The next decade will not be a normal cycle.
It will feel like pressure building inside a structure that was never designed to absorb it. Not a sudden shock, but a slow accumulation of forces that no longer cancel each other out. For a long time, the Big 10 operated in a fragile equilibrium. Partnerships controlled ownership. Global networks coordinated delivery. The talent pyramid generated margin. Audit provided trust. Advisory provided growth. The system worked because its contradictions were staggered over time.
That separation is disappearing.
Private equity is entering ownership. Regulators are tightening audit. Clients are demanding global consistency. Delivery is moving across borders. AI is starting to remove work that once justified entire layers of the pyramid. None of these forces is new. What is new is that they are now hitting the system at the same time. And they do not resolve each other. They compound.
Capital demands scale. Scale demands control. Control weakens the partnership model. Delivery centers undermine local economics. AI removes leverage. Audit increases friction. The system is no longer adapting at the edges. It is being forced to reconcile contradictions at its core. That is when structures do not adjust. They break and rebuild.
1. Private equity will become structural
Private equity is no longer experimenting with the industry. It is building positions inside it.
Grant Thornton US brought in New Mountain Capital, alongside CDPQ and OA Private Capital, explicitly positioning the firm for accelerated growth and platform expansion. Baker Tilly went further, combining external capital with large-scale consolidation, culminating in the merger with Moss Adams. These are not isolated transactions. They are early steps in a systematic reconfiguration of ownership. (Cf. The Seven Ways Private Equity Is Breaking Into the Big 10)
What changes first is not the capital structure. It is the logic of the firm.
Partnerships optimize for annual partner income, negotiated autonomy, and internal alignment. Private equity introduces a different discipline: integration, scalability, acquisition pipelines, and ultimately exit. That logic does not stay contained within one geography or one deal. Once capital enters, it forces the firm to behave like an asset. Decisions start to reflect not only internal priorities, but external expectations about growth, valuation, and liquidity.
This is where the tension becomes irreversible.
You cannot run part of the firm on partnership logic and another part on capital logic without consequences. The question is no longer how to optimize this year’s distribution. It becomes what kind of asset this firm is turning into and who it is ultimately being built for. And unlike entry, which the industry has now learned to manage, exit will expose whether this model actually holds together. (Cf. The Exit Problem – Private Equity Has Found Ways Into Professional Services, Getting Out Is Harder)
2. Networks will split into two-speed firms
As private capital enters professional services selectively, the traditional global network model does not simply evolve. Increasingly, it begins to diverge internally.
You can already see the pattern emerging across the industry. Baker Tilly operates with a capital-backed US platform while other member firms remain anchored in traditional partnership structures. Grant Thornton shows similar dynamics. Some parts of the network gain access to larger pools of capital, faster acquisition capability, deeper technology investment, and more centralized operating models, while other member firms continue operating under local partnership economics and more constrained governance structures. The brand remains global, but the underlying economics increasingly do not. (Cf. Case Study: Baker Tilly and Private Equity, Case Study: The Fragmentation of Grant Thornton)
This increasingly resembles what I described later in The Two-Speed Firm: the gradual emergence of multiple economic and operating realities inside the same professional-services organization.
One side of the firm becomes faster, more integrated, more technology-driven, and more aggressive in deploying capital. The other remains slower, negotiated, locally governed, and structurally tied to traditional partnership economics. That divergence does not remain abstract. It increasingly appears in investment capacity, operating models, talent migration, platform adoption, and ultimately in how clients experience the organization itself. The idea of “one firm” begins weakening long before any formal separation occurs. (Cf. Case Study 31: BDO’s Third Way, Case Study: Forvis Mazars – One Brand, Two Firms)
At that point, coherence increasingly becomes performative. Firms continue speaking the language of global integration while internally managing structurally different economic systems, governance models, and investment realities. That is a fundamentally different organization from the classic professional-services partnership model — and significantly harder to govern over time.
3. Breakups will be messy and continuous
The obvious response to these tensions is separation.
