The dominant operating model in professional services is the pyramid. A few partners sell the work. A wider layer of managers run it. A much wider layer of analysts produce most of the deliverables. The economics work because the analysts cost less than they bill for.
We have built AAA around a different model: senior practitioners do the work themselves. Smaller teams, no pyramids. Here is why.
Why the pyramid model fails the client
The person who sold the engagement is rarely the person doing the engagement. The senior practitioner who wrote the proposal is occupied selling the next engagement before the current one finishes. The work transfers down the pyramid — and the judgement that was supposed to be on the client side transfers with it.
Clients notice. The first conversation is excellent. The second conversation is good. By the third conversation, the team is junior, the answers are templated, and the original promise has quietly degraded.
What senior-only changes
When the practitioner who recommends is the practitioner who delivers, the work changes in three measurable ways. Recommendations are tighter, because the person making them has to deliver against them. Sequencing is sharper, because the person planning the work has done it before. And client confidence compounds, because the second conversation is at the same level as the first.
The math
Senior-only teams are smaller and more expensive per head. They are also faster, produce more durable outcomes, and require less management overhead. In practice the total cost of engagement is comparable to the pyramid model — and the outcome differential is large.
It is also a different hiring model. We hire fewer people, more carefully, and we keep them busy with work that uses the seniority we hired for. The model only works if the firm refuses to take work that does not need that seniority.
Why it is, in the end, a hiring decision
Operating models are downstream of hiring. A pyramid is staffed by hiring graduates in volume. A senior practice is staffed by hiring senior practitioners in small numbers. Each model produces the work the staffing model is capable of producing.
We built AAA the second way on purpose. The senior team is the firm. The deliverable is what the senior team would actually do if they owned the problem. That is the brand. It is also the operating model.
