The Provisional Chair: A Controlled Test of Succession Judgement

Succession planning in UK owner-managed companies is frequently reduced to a document set: a shareholders' agreement, a will, a board resolution, perhaps a tax memorandum. These are necessary instruments, but they answer a narrow question. They record what the owners intend to happen. They do not establish whether the intended successor can carry the weight of the role when the incumbent is no longer in the room.

That distinction matters most in firms where authority has been personal rather than procedural. The founder or long-standing managing director may be the person the bank calls, the client rings when a project goes wrong and the senior team checks with before a difficult call. A named successor can appear credible on paper and still be untested in precisely those moments. The practical response is not another planning document. It is a controlled rehearsal of judgement.

The limits of a signed plan

A succession plan can confirm intent, allocate shares and set a timetable. It cannot demonstrate how a successor will handle a covenant conversation with the bank, a client demanding a fee reduction after a missed milestone, or a senior employee who believes the change will not really happen. These are not administrative events. They are tests of judgement under pressure, and they are where many handovers quietly falter.

The incumbent's continued presence compounds the problem. Even when a successor has the title, colleagues and external parties may still route decisions around them. The result is a form of shadow authority: the successor holds the role, but not yet the room. A rehearsal period is designed to make that gap visible while the consequences remain contained.

A controlled transfer of decision rights

The most useful rehearsal is a defined period - typically two full working weeks - in which the intended successor acts as provisional chair of the management agenda. The incumbent does not disappear, but moves to an observer role. The purpose is not to stage a performance. It is to create evidence.

During the period, the successor should hold a specified set of decisions that matter to the business: operational spend within an agreed threshold, prioritisation of competing client demands, escalation of supplier issues, preparation for a bank or lender conversation, and the awkward client calls that cannot be delegated indefinitely. The incumbent watches, keeps a written record and resists the urge to rescue. A clear emergency brake remains in place for statutory, safety or material financial risk, but it should be used rarely and recorded when it is.

The period should be authorised formally, whether by a board minute, a partnership resolution or a written note signed by the incumbent and successor. This is not bureaucracy for its own sake. It protects the successor's authority, gives the senior team a clear signal and prevents the exercise from being dismissed later as an informal chat.

Designing the rehearsal

A workable rehearsal needs more structure than a diary note. Four elements deserve attention.

First, scope. The successor should hold enough decisions to be tested, but not so many that the period becomes an uncontrolled handover. A written schedule of decision rights is more useful than a general instruction to take the lead. It should state which matters the successor decides alone, which require consultation and which remain with the incumbent.

Second, stakeholders. The bank relationship manager, the largest two or three clients and the senior team should be briefed appropriately. This need not be presented as a dramatic transition announcement. It can be described as a planned period of delegated authority. The aim is to ensure that the successor is genuinely dealing with the relationship, not merely preparing papers for the incumbent to approve.

Third, evidence. A simple decision log is sufficient: date, issue, decision taken, rationale, parties consulted and outcome. Meeting notes and short stakeholder feedback should sit alongside it. The record should be factual rather than evaluative. The review can interpret it later.

Fourth, observer discipline. The incumbent's role is the hardest part of the exercise. Watching a capable colleague make a decision differently from the way one would have made it is uncomfortable. Intervening too early destroys the value of the test. The incumbent should note concerns and raise them in the debrief, unless the emergency brake genuinely applies.

What the rehearsal tends to expose

The gaps that surface are rarely about technical competence. More often they concern authority and tempo. A successor may defer to the incumbent's known preferences rather than forming an independent view. They may avoid a cash conversation because it feels impolite, or over-rely on one trusted lieutenant rather than using the wider team. They may handle a client escalation well in substance but fail to close the loop with the account team. They may be reluctant to say no to a long-standing customer whose request no longer makes commercial sense.

These are useful findings. They are also far cheaper to address before the incumbent leaves than after. A rehearsal can show that the successor needs a clearer mandate on pricing exceptions, more exposure to lender reporting, or coaching in difficult conversations. It can also show that the incumbent has been holding decisions that should have been delegated years ago. Both conclusions improve the handover.

The debrief matters as much as the period

A rehearsal without a structured review is merely an interruption. Within two working days, the incumbent, successor and, where appropriate, one non-executive or trusted adviser should review the evidence. The discussion should focus on three questions: where did the successor exercise sound judgement, where did authority stall, and what should change before the next period?

The output should be short. Two or three development actions are more likely to be acted upon than a lengthy assessment. A second rehearsal after six months can test whether those actions have taken hold. If material gaps remain, the firm has a genuine reason to adjust the timetable or redesign the role. That is not a failure of the successor. It is the purpose of testing.

Guardrails and communication

A provisional period must not undermine the incumbent's legal authority or create ambiguity for staff and external parties. The written terms should state the duration, the decision rights, the escalation route and the confidentiality expectations. The incumbent remains accountable for statutory duties unless and until a formal appointment is made. The successor should be clear that the period is a delegated test, not a public coronation.

For family-owned firms, it can also be useful to agree in advance how family expectations will be kept separate from management evidence. The rehearsal is about capability, not lineage. That distinction should be stated plainly.

Conclusion

Succession is often treated as a ceremony to be completed at the end of an owner's tenure. It is better understood as a capability to be examined throughout. A short, governed period in which the intended successor holds real decisions provides evidence that no document can supply. It tests judgement, exposes gaps and gives the incumbent a final opportunity to transfer authority rather than merely announce it. For UK owner-managed firms, where relationships and implicit knowledge carry so much weight, that evidence is worth more than another signed plan.