But the industry has already shown how hard that is to execute. EY’s attempt to split its audit and advisory businesses under Project Everest did not fail because the logic was wrong. It failed because the system could not align behind it. The economics pointed one way. Governance blocked it. That gap is not an exception. It is the pattern. (Cf. Case Study: The Failed EY Split – Project Everest)
The consequence is not that breakups stop.
They become fragmented, partial, and continuous. Instead of one defining transaction, firms move through a sequence of carve-outs, local restructurings, alternative ownership models, and incremental decoupling. Each step looks tactical. Taken together, they amount to structural change. The integrated firm does not break in one moment. It unwinds over time. (Financial Times – “KPMG sells restructuring arm to HIG Capital, creating Interpath Advisory”,
Reuters – “PwC sells global mobility business to Clayton, Dubilier & Rice, creating Vialto Partners”)
This is harder to manage than a clean split.
Because it never creates clarity. The firm remains in between states. Part integrated, part separated. Part aligned, part conflicted. And in that state, decision-making slows, accountability blurs, and transformation risk increases. The system does not collapse. It drifts into something less coherent and more difficult to control.
4. Audit will be pushed into its own economic logic
Audit is no longer just another service line. It is becoming a structural constraint.
The consequences of failure do not disappear. They accumulate. Cases like EY and Wirecard continue to shape regulatory pressure years after the underlying events. Fines, bans, litigation, and reputational damage do not hit once. They linger. Audit carries long-tail risk in a way that no other part of the firm does. And that risk is becoming harder to absorb within the same economic model as high-growth advisory businesses. (Reuters – “EY fined and banned over Wirecard audit failures”, BaFin – Wirecard enforcement actions, Financial Times – Wirecard coverage)
At the same time, the rest of the firm is being pushed in the opposite direction.
Consulting and advisory require capital, speed, and flexibility. They depend on scaling delivery, investing in platforms, and moving quickly into new areas. Audit requires control, independence, and risk containment. These are not compatible logics. They can coexist for a period of time. But as pressure increases, the question becomes unavoidable: not whether audit is important, but whether it fits the economic model of the rest of the firm.
That is the contradiction that made Everest both necessary and impossible.
5. Delivery centers will become power centers
The shift to global delivery is no longer about cost. It is about where the firm actually operates.
Firms are expanding aggressively in locations like India, not as an auxiliary capability, but as a structural response to talent shortages and cost pressure in core markets. What starts as capacity expansion quickly becomes capability concentration. Process knowledge, system expertise, and operational control begin to accumulate where the work is actually done, not where the client relationship sits. (Reuters – “US accounting firms expand in India amid talent shortage”, AICPA – Workforce trends report)
This changes the internal balance of power.
For decades, authority followed proximity to the client. Partners in local markets controlled relationships, revenue, and decision-making. Delivery centers were support functions. That hierarchy is starting to invert. When execution, data, and systems are concentrated in global delivery hubs, those hubs become critical to how the firm functions. Control does not formally move, but it shifts in practice. (McKinsey – Global delivery and offshoring insights, Deloitte Insights – Global business services)
Over time, many of these delivery environments increasingly evolve beyond simple support functions into globally integrated operational infrastructures with centralized workflows, shared technology environments, standardized processes, platform teams, and increasingly AI-enabled delivery capabilities. I explored these operational dynamics further in The Silent Engine: How Global Delivery Centers Are Rewiring Professional Services Firms.
The firm continues to present a local face.
But the engine is elsewhere. And over time, that gap becomes impossible to ignore.
6. Talent will split into a barbell
The traditional talent pyramid is no longer economically stable.
It worked because the work required it. Large teams executed, reviewed, coordinated, and learned in a structured progression. That model assumed a steady flow of tasks that justified each layer. That assumption is breaking. Work at the lower end is moving into delivery centers or being standardized. Work at the higher end is concentrating in a smaller group of individuals who combine client access, judgment, and technological fluency. (McKinsey – “Generative AI and the future of work”, Goldman Sachs – “AI could replace 300 million jobs”, Financial Times – consulting workforce changes)
What disappears is the middle.
Roles that once connected strategy and execution become harder to justify. They are too expensive to scale and too standardized to differentiate. AI accelerates this shift by removing parts of the work that previously sustained those layers. The result is not a clean redesign. It is an uneven structure. A smaller top. A broader base. And a hollowing middle.
