Three weeks into the new director's tenure, the engineering team had developed a habit nobody named out loud. When a release decision needed making, several of them still walked past her office and down the hall to the VP who used to run the group. He had moved up, with a new title and a corner office two floors away. He also answered every question they carried to him, because answering felt like generosity and turning them away felt like abandonment. The director held the role on paper, while the authority had quietly stayed with him.

McKinsey recently studied two hundred family-business successions across fifty countries, and the finding should unsettle anyone planning a leadership handoff. Companies tend to underperform for roughly five years after the transition, and the cause usually traces to the person leaving rather than the person arriving (McKinsey research, reported by Fortune, May 2026). The heir gets scrutinized for months before the seat is hers. The board weighs her readiness and her judgment, and then she takes over, and the organization spends half a decade absorbing the cost of a predecessor who never really left.

The handoff you planned and the one that happened

Most organizations treat succession as a selection problem, a matter of finding the right person and giving them the title before marking the date as done. Underneath that approach sits a quiet assumption that authority arrives with the position. It does not. Authority lives in where decisions actually route, and they route toward whoever the organization trusts to own the result. A title change does not relocate that trust. Behavior does, and it moves slowly, only when the behavior around the new leader changes too.

This is not only about chief executives and named successions. The same mechanism appears whenever a senior leader hands a function to a new director or steps back from a project she once ran. What tends to fail is the relinquishing. The departing leader keeps a hand on the decisions, often without noticing, and the organization reads that hand as the real signal of who remains in charge.

Why the person leaving is the one to watch

The reason sits in identity more than in process. For someone who built a function or a company, the role is not a job they happen to hold. It is a large part of how they understand who they are, so letting go of it can feel close to erasure. They stay near it. They take the advisor seat, or the open-door posture of someone who is just there if needed, and they mean all of it kindly. The impact runs in the opposite direction from the intent. Every question the predecessor answers is a decision the successor did not get to make. Every gentle correction offered in a hallway tells the team where the real authority still sits. Over a few months this hardens into a system. People learn that the fastest route to a dependable answer goes around the new leader, and once that path is worn in, no amount of competence lets her establish authority, because the organization keeps routing past her to the person it already trusts.

You can read the real state of any handoff by watching where the hard questions go. As long as they travel to the person who left, the transition exists on paper and nowhere else.

What a clean handoff requires

The repair lives in structure more than in goodwill. The predecessor needs a bounded role with an expiration date, written down and visible to the team, so everyone can see where the old authority ends. The successor needs to make one consequential, hard-to-reverse decision early, the kind that announces the system has changed and cannot be walked back to the old desk. And the predecessor has to do the harder part, sending every operational question back to the successor even when answering would be quicker and would feel better. Organizations that manage this treat the departure as the event that actually matters, and they design for it instead of assuming good intentions will carry the day.

If you have lived through a handoff that looked clean on the org chart and stalled in practice, the useful question is a plain one. When the hard calls came up in those first months, who did people actually go to? The answer usually says more than the announcement did. I am curious what you have seen, from either side of the change.
