How Big Consulting Became Dominant‍

For decades, large consulting firms played a central role in corporate decision-making.

Firms like McKinsey, BCG, and Bain built their reputation on three advantages:

• access to information
• structured analytical frameworks
• highly trained generalist teams

For many companies, these firms became the default solution for complex strategic questions.

Executives hired consultants to analyze markets, evaluate options, and recommend strategic directions.

The output was usually a detailed report or presentation outlining the recommended path forward.

In slower-moving industries, this model worked well.

‍

The Environment Has Changed‍

The conditions that supported the traditional consulting model are changing quickly.

Today, information is widely accessible.

Market data, competitive intelligence, and industry analysis are available instantly through digital tools and AI systems.

Companies no longer depend on consulting firms to gather or summarize information.

The real challenge is interpreting signals and translating them into decisions and execution.

That shift changes what companies expect from external expertise.

‍

Slides Are Cheap. Decisions Are Not.

Consulting engagements often produce excellent analysis.

But many companies discover that the hardest part is not understanding the problem. It is actually resolving it.

Strategy decks do not implement themselves.

Teams still need to:

• make decisions
• align departments
• change processes
• execute new strategies

As organizations move faster, companies increasingly prefer operators who can participate in those decisions, not just analyze them.

‍

The Rise of Embedded Expertise‍

Instead of large advisory teams, companies are increasingly bringing in specialized operators for specific mandates.

These operators work inside the company’s decision environment rather than outside it.

For example, when organizations face complex communication challenges during sensitive moments, they often bring in a Strategic Communications Consultant who works directly with leadership to shape messaging, stakeholder communication, and narrative strategy.

The focus is not on producing reports.

It is on helping leadership make clear decisions in high-stakes situations.

‍

Specialization Is Replacing Generalization

Another shift is the increasing specialization of expertise.

Large consulting firms historically relied on generalist teams that could analyze a wide range of industries and problems.

Today many challenges require deep domain expertise.

Examples include:

• AI transformation and platform architecture
• regulatory and compliance complexity
• governance and decision rights
• complex go-to-market systems

Companies increasingly prefer specialists who have directly operated in these environments.

‍

Why the Change Is Happening Quietly

The consulting industry is not disappearing.

Large firms still dominate large enterprise transformations and government projects.

But across startups, growth companies, and many operational challenges, the model is shifting.

Instead of hiring large teams of consultants, companies are experimenting with smaller, more targeted forms of expertise.

The shift is quiet because it happens at the edges first:

• smaller engagements
• specialized mandates
• embedded operators rather than advisory teams

Over time these changes reshape how companies access expertise.

What Replaces the Old Model‍

The emerging model of external expertise looks different.

Companies increasingly combine:

• internal leadership teams
• specialized operators
• structured frameworks for decision-making
• technology platforms that coordinate expertise

The focus shifts from producing analysis to enabling better decisions and faster execution.

This shift is not just about consulting. It reflects a broader change in how organizations access leadership and expertise. As companies move away from large advisory teams toward embedded operators, the boundary between consulting and execution begins to blur. This is closely related to what we explore in Fractional Leadership vs Consulting: What’s the Difference?, where the distinction moves from analysis toward direct involvement in decisions and outcomes.

The future of expertise will not necessarily come from larger advisory firms.

It will come from the ability to install the right judgment exactly where it is needed.
