The Leverage Model Used to Run on Attrition. Now It Runs on Math.

Ten years ago I understood my career in accounting the way most people did, as a pyramid. There were a lot of associates, fewer seniors than that, fewer managers than seniors, and a handful of partners sitting on top of all of it, and everyone knew the shape because the shape had been the same for decades. You put in your reps as an associate, you learned to review the reps of the associate behind you as a senior, and by the time you made manager you were expected to run a team that looked a lot like the team that trained you. The pyramid had a rhyme and a reason to it, and the rhyme was attrition. Firms hired more associates than they needed at senior level because they knew a chunk of that class would leave before they got there, so the math worked out on its own.

That math doesn't work the same way anymore, and I think most students and early career professionals are hearing pieces of this story without ever getting the full picture of what changed and why it matters for their own career.

Start with what happened at the bottom of the pyramid. Ten years ago, auditing a Fortune 500 company meant putting ten associates in a conference room in the middle of a city, splitting the sections up so half the room worked cash and half worked accounts payable, and grinding through twelve hour days together for weeks. Now a lot of that same work runs through a center of excellence a few hundred or a few thousand miles away, and the domestic team shrinks down to the seniors who review it. A colleague of mine at a Big Four firm described exactly this shift on their own engagements. The titles on the org chart still say associate and senior, but the room that used to hold ten people now holds two or three, because the work that used to justify the other seven now happens somewhere else.

Here is where it gets interesting for someone trying to figure out their own career, because the old model assumed a wave of associates would burn out or leave before hitting senior, and that attrition is what created room for the people who stayed to move up. If offshore has already absorbed a chunk of the associate layer, firms cannot afford the same attrition rate at senior anymore because there is no deep bench underneath refilling the gap. The bottom two layers of the pyramid are shifting from an attrition based model to something closer to one for one. Fewer people come in, and firms need almost all of them to make it through if they want a senior class at all.

I run a consulting firm that never had the traditional pyramid to begin with, so I feel a different version of this problem. Our clients pay for a level of experience and judgment that an entry level hire cannot provide, so we have never hired at that level, and it was never really a choice we made in reaction to AI or offshore work. But we still feel the ripple effect, because we hire senior talent from public accounting firms that are now producing fewer senior associates. Ten years ago I would get a wave of resumes from associates who had just made senior and were ready to leave for something new. That wave has thinned out for two reasons I can point to directly. Fewer associates are coming through the pipeline in the first place, so there is less forced burnout pushing people toward the door. And public accounting has raised its own pay enough in recent years that leaving for outside opportunities does not carry the pay and title jump it used to, so even the people who might have left ten years ago are more likely to stay put.

I have caught myself saying something in the last few weeks that I never expected to say ten years ago, which is that I can no longer predicate someone's promotion to manager purely on whether they delegate work to the people below them, because in some cases we do not employ enough people below them to make that a real test. That same conversation is happening inside public accounting firms too, just for a different reason. Delegation hasn't disappeared so much as it has moved sideways, going to an offshore team or an AI tool instead of down to an associate, and the review skill underneath it still matters just as much as it always did. What isn't guaranteed anymore is the proof point that used to come with it, the idea that managing a room full of junior staff is something everyone coming up gets a chance to do on the way to senior.

None of this changes what gets someone promoted, and I want to be direct about that because I do not want this to read as a warning that the ladder is broken. An associate still has to learn how the work gets done and why it gets done that way before any of it becomes automatic, and a senior still has to pull quality work out of resources they did not personally touch, whether that resource sits three desks away or three time zones away, and a manager still has to take whatever mix of people and tools they are handed and turn it into an engagement that runs on time and on budget. What changed is what sits inside that mix, and pulling good output out of a person, an offshore team, or an AI tool is the same skill wearing a different outfit.

If you are a student or early career professional reading this, the advice is not that different from what it was ten years ago. Get to senior and manager as fast as you responsibly can, because those titles still carry the leverage and the compensation that make this career worth it. But understand that the reps you are building along the way might look different than the reps your manager built, and that is fine as long as you are building the underlying skill of directing work you did not do yourself toward a result someone is paying for. The pyramid still exists, but it is being built by fewer hands than it used to be, and if you are one of those hands, your job is to prove you can get real work out of whoever or whatever ends up standing next to you. That is what has always separated the people who make senior on schedule from the people who stall out, and it still will. The tools sitting next to you have just changed.

If this resonates, I wrote about what makes someone ready to be delegated to in Delegation in Modern Public Accounting and Consulting, and about the broader partner track shift in Why Most People Don't Become Partner and What That Means for You.
