During an annual board discussion, a director asks a straightforward question: “If our chief executive became unavailable on Monday, who could lead the organisation?”

The room becomes noticeably less certain.

Several executives could maintain operations for a short period. One has strong commercial credibility. Another understands the organisation better than anyone. A third is respected by the board, but has limited experience outside their function.

None is considered ready.

The conversation quickly turns towards the chief executive’s exceptional contribution. The organisation is entering a critical stage. The timing of a transition would be difficult. The CEO holds relationships, history and knowledge that would be almost impossible to replace.

These statements may all be true. They also confirm the problem. If the organisation cannot imagine functioning without one person, it has not built leadership strength. It has built dependency.

Indispensability Is a Flattering Form of Failure

Senior leaders are often praised for becoming indispensable. They hold the most important relationships. They intervene when major decisions stall. They carry the organisation’s story, reassure investors, retain key clients and resolve tensions that others cannot manage.

Their value is undeniable. But when too much judgement, trust and authority accumulates around one person, individual strength begins to produce institutional weakness. Decisions wait for the CEO. Executives learn to escalate rather than resolve. External stakeholders build relationships with the individual rather than the organisation. Potential successors remain competent within their functions but underexposed to enterprise leadership.

The chief executive becomes increasingly necessary because the system has adapted around their necessity.

This is not always a deliberate accumulation of power. It often develops through success. The CEO repeatedly steps in because they are effective. The immediate issue is solved, while the long-term capability of the organisation remains unchanged.

Eventually, dependency is mistaken for evidence of exceptional leadership. A leader can be highly valuable without making the organisation vulnerable to their absence. The distinction is crucial.

Succession Is Not Departure Planning

Many boards begin serious succession conversations only when the CEO indicates an intention to leave.

By then, succession has become a deadline. Potential candidates must be assessed quickly. Development gaps that required several years must somehow be closed in several months. The board begins an external search while describing internal development as a priority it had always taken seriously.

This is not succession planning. It is replacement activity.

Succession should begin while the current chief executive is performing well, has no immediate plans to leave and can still play a meaningful role in developing future leadership capacity. The objective is not to accelerate the CEO’s departure. It is to ensure that the organisation retains strategic continuity under a range of circumstances, including those nobody expects.

A mature succession process distinguishes between three questions:

• Who can provide emergency leadership tomorrow?
• Who could become a credible CEO within the next one to three years?
• What leadership capabilities will the organisation require beyond the current strategic cycle?

These questions may produce different answers. Treating them as one creates false confidence.

The executive capable of stabilising the organisation during an emergency may not be the right person to lead its future transformation. The strongest long-term candidate may still require experience that cannot be gained after the vacancy occurs.

The Successor Should Not Be a Copy

Boards often assess potential successors against the current chief executive. Does the candidate possess the same gravitas? The same commercial instinct? The same command of the organisation? Can they manage relationships in the same way?

This comparison is understandable and frequently misleading. The next chief executive will not inherit the organisation the current CEO inherited. They will lead a different business, in a different context, facing different expectations.

The founder who created momentum through personal energy may need to be followed by a leader capable of institutionalising decision-making. The operational CEO who restored discipline may need to be succeeded by someone who can reopen innovation. The leader who grew the domestic business may not possess the capabilities needed for international expansion.

Succession should therefore begin with the future of the organisation, not the personality of the incumbent.

• What strategic tensions will define the next five years?
• Which capabilities will become more important?
• What must be preserved, and what will need to change?
• Where is the organisation likely to become vulnerable?

Only then should the board define the leadership profile.

Otherwise, succession becomes an attempt to reproduce yesterday’s success after the conditions that created it have changed.

The CEO Cannot Own Succession Alone

The current chief executive should play an important role in identifying and developing senior talent. They observe candidates in situations the board rarely sees and understand the complexity of the role from the inside.

But the CEO should not control the process.

Every incumbent has preferences, loyalties and blind spots. Some favour candidates who think similarly to them. Others support executives who are highly dependable but insufficiently independent. A strong potential successor may be unconsciously held back because their presence alters the balance of power around the top role.

There are also chief executives who sincerely support succession in theory but struggle with its emotional reality. A credible successor is evidence that the organisation can continue without them.

For leaders whose identity has become closely connected to the institution, that can be difficult to welcome. Development opportunities are delayed. Candidates remain “not quite ready”. The criteria shift whenever one person begins to emerge.

No manipulation needs to occur. Self-protection can operate quietly.

This is why the board must own succession. It should value the CEO’s judgement without outsourcing its responsibility to that judgement.

Potential Is Meaningless Without Exposure

Many succession plans contain impressive names. Executives are classified as high potential, ready later or possible future candidates. Their development needs are documented. The board reviews the list annually.