Firms will continue to talk about career progression as if the pyramid still exists.
Internally, the model will have already moved on.
7. Margin will move from leverage to platforms
The economic model of the industry is shifting underneath the organization.
For decades, margin came from leverage. More people meant more output, and with the right utilization, more profit. That logic depends on work scaling with headcount. Once parts of that work are automated, standardized, or relocated, the relationship breaks. Adding people no longer guarantees better economics. In some cases, it reduces them.
Firms are already searching for alternatives.
Platform-based offerings, repeatable workflows, and managed services are early signals of a different model. Big Four’s platform initiatives and repositioning around AI are not incremental adjustments. They are attempts to move margin away from people and into systems. That shift requires different capabilities, different governance, and a different way of running the firm. (Cf. The Professional Services AI Paradox: How the AI Platform Economy Is Colliding with the Partnership Model)
This is where many firms will struggle.
Because you cannot build a platform business on top of a structure designed for leverage without changing that structure.
8. Member firm autonomy will erode
The member firm model is reaching its limits.
It worked when most work was local, systems were fragmented, and coordination requirements were manageable. That environment no longer exists. Clients expect consistency across borders. Delivery spans multiple locations. Technology platforms require integration. Capital, once introduced, does not respect national boundaries.(Accountancy Europe – “The Future of the Audit Profession”, Financial Times – “Big Four accounting firms rethink global structures”)
Autonomy becomes conditional.
Decisions that were once local begin to move upward, formally or informally. Moves like cross-border mergers are visible expressions of this shift, but the deeper change is less explicit. Local firms retain legal independence, but lose practical control over key decisions. Standards tighten. Exceptions become harder to justify. Alignment becomes less negotiable. (Reuters – “PwC restructures consulting operations amid slowdown”)
This does not happen overnight.
But over time, the balance shifts. And once it does, the original logic of the network begins to fade.
9. Regional clustering will accelerate
As autonomy erodes, consolidation becomes the logical next step.
The cost of staying competitive has increased. Technology platforms, compliance requirements, and delivery models require scale. Smaller units struggle to carry that burden independently. Regional clustering offers a way to share investment, reduce duplication, and increase control. (Reuters – “KPMG firms in UK and Switzerland agree to merge”, Accountancy Europe – “The Future of the Audit Profession”)
This changes more than cost structures.
It reshapes governance. Fewer units mean fewer decision points. Large-scale changes become easier to implement. But influence shifts as well. Local leadership gives way to regional structures. Power concentrates. The system becomes more manageable, but also more centralized. (Financial Times – “Big Four firms explore restructuring to cope with global pressures”, Reuters – “Accounting firms rethink global structures amid regulatory and cost pressures”)
This is not just optimization.
It is a redefinition of how the firm is organized.
10. The mid-tier will be reshaped
Pressure at the top does not stay at the top.
The mid-tier has relied on a model that combines partner economics with incremental growth. That model is now under strain. Rising costs, technology investment requirements, and changing client expectations are eroding margins. At the same time, capital-backed platforms are entering the same space with different economics and a different speed of execution. (Consultancy.uk – “BDO to reduce senior partners, clearing path for younger staff”, Reuters – “Baker Tilly, Moss Adams to merge in $7 billion deal”)
The result is a narrowing set of viable positions.
Some firms consolidate to gain scale. Others are acquired. Some retreat into niches where differentiation is still possible. What disappears is the idea of a stable middle. The label “mid-tier” remains, but it describes firms moving in fundamentally different directions under the same pressure.
This is not a cycle.
It is a sorting process.
11. Expansion into adjacent services will accelerate
Growth will increasingly come from areas that fit the emerging operating model.
The move into adjacent services is not new. What changes is the selection logic. Firms are no longer expanding simply to broaden capabilities. They are expanding into areas that can be standardized, integrated, and scaled. Legal is one example, particularly where regulatory changes allow new ownership structures. But the pattern extends beyond any single domain. (Financial Times – “Big Four accounting firms push into legal services”, Legal Business – “The Big Four’s global legal ambitions”)
The common denominator is structure.
