Who Steps In on Monday? A Three-Hour Drill for Leadership Continuity

A plan is not a rehearsal

Almost every UK board can point to a succession plan. Far fewer can demonstrate that the plan has been exercised under conditions resembling a real departure: sudden, unplanned and deeply inconvenient. The gap between the two is where continuity risk accumulates.

The distinction is not academic. Provision 17 of the UK Corporate Governance Code asks the board to satisfy itself that plans are in place for orderly succession to board and senior management positions, and the supporting principles expect those plans to be kept under review rather than filed and forgotten. A three-hour session, run annually with disciplined preparation, is generally enough to move a board from documentation to something closer to confidence.

What follows is not a talent review. It is a drill, closer in spirit to a business continuity exercise than to an appraisal cycle, and it belongs in the risk register alongside cyber, supply chain and liquidity.

Pre-work: three documents, no more

The temptation to circulate a ninety-page leadership dossier should be resisted. Boards that prepare well tend to use three items:

• A role specification and delegation schedule for the chief executive and the chief financial officer, stating plainly which decisions can be taken by an interim incumbent and which cannot.
• A bench map of internal candidates, graded by readiness rather than seniority, with the evidence behind each grade noted in a line or two.
• A contact sheet of external advisers — search firms, interim providers, employment counsel — with current terms, so that no one is hunting for a telephone number on the morning it matters.

The agenda, block by block

00:00–00:25 The Monday morning scenario

The chair opens with a single question: the chief executive is admitted to hospital this morning and will be absent for eight weeks. Who is in charge at nine o'clock, and what does that person decide before lunch? The company secretary records the answers without correction. The purpose of this block is exposure, not solution. Non-executives should resist the urge to start solving prematurely.

00:25–00:60 Interim cover and delegated authority

This block is unglamorous and decisive. Which signatures remain valid? What are the bank mandate thresholds? Who may commit capital, hire, settle litigation or speak to lenders? In dual-regulated financial services firms, the treatment of senior manager responsibilities and the timing of any regulatory notification needs to be stated, not assumed. For listed companies, the point at which an announcement becomes necessary under the market abuse regime should be agreed in advance, with the general counsel present.

01:00–01:45 The internal bench

The board works through the two-below population. For each name: what could this person hold tomorrow, in twelve months, in three years? What is the evidence? Where are the exposure gaps — no profit and loss accountability, no investor contact, no regulatory interface, no experience of a cyclical downturn? The exercise is most useful when it produces an uncomfortable answer about at least one role.

01:45–02:20 External contingency

The market for chief executives and finance directors is measured in months, not weeks. This block should confront notice periods, buy-out expectations, the headroom available under the existing remuneration policy, and the reputational cost of a rushed external appointment. Boards that have never priced an external search often overestimate how quickly one can be completed.

02:20–03:00 Decisions, owners and dates

Every gap identified in the previous two hours receives a name, an owner and a date. Nothing else is agreed. A session that ends without this discipline has been an interesting conversation rather than a governance intervention.

Four pitfalls that surface in almost every session

The finance director as afterthought. Succession energy gravitates towards the chief executive. In practice, the finance function is where sudden absence bites fastest: covenant reporting, audit timelines and market communication all depend on it.

Confusing performance with readiness. A high-performing divisional director may be two years and one significant stretch assignment away from the top job. The drill should distinguish sharply between the two judgements.

The sealed envelope problem. Where succession materials sit with one individual and no deputy, the plan is itself a concentration risk. The company secretary should hold a current version, and the chair a duplicate.

Mistaking a name for a plan. Naming a preferred successor is not the same as preparing one. The drill should test development actions, not merely preferences.

The questions non-executives should ask

• If the chief executive were absent for a quarter, which three decisions would stall, and why?
• Has the internal candidate actually been tested against a board, an investor audience and a lender?
• Does the interim appointment require shareholder or regulatory engagement, and who owns that conversation?
• What would we pay for an external appointment, and does our existing policy allow it without a binding vote?
• Which of our named successors has never been told that they are on the list?
• When did the nomination committee last review this plan against the current strategy, rather than last year's?
• Who besides the chair could open the file at eight o'clock on a Monday morning?

Owning the outcome

The session should produce minutes of a particular kind: a list of gaps, an owner for each, and a review date. Six months later, the nomination committee should confirm what has changed — not merely that the plan has been re-read.

Continuity is rarely lost because a board lacked a plan. It is lost because the plan was never asked a difficult question. Three hours, honestly spent, is usually enough to find out where the answers are thin.
