Chief executive succession is one of the few governance practices that has genuinely improved. Boards now maintain named internal candidates, review them annually, run development plans against identified gaps and can describe the emergency answer without leaving the room. Two decades of pressure produced a real discipline.
The discipline stops almost exactly one layer below. Ask the same board who replaces the head of manufacturing, the general counsel or the person who has run the largest customer relationship for eleven years, and the conversation changes character. There is usually a name offered with hedging, sometimes a list, and rarely a plan.
The roles that actually break
This matters because the operating risk is not distributed the way the org chart suggests. A chief executive departing unexpectedly is disruptive and highly visible, and the institution is built to absorb it — there is an interim, a search firm, a board committee and a well-worn script. The company keeps running while it happens.
The roles that stop a company are further down and harder to see. They are held by people who have accumulated undocumented knowledge over a long tenure: the plant manager who knows which supplier will actually expedite, the regulatory lead with the relationship at the agency, the engineer who is the only person who understands why a system was built the way it was. None of that appears in a job description, so none of it appears in a succession review that works from job descriptions.
The structural cause is recent and self-inflicted. A decade of flattening removed the layer where this depth was traditionally built. The middle management tier that companies cut and are now quietly rebuilding was the mechanism by which someone practised running a function at reduced scale before running it fully. Remove the rung and people arrive at the senior role having never done a smaller version of it, which shows up as a succession problem years after it was created as an org design decision.
Companies that have addressed it treat the exercise as an inventory rather than a chart. The useful question is not which roles are senior but which roles, if vacated on Monday, would produce a consequence the company could not manage within a quarter — and the answers routinely include positions that are nowhere near the top of the structure. Some of the most exposed roles carry no direct reports at all.
The fix is mostly unglamorous. Deliberate deputising, documented handovers, rotations that are genuinely inconvenient, and a willingness to move people before they are obviously ready. That last one is where most programmes fail, because the manager holding the strongest internal candidate has every incentive to keep them, which is the same friction that makes internal mobility the cheapest recruiting channel that nobody uses.
Founder-led companies feel the gap most sharply, having usually solved it once at the top by hiring an operator alongside the founder and concluded from that success that the problem was addressed. It was addressed for one seat.
The tell is simple enough to run in a meeting. Ask for the five roles whose sudden vacancy would hurt most, and then ask who fills each of them. The length of the pause is the answer.
One popular workaround makes the gap worse rather than better: the two-in-a-box job is back.
The deeper failure sits upstream of the bench: a succession fight is a design failure, not a clash of personalities.
