Listen To the Audio:
Every firm calls its people its greatest asset. Far fewer can explain how those people are organized to create value, and that gap is the whole story of the fourth lever.
This is the fourth deep dive in our Enterprise Value Model series. If you missed the introduction from Brian Blaha, start with Five Levers That Separate Firms Building Enterprise Value from Firms Talking About It. The first lever, Top-Line Growth, is here. The second, Margin Expansion, is here. The third, Technology Enablement, is here.
For most of the last few decades, the talent model in professional services was settled. A wide base of staff sat under a small number of partners, staffing ratios were tuned to compliance work that arrived on a calendar, and careers advanced on tenure. It worked because the work was predictable, and the people were plentiful - neither is true anymore.
Three forces are reshaping that model at the same time. First, AI and automation are absorbing the routine work the base used to do. Second, the advisory work replacing it calls for different people, organized differently. Third, the labor market no longer supplies the steady stream of juniors the old pyramid depended on. Firms that treat this as a staffing problem to wait out are managing the wrong thing. How a firm builds and deploys its people is becoming the capability that is hardest for a competitor to copy and the slowest to rebuild once it slips. That is what makes it an enterprise value lever, and why boards and buyers now weigh it as carefully as the numbers.
I have spent my career on the people side of professional services firms, and the pattern is consistent. A talent model, meaning the mix of people, the way they are deployed, and the engine that keeps building their capability, takes years to construct and is felt by every client the firm serves. Firms building real enterprise value have stopped treating talent as something that happens to them and started designing it on purpose. This means looking under the hood and planning for how to keep that engine running well as the work changes.
The Mix is a Design Decision
The first question is composition: who makes up the firm? The strongest firms today carry a deliberately blended workforce: full-time staff plus fractional and contract specialists, onshore teams plus right-shored and offshore delivery, and generalists working next to deep niche experts who earn better economics. That mix is a decision about what work the firm wants to own and what it wants to route elsewhere.
Most firms have never made that decision on purpose. They hire to fill the seat in front of them and end up with a firm shaped by its history instead of its strategy. The test is simple and a little uncomfortable. If you were building the firm today for the work you expect to sell in three years, would you build the team you have now? Where the honest answer is no, that gap is a workforce mix problem the firm has not named yet.
Leverage and Utilization: What the Firm Can Actually Support
Staffing leverage is where the talent model meets the margin lever directly. When more of the work is done by staff instead of partners, the firm converts more revenue into profit, provided the model matches the work. A compliance practice can run a wide leverage base efficiently. Advisory work often cannot, because it sits closer to the partner, resists delegation, and punishes a firm that staffs it like a tax return. As the mix shifts toward advisory, the old leverage ratios stop being a target and start being a trap.
Underneath leverage sits a discipline most firms hold loosely: how many partners the firm can support. Take revenue and margin, then subtract operating costs, the obligations already owed to current and retired partners, and the capital the firm needs to reinvest. What remains is what the firm can genuinely reward and grow. Firms that never run that math end up with a partner group the economics cannot carry, or a base too thin to deliver the work. Investing in top talent competes for the same dollars as an acquisition or a technology build, and the firms that scale treat it as a capital allocation decision they make deliberately.
This is also why growth alone does not fix a talent model. What carried a firm to twenty-five million will not carry it to fifty. Each stage calls for a different shape, with more leaders and ladders, clearer roles, and a deeper bench, and firms that add revenue without evolving the model feel the strain sooner.
Building the Capability, Not Just Buying It
The old apprenticeship model taught people almost by accident. Juniors learned the craft by working through routine engagements under a reviewer, and judgment accumulated over years of repetition. That is precisely the work AI is now absorbing. Take away the bottom rungs of the ladder and the profession loses the very mechanism it relied on to develop its next generation of advisors. Firms that ignore this will wake up in a few years with capable technology and too few people seasoned enough to sit across from a client.
That makes learning and upskilling a deliberate build. It means teaching the skills the routine work used to teach on its own, such as client judgment, commercial instinct, and how to carry an advisory conversation, and doing it on purpose rather than hoping it rubs off. It means career paths built around the work the firm sells today. This is the quiet engine of the whole lever. Done well, it shortens the path from entry to trusted advisor, replacing what repetition once taught slowly with training built for the purpose. The firms that get it right produce a manager who can sit across from a client years earlier than the old ladder would have allowed. A firm that reliably turns good hires into trusted advisors owns something a competitor cannot poach or purchase, and a buyer can tell the difference between a firm that develops its people and one that only employs them.
Talent Model Evolution Is a Design Decision
Workforce mix, leverage and utilization, and the capability engine are three expressions of the same question: did the firm design its talent model, or inherit it? A firm that inherits its model ends up with the team its past produced. A firm that designs it builds the team its strategy requires and builds it before the market forces the issue.
None of this depends on a sale. A firm staying independent needs a talent model that can carry its ambitions without burning out its partners. A firm looking to acquire needs one strong enough to absorb another. And a firm preparing for a transaction will find that talent is one of the first things a serious buyer examines, because it is the hardest thing to fix after the fact. The people were always the asset. What the fourth lever measures is how deliberately the firm chose to build around them.
Next in this series: Governance and Capital Discipline, the fifth and final lever, and why the way a firm makes decisions and allocates capital determines whether the other four levers ever add up to lasting value.