Work that can be systematized and embedded into platforms becomes attractive. Work that depends entirely on individual expertise becomes harder to scale. Firms are not just asking where they can grow. They are asking where growth fits the model they are trying to build.
That is a different kind of expansion.
More selective. More constrained. And more structural.
12. Boards will become real governance bodies
All of these shifts converge at the top.
Governance structures were designed for partnerships operating in a relatively stable environment, where most decisions were local and change was incremental. That environment is gone. Cross-border delivery, capital involvement, platform economics, and structural transformation create a level of complexity that those governance models were not designed to handle.
The gap becomes visible when decisions stall.
When initiatives like Project Everest fail, it is not because the underlying logic is unclear. It is because the system cannot align around it. Governance becomes the bottleneck. Not in form, but in function. Boards review, discuss, and align, but struggle to drive decisions that cut across the core tensions of the firm.
This is where the role of the board changes.
Oversight is no longer enough. Understanding how the system behaves becomes critical. Not just what is happening, but why it is happening, and where it is likely to break next.
Most boards are not set up for that yet.
Closing Thoughts
What makes this moment different is not any single force in isolation.
Private equity alone would not fundamentally reshape the industry. Neither would AI, delivery industrialization, audit pressure, platform economics, or operating-model consolidation on their own. What matters is the way these forces increasingly interact with and reinforce one another.
Private equity changes ownership expectations. Ownership pressures drive integration. Integration strains the traditional network model. Delivery shifts toward centralized platforms and global infrastructure. The talent pyramid stretches and gradually changes shape. Margin moves away from classic leverage economics toward operational scale, technology, and platform control. Audit becomes harder to sustain economically within the same structures. Governance systems designed for a different era struggle to coordinate increasingly industrialized organizations.
For a long time, many of these tensions could still be absorbed because they remained relatively separated. Different parts of the firm carried different pressures at different times. Local autonomy offset centralized friction. Growth masked inefficiency. Partnership economics delayed harder structural decisions.
That separation is becoming more difficult to maintain.
The pressures increasingly converge inside the same organizations, often simultaneously. And when they converge, firms do not simply adjust incrementally at the margins. The underlying shape of the system itself gradually starts changing.
That transition will not be linear or uniform. Different firms will move at different speeds. Some tensions will remain manageable for years. Others may surface unexpectedly through failed transformations, governance conflict, talent fragmentation, operational dependency, or economic strain.
Much of this change may remain difficult to see from the outside for quite some time.
But the direction of travel increasingly appears structural rather than cyclical.
What This Means for Boards
Boards tend to look for trends they can monitor and manage.
That assumes change is gradual, predictable, and accompanied by relatively clear intervention points. The current environment inside professional-services firms is more complex. The key questions are no longer whether private equity enters the industry, whether AI changes delivery models, or whether audit economics become increasingly constrained. Many of these shifts are already underway. The more important question is where the different economic, technological, governance, and operating logics inside the firm gradually stop aligning with one another.
That is where strain starts accumulating inside the system.
Professional-services firms rarely struggle because of one isolated external disruption alone. More often, tensions build internally over time. Capital requirements pull in one direction. Governance structures support another. Client expectations evolve differently. Technology changes delivery economics faster than organizational models adapt. The result is often not one dramatic breaking point, but a growing disconnect between how the firm operates, how it creates value, and how it governs itself.
The role of boards is therefore changing whether firms explicitly acknowledge it or not.
It is no longer sufficient to oversee performance metrics or approve transformation initiatives in isolation. Boards increasingly need to understand how the underlying system behaves as a whole: where incentives conflict, where operational dependency accumulates, where governance structures lag behind economic reality, and where transformation efforts may become structurally difficult to execute.
That requires a different perspective. Less focus on individual initiatives in isolation. More focus on the interaction between governance, economics, technology, operating models, and organizational behavior over time.
I work with boards and executive teams on independent perspectives across professional-services transformation, governance, operating models, platform economics, and large technology programs. If your leadership team is working through similar structural questions, feel free to reach out.
