The Consultancy Challenge: How Should McKinsey Invest in AI?

The consulting world is confronting a monumental change, as industry leaders like McKinsey & Company reassess their strategies amidst the AI revolution.
McKinsey & Company is among those at the helm of this change.
Known for providing strategic advice to Fortune 500 companies, the company is now embracing AI to redefine its consulting services as it faces 2025 with an evolution driven by AI.
The advent of AI challenges the foundational aspects of traditional consulting.
AI’s capability to generate the same high-quality presentations and data analyses once offered by consultants – achieving in moments what used to take months – has prompted McKinsey to reinvent itself.
This evolution is essential for sustaining their position in a US$1tn global market facing a potential overhaul.
What happens when AI disrupts traditional consulting
Kate Smaje, the Senior Partner spearheading McKinsey’s AI push, acknowledges the existential threats posed to the consulting profession by AI advancements, saying, “Do I think that this is existential for our profession? Yes, I do.”
The significant reduction in required power, coupled with AI’s efficiency, has led McKinsey to reduce its human workforce from 45,000 to 40,000 while simultaneously integrating around 12,000 AI agents.
Bob Sternfels, McKinsey’s Global Managing Partner, sees AI as a natural extension of the company’s evolution.
He envisions a future where McKinsey runs seamlessly with an AI agent for every human employee, reflecting a bold commitment to marrying technology with consultancy.
Inside AI-driven consulting innovations
The infusion of AI into McKinsey’s operations has transformed their consulting methodology. AI-driven bots now assist in:
- Creating detailed presentations quickly
- Capturing comprehensive meeting notes
- Condensing extensive research into actionable insights
- Upholding McKinsey’s distinct communication clarity
- Ensuring logical coherence in strategic recommendations
AI’s tools have given rise to efficiencies that allow project teams to reduce personnel from fourteen to just two or three consultants, supported by AI models.
This drastic transformation signifies a redefined value proposition in delivering client services.
The transformation extends far beyond internal efficiency gains. McKinsey has recognised that clients no longer want “a suit with PowerPoint”, as Nick Studer, CEO of Oliver Wyman puts it.
The importance of the human element
McKinsey’s reinvention extends to addressing emergent market demands.
Clients increasingly prioritise hands-on implementation over mere strategic advisories.
In response, McKinsey has pivoted to incorporate technology solutions into its service offerings, now constituting 40% of the firm’s revenue.
A quarter of McKinsey’s service arrangements have shifted towards outcome-based compensation models, aligning their profitability with successful client outcomes rather than time-based billings – reflecting a broader trend towards valuing tangible results over traditional deliverables.
Despite the extensive AI adoption, McKinsey continues its focus on human capital, with a strategic emphasis on hiring.
The priority now is identifying unique human skills that complement AI’s efficiency. Bob highlights, “You can get to a pretty good, average answer using the technology now,” recognising that while AI replaces baseline expertise, complex, nuanced understanding remains superiorly human.
McKinsey values seasoned partners for their experienced intuition in navigating complexities that AI cannot address, showing strategic hires of adaptive, communicative and collaborative individuals.
