James Polk ran the executive branch the way a man handles a wallet he will not let anyone else carry. He came into office in 1845 with four aims, held most of the working detail in his own head, treated delegation as a kind of leakage, and drove himself well past the point where a sensible person would have handed something off. He got all four done in a single term, which is a claim almost no president can make. He left office in March of 1849 and was dead by June. The historians who admire the record tend to add, with some discomfort, that the government he built around himself could not really function without the man who insisted on being most of it.

Boards are running a gentler version of that same experiment right now, and the word they use for it is efficiency.

Over the past decade the number of executives carrying more than two titles has more than doubled, a rise put at 121 percent, with roughly a tenth of that growth arriving in just the last two years. That number comes from a Korn Ferry analysis, though by way of a trade outlet reporting on it rather than from Korn Ferry's own published pages, so take the precise figure as directional.2 Korn Ferry also has a stake in how the story gets told, since it sells the search and succession work that a reshuffled C-suite tends to need. The pattern turns up plainly enough in the figures it does publish. Roles that used to sit apart are being folded together and set on one desk.

What the reshuffle actually looks like

Korn Ferry's own account of the trend opens with a chief human resources officer running a meeting about a data center build, then a debrief with engineers over a misbehaving AI chatbot, then a progress update to the chief executive, none of which used to belong anywhere near an HR seat.1 Firms are collapsing a chief financial officer and a chief operating officer into one person, or a marketing chief and a communications chief into another, and in some cases merging human resources and technology into a single function under one leader.1 The visible edge of it shows up in the counts, with chief marketing officer roles down eight percent in a year and chief communications officer roles down six.1 Korn Ferry's Dan Petrossi describes the appeal plainly, that the more consolidated top leadership is, the faster you can move, while his colleague Lucy Bosworth notes that the approach shrinks the span of control to a smaller, tighter group and frees a chief executive to concentrate on priorities like AI adoption and growth.1

Speed is the honest part of the pitch. Fewer people in the decision means fewer calendars to align and fewer approvals to chase, and doing it without new headcount is attractive in a year when most of the free budget is going toward an AI build. On a slide it reads as discipline.

The assumption hiding inside the org chart

What the tidy chart assumes is that a function is a box you can lift off one desk and set on another without it weighing anything. It is not. A function is a running set of judgments that only get better with attention, and attention is the exact resource a leader carrying several mandates has less of. The marketing chief who now also owns communications did not lose the skills for either job. The room to do either one with care is what gets thinner. When a single head holds both the pricing decision and the crisis statement, something has to give, and the place it gives way is usually the one nobody was watching.

The more of an organization you fold into one executive, the more of it walks out the door on the day that executive does.

An operator's objection

I spent years on the other side of this move. In an intelligence shop and later coaching delivery teams, most of the work of building something that holds up is the work of spreading ownership wide enough that no single person's absence stops the mission. You design for the bad day on purpose. You make sure the judgment lives in more than one head so a resignation, an illness, or a competing offer does not take a whole capability with it. Consolidation runs against that instinct. Folding several functions into one leader reverses the accountability that a resilient operation works hard to spread, and it does so at the top of the house, where the loss travels furthest.

There is a succession cost sitting underneath the efficiency case too. Boards will say, not unreasonably, that handing a rising executive a second function is how you test them and get them ready for more.2 The trouble is that the same move erases the seats other people would have grown into. The bench a company will need in three years is built out of the roles it is collapsing today. Move fast enough and you arrive at that future with one very capable, very tired person and almost no one seasoned enough to relieve them.

Polk had an excuse the modern C-suite does not. He had four years and a continent to reshape and no theory of management to know better. A board flattening its leadership in 2026 has a century of evidence about what happens when a system depends on one irreplaceable person, and it is choosing the speed anyway. That can be the right call. It is only the right call if someone in the room has honestly priced what the organization loses on the day the arrangement ends, and my experience is that this is the part of the conversation that most often gets skipped.

So here is the question worth putting on the table before the next reorg deck gets approved. When the chart got simpler, did the work underneath it actually get simpler, or did it just get harder to see who is holding the whole thing up?
