The average manager in the U.S. now has 12.1 direct reports, up from 10.9 a year earlier and nearly 50% more than when Gallup first measured it in 2013. Companies have cut layers, combined roles and asked the leaders who remain to carry more, while AI helps people turn out more work than ever. On paper, a leaner team is getting the same work done with fewer people.
What that math leaves out is what it does to each senior seat. When a company had more layers, a leader who was a step behind the business could be absorbed by the people around them. On a lean team there is nowhere for that gap to go, so the person in every senior seat matters more than it did even a few years ago.
Fewer layers, more weight on every seat
Most senior leaders today are player-coaches. In Gallup’s research, 97% of managers still do hands-on work on top of leading others, and the typical manager spends about 40% of the week on it. Add a bigger team and the role stretches in two directions at once, with more people who need direction and the same pile of individual work that never went away.
AI was supposed to ease that pressure, and in some ways it has. Executives in an Atlanta Fed survey expect AI to lift output per worker by about 3% this year. But more output is not the same as less work. After companies adopted AI, ActivTrak found time spent on email jumped 104% and time on chat and messaging rose 145%. People are producing more and are busier than ever, which makes it harder to tell from the outside whether a seat is truly working.
That is the quiet risk of a lean team. A leader can be overloaded, out of step with where the company is headed, or simply in the wrong role, and the output still looks fine for a long time, because AI and a few capable people around them keep filling the gaps.
Size isn’t what breaks a team
It would be easy to conclude that bigger teams are the problem, but Gallup’s data says otherwise. When it looked at managers leading very large teams of 25 or more people while carrying heavy hands-on workloads, the most talented managers kept their engagement up, while managers with less natural talent for the role saw engagement fall as their teams and workloads grew. Gallup’s own summary is that manager talent trumps span of control.
Feedback told the same story. Across studies covering more than 44,000 employees, workers who received meaningful feedback in the past week were highly engaged no matter how big their team was. The size of the team mattered far less than whether the person leading it was doing the part of the job only a leader can do.
For a company running lean, that changes the question. It is less about how many people one leader can manage and more about whether the right leader is in the seat.
What AI changes about the senior seat
AI is very good at the parts of leadership that used to fill a calendar: status reports, project tracking, first drafts and the deck for Thursday’s meeting. As more of that moves to software, a senior leader’s value shifts to the work AI cannot do, which is making the hard call, giving honest feedback, building the next layer of leaders and keeping a team pointed at the same goal.
That is a different job than many senior seats were hired for. A leader brought on three years ago because they could out-produce everyone else may now be competing with tools that produce faster, while the judgment and coaching the seat needs go underused.
A useful way to look at any senior seat is to look at the week rather than the title. How much of this leader’s time goes to work only they can do, and how much goes to work that AI or someone else could handle? The answer usually says more about the fit than a résumé or a performance review.
A team, not a family
When a seat isn’t working, many leaders hesitate because of a line most of us have used at some point: we’re a family here. It comes from a good place, but it sets the wrong standard. Family is permanent, and you don’t remove your brother from the family because he’s underperforming, so when a company sees itself that way, every honest conversation about a seat starts to feel like a betrayal.
A team works differently. Everyone has a role to play, and a leader’s job is to put people in positions where they can succeed and the team can win. That means coaching people, investing in them, trying them in a different role when something isn’t working, having the hard conversations early, and treating them incredibly well for as long as they’re on the team.
It also means being honest when this might not be the right team, role or coach for someone. Keeping a person in the wrong seat because you care about them isn’t always kindness. They might be capable of being a star somewhere else, with a different coach, a different system or a different mission, and we have watched plenty of leaders struggle in one company and thrive in the next. Caring about someone and needing to keep them on the team forever are not the same thing.
What to do with what you see
Looking honestly at a seat does not mean someone has to go. Sometimes the right move is a different seat for the same person, where their history and loyalty count for more. Sometimes the leader is ready to grow and simply needs the hands-on work taken off their plate so they can lead. And sometimes the honest answer is that the company has outgrown the role, or the role has outgrown the person.
Whichever it turns out to be, the first step is the same: get clear on what the seat has to deliver before deciding anything about the person in it. Agree with your leadership team on the outcomes for the next year, the kind of leader the team needs at its current size, and what would make someone fail in the role. Once that picture is on paper, the conversation is about what the business needs rather than one person’s performance. Our Role Visioning tool is built for exactly that step.
If the answer is a new hire, that same picture will shape the whole search, and it helps to know the six assumptions that trip up most senior hires before you start.
Lean teams leave less room to wait
On a team with more layers, a seat that isn’t quite working can drift for years before anyone feels it. On a lean team, the cost shows up faster: in decisions that wait on one overloaded person, in strong people quietly carrying part of someone else’s role, and eventually in the people who leave because of it. The companies that run lean well are the ones that look at every senior seat on a regular rhythm and act while every option is still open.
