Management Consultant in 2026: Decks at the Speed of Thought

McKinsey Lilli, Gamma, and Claude generate first-draft slides and research in minutes. The real consulting work — client relationships and implementation — is more human than ever.

36 min · Reviewed 2026

Ana is a senior associate at a top-three firm on a growth strategy engagement. At 10 p.m. the team's planning meeting wraps. She types the hypothesis tree into Lilli, which pulls internal McKinsey IP, relevant public research, and historical case data. Gamma drafts 30 slides by midnight. Ana and her manager rework 15 of them from scratch because the story is wrong. The AI saved 20 hours of production work; the 4 hours of 'is the story right?' are still the work.

What AI touches

Research — internal KM search + public research synthesis.
Slide generation — Gamma, Tome, Beautiful.ai, Pitch AI build decks from outlines.
Data analysis — AI writes Python/SQL and generates chart drafts.
Interview synthesis — Otter + AI transcribes and themes stakeholder interviews.
Model building — financial models drafted faster.
Client meeting prep — AI briefs you on attendees and their likely questions.
Implementation planning — AI templates project plans and RACI.

The specialized tools

McKinsey Lilli — McKinsey's internal AI assistant, deeply integrated with KM.
BCG's gAI / KT — BCG's competing internal platform.
Deloitte's Zora AI, PwC's ChatPwC — Big Four stacks.
Gamma, Tome, Pitch — external AI presentation builders.
Beautiful.ai — slide design automation.
Claude and NotebookLM — external workhorses for research.
Mural and Miro with AI — workshop facilitation.

Task	Before AI (2020)	Now (2026)
First-draft deck	2-3 days of junior time.	4 hours with AI + partner direction.
Industry scan	Week of reading.	1 day with AI synthesis + verification.
Interview transcription	Outsourced; 48-hour turnaround.	Real-time with AI themes.
Implementation plan	Template + consultant work.	AI templated; customized.
Proposal writing	Days of drafting.	Draft overnight; partner edits.

What still takes a human

The client relationship. The trust that lets a CEO tell you the real problem, not the polished one. Workshop facilitation when two executives disagree in the room. The judgment to push back on a partner's hypothesis. Writing the executive summary that a CEO will actually read. Implementation — being on the ground with a client's team when a strategy meets reality. Honesty when a project is failing. Consulting is still, stubbornly, a relationship business.

Your skill path

Structured problem solving — hypothesis trees, MECE, issue trees.
Storytelling — pyramid principle, slide architecture.
Excel modeling — financial and operational.
Client communication — listening, reading the room, executive presence.
One industry or functional specialty — strategy, ops, tech, M&A, PI.
AI workflow — the consultant who generates better first drafts is promoted faster.

If you want to be a consultant: In high school, debate and student government matter more than you think. In college, top-tier GPA at a target school is the default path to MBB (McKinsey, BCG, Bain) and Big Four strategy. Major does not matter; grades do. Case interview prep is its own skill — practice 50+ cases before on-campus recruiting. Consulting compensates well, runs hard, and has high turnover (many leave for corporate strategy or industry). AI has made the hours better and the juniors fewer. The survivors in 2026 are client-ready within two years.
