Succession planning is often triggered by a simple question: who could replace this person? But replacing an individual and replacing the capability they bring to an organisation are not necessarily the same thing.
When a senior or highly experienced person is expected to leave a business, attention naturally turns to succession.
Who could step into the role? Is there somebody internally? If not, what would an external appointment look like?
These are important questions. But perhaps they come slightly too late in the process.
Before considering who might replace someone, it can be useful to understand exactly what would leave with them.
A job title only tells part of the story
Two people holding the same position can bring very different capabilities to it.
One may have particularly strong customer relationships. Another may hold considerable technical or application knowledge. Someone else may understand the history behind important commercial decisions, know how to navigate a complex internal organisation or have credibility across different functions and geographies.
Much of this will never appear in a job description.
It develops over years of experience: through decisions made, problems encountered, customer conversations, market cycles, projects that succeeded and projects that did not.
That makes succession more complicated than replacing one job title with another.
The role may be replaceable. The accumulated capability can be much harder to replicate.
What would actually leave?
A useful succession conversation therefore starts by looking beyond responsibilities and reporting lines.
If this person left tomorrow, what would the organisation genuinely lose?
It could include customer and supplier relationships, specialist technical knowledge, commercial judgement, understanding of particular markets or applications, leadership credibility, internal networks or knowledge of why previous decisions were made.
Some of those things can be documented.
Some can be transferred.
Others take years to develop.
Identifying the difference early matters.
Internal succession is not simply about readiness for promotion
When organisations look internally for a successor, the obvious question is often whether somebody is ready to move into the position.
A capability-led approach asks something slightly different.
Which elements of the departing person’s capability already exist elsewhere in the organisation?
An internal candidate may not look like a direct replacement on paper but could already possess much of what the business needs. Other areas may be developed through broader responsibilities, mentoring, customer exposure or experience across different functions.
Equally, somebody who appears to be the natural successor by title may still have significant capability gaps.
Understanding those gaps early creates time to do something about them.
Not everything has to sit with one person
There can also be a tendency to search for a replica of the individual who is leaving.
That may not be necessary — or realistic.
A long-serving leader may have accumulated an unusually broad combination of technical knowledge, commercial understanding, customer relationships and organisational experience over many years.
Finding all of that in one replacement can significantly narrow the market.
Instead, organisations can consider which capabilities genuinely need to sit with the successor and which could be distributed across a wider team.
The eventual role may look different as a result.
That is not necessarily a compromise. It may be a better reflection of what the business needs next.
Build, transfer or bring in?
Once critical capability has been identified, the succession question becomes more practical.
What can be developed internally?
What knowledge or relationships need to be transferred while there is still time?
And where does the organisation have a capability gap that may eventually require an external appointment?
The answers will be different for every business.
But having those conversations several years before a likely departure creates considerably more options than beginning when a vacancy becomes imminent.
It can allow potential successors to gain experience they do not yet have, relationships to be transferred gradually and external markets to be understood before there is pressure to make an appointment.
The external market is part of succession planning
Even where the preferred outcome is an internal successor, understanding the external talent market can be valuable.
It helps organisations establish whether the capability they may eventually need is readily available, how competitors structure similar roles, where relevant experience sits and whether expectations around location, remuneration or career background are realistic.
That does not mean beginning a recruitment process years in advance.
It means understanding the alternatives.
Because succession planning becomes much more difficult when a business discovers, close to a departure, that the external profile it assumed would be available is actually scarce.
Succession is ultimately about continuity of capability
There will always be individuals whose departure has a significant impact on an organisation.
The objective of succession planning is not to make people interchangeable.
It is to understand what makes their contribution difficult to replace and to give the organisation enough time to protect what matters.
Sometimes the answer will be developing somebody internally.
Sometimes it will be transferring knowledge or redistributing responsibilities.
Sometimes external capability will need to be brought into the business.
Often it will be a combination of all three.
But the starting point remains the same.
Before asking who will replace someone, understand what you actually need to replace.
Because succession planning may start with a person.
But effective succession planning starts with capability.
