Before the Handover: A Six-Month Rehearsal for Your Successor

Succession is rarely a scheduling problem. It is a judgement problem. UK owner-managers and boards can produce a plan, name a likely successor and describe a timetable, yet still discover at the point of handover that the candidate has never carried the weight of the role. The plan was a document. It was not a test.

A rehearsal is different. It takes place while there is still time to correct the outcome. It gives the number two real decisions, not shadow responsibilities. It invites external scrutiny, not just internal reassurance. And it includes a clear off-ramp, because a succession process that cannot conclude that the candidate is not ready is not a process at all.

A plan is not a rehearsal

Most succession plans answer the wrong question. They ask who could do the job, not whether they can do it under realistic conditions. A curriculum vitae can show technical competence. A series of internal presentations can show fluency. Neither shows how a candidate behaves when a customer is lost, a key manager resigns or a material investment goes wrong.

The rehearsal is a structured six-month test. It should be agreed in advance by the owner-manager, the board and the candidate. The candidate should know that the purpose is to test readiness, not to perform readiness. The owner-manager should know that the purpose is to observe, not to intervene at the first sign of discomfort.

Month one: define the decision charter

The first month is for boundaries. The owner-manager and the candidate should agree a written decision charter. It should list the decisions that will be delegated, the decisions that remain reserved, the financial thresholds, the reporting rhythm and the circumstances in which the owner-manager will step back in.

The charter should be specific. Delegating “commercial matters” is not a test. Delegating pricing decisions below a stated threshold, hiring approvals for two named roles and responsibility for a particular customer renewal is a test. The candidate should have the authority to act, and the owner-manager should have the discipline not to reverse the decision unless the charter has been breached.

This is also the moment to agree how the rehearsal will be assessed. The criteria should be behavioural and commercial: quality of judgement, willingness to seek advice, treatment of dissent, handling of poor performance, and the ability to communicate a decision to the board and the wider team.

Months two and three: delegate real decisions

The second and third months are the core of the rehearsal. The candidate should chair selected meetings, lead a material piece of work and take decisions that would normally sit with the owner-manager. The owner-manager should attend less, not more. If the candidate is never allowed to make an unpopular decision, the test is incomplete.

The board should see the candidate in action. Not through a presentation, but through the ordinary rhythm of papers, questions and follow-up. Non-executive directors are often well placed to observe whether the candidate answers a question directly, distinguishes between confidence and competence, and knows when to say that they do not know.

The owner-manager should keep a simple record. What was delegated? What was decided? What was escalated? What was avoided? The record should be factual, not a diary of grievances. At the end of month three, the owner-manager and the chair should review it together.

Month four: invite outside scrutiny

Internal observation can become comfortable. Month four should introduce an external perspective. This need not be elaborate. A trusted adviser, a non-executive director from another sector, a customer with no axe to grind or a peer from a related industry can provide a useful check.

The external reviewer should be asked a narrow question: what would concern you if this person were in the role within twelve months? That framing is more useful than a general appraisal. It invites specific observations about judgement, resilience, delegation and the ability to hold a senior team together.

The candidate should meet the reviewer and hear the feedback directly. The owner-manager should not filter it. If the feedback is difficult, it is better heard in month four than in the week after the handover.

Month five: stress-test the candidate

By month five, the rehearsal should include a deliberate stress test. This does not mean manufacturing a crisis. It means selecting a real pressure point that the business is already facing and asking the candidate to lead the response. It could be a difficult customer negotiation, a cost reduction exercise, a regulatory query or a senior hire that has not worked out.

The owner-manager should agree in advance what support will be available. The candidate should not be abandoned, but nor should the owner-manager take over. The test is whether the candidate can absorb pressure without becoming either brittle or reckless. Can they seek advice without losing authority? Can they make a decision with incomplete information? Can they communicate it to the board without overclaiming certainty?

Month six: decide, with a clear off-ramp

The final month should end with a formal review. The owner-manager, the chair and, where appropriate, the board should consider the evidence gathered over the previous five months. The question is not whether the candidate is likeable or loyal. It is whether they are ready.

There should be three possible outcomes. The first is ready: the candidate takes the role on a defined timetable. The second is ready with conditions: a further development period with specific milestones, a mentor or a narrower scope. The third is not ready: the candidate remains in their current role, or leaves if that is the appropriate outcome, and the search continues.

The off-ramp is essential. Without it, the rehearsal becomes a coronation. The candidate should know from the outset that a not ready outcome is a legitimate result, not a personal failure. The owner-manager should know that using the off-ramp is a sign of governance maturity, not indecision.

What the owner-manager must not do

The most common failure is interference dressed as support. The owner-manager who attends every meeting, answers every difficult question and quietly reverses decisions is not rehearsing succession. They are delaying it.

The second failure is secrecy. If the candidate does not know the criteria, the process becomes a test of political instinct rather than readiness. The third failure is treating the board as a rubber stamp. Non-executive directors should see the evidence and be invited to challenge the conclusion.

Signs the rehearsal is working

A successful rehearsal produces a clearer answer than a plan ever could. The board should be able to point to decisions the candidate made, pressures they handled and feedback they received. The candidate should be able to describe what they found difficult and what they would do differently. The owner-manager should be able to say, with evidence, whether the handover is credible.

Succession is too important to be left to a document in a drawer. A six-month rehearsal does not guarantee a perfect outcome. It does something more useful: it gives the owner-manager and the board the evidence to make a sound judgement while there is still time to act on it.
