Succession Planning for Boards That Have Never Changed

A board that has held the same seats for eight years or more occupies a peculiar position. It is stable. It has institutional memory. Its members understand each other's working styles without needing to rehearse them. The governance literature tends to celebrate this coherence. What it often misses is that stability of this kind can become a form of blindness. The board has not yet tested its own capacity to change. It has not yet learned who will stay, who will leave, or what the organisation actually looks like once someone goes.

Succession planning in such a setting is not about managing the departure. It is about learning what the board does not currently know about itself. I observed this most clearly during my time at Castle, where a long-serving board suddenly faced the retirement of its longest-tenured independent director. The conversation that followed was not smooth. The board discovered, in the months before the transition, that it had built most of its decision-making patterns around that single person's presence. Not because he held formal power, but because his seniority had made everyone else quieter. Once the announcement was made, the board had to relearn how to speak.

The practical work of succession planning begins well before the formal search. It means naming what the board is actually doing when it makes decisions. A board that has not changed tends to have naturalised its own habits. Someone chairs meetings in a particular way. Dissent is raised in a particular forum, or not raised at all. Risk gets discussed, or it gets avoided. These patterns are invisible until you have to replace the person who set them. The moment you do, you are forced to ask whether those patterns served the organisation or merely served the comfort of the people in the room.

The FCA's governance expectations, and the frameworks that follow from the FTSE Women Leaders Review, both rest on a simple principle. Boards need to be able to think differently than they currently think. This becomes nearly impossible if no one has ever left. A board without turnover accumulates collective memory but loses the capacity for outside perspective. The new chair, the new independent director, the new audit committee lead, they arrive already knowing that the only path to influence in this particular room is to fit in quickly. They learn the board's language rather than bringing their own.

I have found that the most useful succession planning conversations do not actually focus on the role itself. They focus on what the board will need to learn from the change. Will there be a period where decision-making slows. Will there be a gap in a particular kind of expertise. Will there be a moment where someone, quite reasonably, decides to stay longer than planned because no one is ready yet. These are the real questions. I have seen organisations move from a five-year plan for independence to a two-year plan because the board forced itself to be honest about what it did not yet know how to do without a particular person.

The board that has never changed often carries an unexamined assumption. It believes it is more cohesive than it actually is. The assumption does not become visible until the first person leaves and the board realises that what felt like consensus was actually acquiescence. Some members have been waiting for someone else to move. Some have been protecting relationships that felt too valuable to disturb. The succession plan, done properly, brings all of this into the open before the vacancy is announced, not after.

A board beginning a genuine succession process for the first time should anticipate a moment of discomfort. That discomfort is not a sign that something has gone wrong. It is a sign that something is working. The board is finally asking itself what it would look like if it operated on its own terms, rather than on the terms that have inherited themselves over the years. The new chair or director arrives into that clarity rather than into a pretence of seamlessness. That is the difference between succession planning that is procedurally correct and succession planning that actually prepares an organisation to survive change.
