What happens when the world’s most famous consulting firm quietly admits the pyramid is no longer enough?
In a recent Harvard Business Review interview, Bob Sternfels, Global Managing Director of McKinsey & Company, marked the firm’s 100th anniversary with something more than celebration. He described a structural rewrite of consulting itself.
This wasn’t nostalgia. It was a declaration of reinvention.
And it matters.
- The Rise of the Agentic Workforce
McKinsey today reportedly operates with 40,000 humans and 20,000 AI agents—with a predicted 1:1 ratio within 18 months.
Let that sink in.
This isn’t “automation.” It’s human-agent collaboration at scale.
AI agents now handle:
- Linear analysis
- Data-heavy synthesis
- Pattern inference
- Repeatable workflows
Humans increasingly handle:
- Framing the right problem
- Context interpretation
- Navigating political and cultural nuance
- Making judgment calls under uncertainty
The consulting pyramid—junior analysts grinding PowerPoint decks beneath senior partners—is evolving into something flatter, faster, and hybrid.
This shift reflects what we see across the market: the value is no longer in producing slides. It’s in producing momentum.
- From Billing Hours to Underwriting Outcomes
One of Sternfels’ most revealing comments: Roughly one-third of McKinsey’s revenue now comes from underwriting outcomes.
Translation?
Consultants are no longer paid only for advice. They are increasingly tying their compensation to measurable client impact.
Instead of:
“Here’s your strategy deck.”
It becomes:
“Here’s the business case. We succeed when you succeed.”
That alignment changes everything:
- Incentives
- Risk distribution
- Accountability
- Depth of involvement
It also signals the commoditization of analysis. When AI can produce competent analysis instantly, the premium shifts to implementation, orchestration, and measurable value creation.
This is not the end of consulting. It is the end of advisory without accountability.
- AI Success Is 50% Organizational Rewiring
Perhaps the most important takeaway for CEOs:
AI transformation is not primarily a technology challenge.
It’s an organizational one.
Sternfels notes that more than half of successful AI impact comes from rewiring the organization:
- Flattening management layers
- Breaking functional silos
- Redesigning workflows
- Removing human gatekeeping from processes
In traditional environments—banking mortgage flows are a classic example—work moves through rigid departmental checkpoints. AI exposes how much of that flow is procedural friction rather than value creation.
The real bottleneck isn’t the model.
It’s the org chart.
(We consistently see this in South African enterprises as well—technology pilots succeed, but institutional inertia stalls scaling.)
- What Humans Must Now Be Great At
If AI dominates inference and linear reasoning, what remains durable?
Sternfels outlines three human pillars:
- Aspiration
AI cannot set ambition. It cannot decide how bold your company should be.
Vision is still human.
- Judgment
Models predict patterns. They do not understand truth, ethics, or consequences.
Humans must impose values.
- Novel Thinking
AI is exceptional at “the next logical step.” It is less reliable at discontinuous leaps.
Breakthrough innovation—non-linear, creative, counterintuitive—still belongs to human imagination.
This reframes professional development entirely. The premium skill of the next decade isn’t technical coding.
It’s:
- Learning agility
- Context framing
- Cross-disciplinary synthesis
- Ethical reasoning
- Offense and Defense in an Age of Continuous Shock
Modern leadership now requires duality.
Sternfels describes a CEO’s role as simultaneously:
- Defense: Build buffers, resilience, shock absorption.
- Offense: Make bold bets even amid volatility.
In a world of geopolitical shocks, regulatory shifts, and exponential AI progress, resilience is not passive stability. It is adaptive strength.
The firms that survive will:
- Maintain financial slack
- Invest during downturns
- Experiment faster than competitors
- Avoid institutional brittleness
Resilience becomes strategic leverage.
- Accountability and Professional Standards
After past controversies, McKinsey is evolving its client selection and governance framework to standards comparable to public companies.
This signals something larger:
As AI scales impact, the ethical weight of advisory work increases.
When consultants and AI agents influence:
- Climate transitions
- Financial systems
- Public health
- Workforce restructuring
Professional accountability becomes non-negotiable.
Technology amplifies consequences.
Humility and courage—Sternfels’ phrase—are no longer soft virtues. They are operating principles.
What This Means for the Imbila Community
McKinsey represents the top-down reinvention of global consulting.
Imbila represents something complementary:
The distributed empowerment of builders, independents, and underdogs.
Where large firms industrialize agentic capability at scale, smaller firms and independent consultants now have access to the same intelligence layer.
The moat is no longer information. It’s orchestration.
The age of AI shifts advantage toward those who can:
- Architect context
- Integrate agents into real workflows
- Align incentives with outcomes
- Drive change inside messy human systems
The consulting pyramid is dissolving.
What replaces it is not flat chaos. It’s a network of humans and agents co-creating impact.
The Bigger Question
If even McKinsey & Company is rewriting its model at 100 years old…
What should the rest of us be rethinking?
This moment is less about technology and more about identity.
Are you:
- An advisor?
- A slide producer?
- A system rewiring partner?
- An outcome underwriter?
The next decade will reward the latter.

Final Reflection
AI is not eliminating consulting.
It is eliminating consulting that does not produce measurable change.
If the pyramid is being dismantled, the opportunity is not to defend it.
It is to design what comes next.