Nothing material changes.

The commercial leader still lacks operational experience. The functional expert has never led across the enterprise. The internal candidate attends board meetings but is invited only to present prepared material. No one has managed a significant crisis, difficult stakeholder environment or transformation beyond their existing area.

The plan describes readiness without creating it. Future chief executives do not develop through labels. They develop through assignments that reveal judgement. They need opportunities to lead across functions, manage competing interests, take responsibility for outcomes beyond their expertise and make decisions with incomplete information. They must build credibility with the board and external stakeholders before the transition, not during it.

This involves risk. A development assignment may expose limitations. A previously impressive executive may struggle when moved beyond familiar territory.

That is precisely why the exposure is necessary. It is better to discover a candidate’s limitations while there is time to develop or reconsider them than after the appointment has been announced.

Talent Reviews Can Become Organisational Theatre

Succession plans often look stronger on paper than they are in reality.

A candidate is described as ready in two years, then receives no assignment that would materially increase readiness. Development actions remain broad: greater visibility, broader exposure, more strategic thinking. No one defines what experience must be gained, who will create the opportunity or how progress will be judged.

The candidate remains two years away for the next four years. Boards should be suspicious of succession language that cannot be translated into evidence.

• What has the individual led that prepares them for enterprise accountability?
• How do they respond when their authority is challenged?
• Can they make an unpopular decision without becoming defensive or isolated?
• Do strong people want to work for them?
• How do they handle a problem that cannot be solved through their technical expertise?
• Can they represent the organisation credibly outside their existing network?
• Where has their judgement failed, and what did they learn?

Readiness is not a personality impression. It is a conclusion supported by behaviour across demanding contexts.

External Search Is Not a Substitute for Internal Strength

There are situations in which the best successor will come from outside. The organisation may require capabilities that do not exist internally, or a level of change that an internal candidate is unlikely to initiate.

An external appointment can be the right strategic decision. It should not be used to disguise years of neglected leadership development.

A board that repeatedly looks outside because no internal executive is ready should examine the system that produced that outcome. Perhaps high-potential people were retained in narrow roles because they performed too well to move. Perhaps the CEO surrounded themselves with reliable operators but few independent thinkers. Perhaps leadership development focused on programmes while critical assignments continued to go to the same trusted individuals.

Buying leadership from the market does not repair a weak internal pipeline.

Nor does it remove transition risk. External candidates must learn the organisation, build trust and distinguish between what needs to change and what they simply do not yet understand. The strongest boards retain both options. They develop credible internal candidates while remaining willing to search externally if the future requires something different.

Founder Succession Requires a Different Conversation

In founder-led organisations, succession is rarely only about role transition. The company may carry the founder’s identity, relationships, instincts and personal standards. Employees may treat the founder’s judgement as the final reference point even after formal authority has moved elsewhere.

A successor can hold the title while the founder continues to hold the organisation’s emotional authority. Unless this is addressed honestly, the new chief executive inherits responsibility without full permission to lead.

Founder succession therefore requires explicit decisions about future involvement, decision rights, communication and boundaries. What role will the founder hold? Which decisions will belong entirely to the successor? How will disagreements be managed? What will employees and clients be told?

Ambiguity protects the founder from the emotional finality of transition. It leaves the successor exposed to competing centres of power. A successful handover requires more than choosing the next leader. It requires the current one to release the organisation sufficiently for leadership to become real.

What the Board Should Know Now

A board with a serious succession discipline should be able to answer:

• Who could assume temporary leadership immediately?
• Which internal candidates could become credible successors, and over what period?
• What evidence supports each assessment?
• Which experiences are candidates still missing?
• What will be done in the next twelve months to close those gaps?
• What future strategy is the successor being selected to lead?
• Where might the current CEO’s preferences be shaping the process?
• What relationships, knowledge or decisions remain dangerously concentrated?
• How would the organisation communicate and stabilise an unexpected transition?
• Is the board prepared to choose the right successor rather than the most familiar one?

If these questions create discomfort, that discomfort is useful. It exposes risk while there is still time to address it.

The Final Test of Leadership

Chief executives are remembered for growth, transformation, financial performance and the institutions they build. Their deeper legacy is revealed after they leave.

Does the organisation continue making strong decisions without their intervention? Have other leaders developed enough authority to carry the institution forward? Do key relationships belong to the organisation, or did they depart with the individual? Can the successor lead differently without being measured permanently against the past?

The most successful chief executive is not the one whose absence creates the greatest crisis. It is the one whose contribution remains visible even after their personal control is gone. If there is no credible successor, succession has not suddenly become a problem. The problem has been developing for years.

The vacancy merely makes it impossible to ignore.
