How Should a Business Plan Executive Succession?

Succession is one of the few board responsibilities where doing nothing has no immediate cost. Nothing breaks this quarter because there is no plan for the Managing Director's eventual departure.

The cost arrives all at once, usually at the worst moment, and it is paid in months of drift rather than in money.

What succession planning is not

• A named heir for every role, recorded once and never revisited.
• A promise of promotion, which creates an obligation the board may not be able to honour.
• A document. The document is a by-product; the value is in the conversation the board has to have to produce it.
• Exclusively about the Chief Executive. The roles that hurt most when they leave unexpectedly are often the ones holding operational or technical knowledge nobody else has.

Start by identifying dependency, not seniority

The right starting question is not who is most senior. It is where the business is most dependent on one person, and what would stop working within a month if that person were unavailable.

In owner-managed and mid-sized businesses the answer is frequently uncomfortable. Key customer relationships held personally. Pricing judgement that exists nowhere in writing. Supplier terms negotiated on the strength of a twenty-year relationship. Technical approvals that only one person is qualified to sign.

Planned succession: the twelve-to-eighteen-month shape

Where a departure is known in advance — retirement, a founder stepping back, a fixed-term commitment ending — time is the asset. Spending it is the discipline most businesses lack.

1. 01Define the role the business will need next, not the role that exists now. The successor inherits a different company from the one the incumbent joined.
2. 02Assess internal candidates honestly and tell them where they stand. Ambiguity at this stage loses good people.
3. 03Decide internal or external, and be prepared to run both routes in parallel where the stakes justify it.
4. 04Run the external process with proper confidentiality if the departure is not yet public.
5. 05Overlap the handover deliberately. Relationships, context and judgement transfer in conversations, not in documents.
6. 06Define what the outgoing executive does afterwards — Chair, non-executive, adviser, or genuinely nothing. Unclear post-transition roles undermine successors more than anything else.

Internal successor or external appointment?

Neither is inherently right. The decision should turn on what the next stage requires.

Judge an internal candidate on evidence of decisions made, not on length of service or technical excellence. The most common succession failure is promoting the best performer in a function into the leadership of it, without ever having tested whether they can lead.

Emergency succession: the plan nobody wants to write

Illness, resignation with immediate effect, a departure the board initiates. The requirement here is different: not the right long-term answer but a safe short-term one, decided before the pressure arrives.

• Who holds the role on day one? Name a person for each critical position, and make sure they know.
• What decisions can they take, and what comes to the board?
• What is said, to whom, and in what order — team, customers, suppliers, lenders, investors?
• At what point does the business bring in interim leadership rather than stretching the executive team?
• How does the permanent process start without being driven by panic?

Interim leadership earns its place here. It buys the time to run a proper permanent process instead of appointing the first available candidate under pressure — which is how businesses acquire the executive they regret.

Where succession planning quietly fails

• It is written once and filed. Business needs change; a successor identified three years ago may now be wrong for the role.
• The incumbent is asked to identify their own successor and has no incentive to do it seriously.
• Development is promised but never resourced — no decisions delegated, no exposure to the board, no stretch.
• The board discusses it only when a departure is already in motion.
• The plan covers the Chief Executive and nobody else.

Governance, briefly

Directors have statutory duties, including a duty to promote the success of the company and to exercise reasonable care, skill and diligence. Succession planning is one of the places where those duties become concrete: continuity of leadership is a foreseeable risk, and boards are expected to have considered it. Larger and listed companies work to more formal expectations under the UK Corporate Governance Code, and where questions of employment or shareholder agreements arise, take proper legal advice — this article is commercial guidance, not legal advice.
