

  1. MBB: McKinsey, BCG, Bain.
  2. Tier 2: Strategy&, Oliver Wyman, LEK, Roland Berger, Kearney.
  3. Big 4 strategy: Deloitte Monitor, EY-Parthenon, PwC Strategy&, KPMG.
  4. Boutique: Veritas, Putnam, Analysis Group (specialized).

💻 패턴

Issue tree as data

interface IssueNode {
  question: string;
  hypothesis?: string;
  children: IssueNode[];
  evidence: Evidence[];
  status: "open" | "supported" | "refuted";
}
function leaves(node: IssueNode): IssueNode[] {
  return node.children.length === 0 ? [node] : node.children.flatMap(leaves);
}

MECE check

function isMECE<T>(partition: T[][], universe: Set<T>): { mutually: boolean; exhaustive: boolean } {
  const flat = partition.flat();
  const mutually = flat.length === new Set(flat).size;
  const exhaustive = [...universe].every((x) => flat.includes(x));
  return { mutually, exhaustive };
}

Expert call synthesis prompt (Claude Opus 4.7)

const prompt = `
You are a research analyst. Given these 5 expert call transcripts on [TOPIC],
extract:
1. Areas of consensus (≥3 experts agree)
2. Areas of disagreement
3. Quantitative anchors (market size, growth, margin)
4. Open questions for further research
Output as MECE bullets, max 300 words.
`;

|              | High Impact | Low Impact |
|--------------|-------------|------------|
| Easy to do   | DO NOW      | Quick wins |
| Hard to do   | Strategic   | DROP       |

매 결정 기준

상황 Approach
C-suite strategy refresh MBB or Tier 2 strategy boutique
Operational turnaround Big 4 + ops specialists (AlixPartners)
M&A due diligence Bain (PE focus), strategy boutiques
Digital/AI transformation McKinsey QuantumBlack, BCG X, Bain Vector
In-house build Hire ex-consultant + AI tooling

기본값: Hypothesis-driven + issue tree + MBB-style synthesis. AI augmentation for research/modeling. Human for trust/judgment.

🔗 Graph

🤖 LLM 활용

언제: industry primer, expert call prep, slide drafting, financial modeling, synthesis. 언제 X: client relationship building, executive trust, internal politics, judgment calls under deep ambiguity.

안티패턴

  • Boil the ocean: hypothesis 없이 모든 data 모음 → time/budget overrun.
  • Pretty slides, weak answer: aesthetics > insight 의 trap.
  • Recommendation without data: "we believe" without grounding.
  • AI hallucination unchecked: AI 의 fabricated stats 의 client-facing slide 의 disaster.

🧪 검증 / 중복

  • Verified (Minto's Pyramid Principle, McKinsey/BCG/Bain public materials, 2026 industry observation).
  • 신뢰도 A.
