Succession planning can identify the people who might step into key roles in the future. It doesn't, by itself, make them ready to do so.
That is where mentoring and succession planning fit naturally together.
A succession plan may identify high-potential employees, future leaders and roles where continuity matters. Mentoring gives those people access to experience they have not yet had time to build for themselves: difficult decisions, organisational context, leadership judgement and the lessons learned from getting things wrong as well as getting them right.
Rather than waiting until someone is promoted and expecting them to grow into the role under pressure, mentoring can start that development much earlier.
For organisations already using leadership mentoring, succession planning provides one of its clearest applications: developing a stronger pipeline of people who are better prepared when opportunities or leadership vacancies arise.

How mentoring and succession planning work together
Succession planning is sometimes treated as an exercise in identifying replacements: if this person leaves, who takes their place?
Useful succession planning goes further.
It asks whether the organisation has people with the potential to take on greater responsibility, what development they need before they are ready, and how vulnerable the organisation would be if an important person or capability disappeared unexpectedly.
Mentoring helps address the development part of that equation.
A mentor can give a high-potential employee access to someone who has already dealt with the kinds of situations they are likely to face later in their career. That might include leading people for the first time, managing competing priorities, dealing with senior stakeholders, making decisions with incomplete information or understanding how different parts of the organisation affect one another.
Formal training can teach leadership principles. A good mentor can add the context of what those principles look like when real people, pressures and consequences are involved.
Developing high-potential employees through mentoring
Identifying high-potential employees is only useful if something happens next.
Simply labelling somebody as having potential can even create problems if the organisation then leaves their development largely to chance.
Mentoring provides a way to turn potential into preparation.
For a high-potential employee, a mentor can help them:
- understand what a more senior role actually involves rather than simply what its job description says
- recognise gaps in their own experience or judgement
- explore situations they have not encountered before
- develop greater confidence in making decisions
- understand the wider organisation beyond their current role or department
- learn from somebody else's successes and mistakes
- build the interpersonal and leadership skills needed for greater responsibility
- reflect on whether the next step being considered is actually right for them
This last point matters.
Succession planning should not simply be about moving apparently capable people upwards. A mentoring relationship gives an employee a relatively safe place to explore what they want, what they are suited to and what further experience they may need before taking on a particular role.
That can result in a better-prepared successor. Occasionally, it can also reveal that a different development path would be better for both the individual and the organisation.
Succession planning is about readiness, not just potential
There is an important distinction between somebody who could perform a senior role eventually and somebody who could step into it next month.
Strong succession planning needs to understand that difference.
An employee may have excellent technical ability and obvious leadership potential but little experience of managing people. Another may be an effective manager but have had limited exposure to strategic decision-making. Someone else may understand their own department extremely well but know very little about how the wider organisation operates.
Those are development gaps rather than reasons to discount somebody.
Mentoring can help make those gaps visible early enough to do something about them.
The mentor does not need to turn the mentee into a copy of themselves. Their value is in helping the individual think through unfamiliar situations, challenge assumptions and develop the judgement they will need when responsibility increases.
That is one of the reasons mentoring works particularly well alongside succession planning: development can happen gradually, while the employee is still able to test their thinking before the consequences become much larger.
Passing organisational knowledge to future leaders
Some of the most valuable knowledge inside an organisation is never written down.
Policies, processes and systems can be documented. Experience is harder to capture.
Experienced employees often know why a particular process exists, which relationships matter, where previous attempts have failed, which risks are easy to underestimate and how the culture of an organisation affects what works in practice.
When somebody leaves, much of that knowledge can leave with them.
Mentoring creates a route for organisational knowledge to move between people before that happens.
For succession planning, this can be particularly valuable when someone is being prepared for a role currently held by a much more experienced employee. Their mentor does not necessarily need to be the person they might eventually replace - and there can be good reasons why they should not be - but access to relevant organisational experience can make the eventual transition far less abrupt.
This is also one area where experienced employees approaching retirement can still play an extremely useful role. Where they have the aptitude and desire to mentor, they can help pass on years of experience without succession becoming a rushed handover during somebody's final few weeks.
Should mentors help identify high-potential employees?
Mentors can provide useful insight into how somebody is developing, but mentoring and selection should not become the same process.
A strong mentoring relationship depends upon trust. Mentees need to be able to discuss uncertainty, mistakes and areas where they are struggling without feeling that every conversation is secretly part of an assessment.
For that reason, decisions about who enters a succession pipeline should normally use clear organisational criteria and evidence from more than one source.
Once people have been identified for development, however, mentors can be extremely valuable in helping them understand their strengths, expose blind spots and prepare for increasing responsibility.
The distinction is important: succession planning identifies the development need; mentoring helps the individual work on it.
Choosing mentors for succession planning
The most senior person available is not automatically the best mentor.
The right match depends upon what the potential successor needs to develop.
Relevant experience may matter. So might knowledge of a particular profession, sector or organisational environment. But personality, communication style, availability and the mentor's willingness to listen are just as important.
There can also be real value in matching beyond the obvious choice.
Someone from another department may help a future leader develop a more organisation-wide perspective. A mentor outside the mentee's direct reporting line may make more candid conversations possible. An external mentor may provide challenge without internal politics affecting the relationship.
The question is not simply, “who has done this job before?” It is, “who has the experience and perspective this person needs next?”
Getting those decisions right becomes increasingly important when mentoring moves beyond a handful of individual relationships and becomes part of a structured succession programme. Our guide to designing a mentoring programme looks at the wider decisions around programme structure, matching, engagement and evaluation.
Mentoring develops more than future job skills
People preparing for more senior roles rarely need only technical knowledge.
As responsibility increases, judgement, communication, influence, confidence and the ability to work through other people become increasingly important.
These are difficult things to develop entirely through courses because they are exercised in situations rather than learnt as isolated information.
Mentoring allows somebody to bring those situations into a continuing conversation.
They can discuss a difficult meeting before it happens, examine why a decision did not produce the expected result, explore different ways of handling a colleague or stakeholder and return later to consider what happened.
Over time, the employee is not simply accumulating advice. They are developing their own way of thinking.
That is one reason coaching and mentoring can complement more formal learning and development rather than competing with it.
Building mentoring into a succession plan
Mentoring is most effective when it is connected to what the organisation is actually trying to achieve.
If succession planning has identified roles where future capability is important, the mentoring programme can be designed around those needs. That might involve:
Identifying succession priorities
Which roles, capabilities or areas of leadership present the greatest continuity risk?Identifying people for development
Who has the potential and appetite to take on greater responsibility, either soon or over the longer term?Understanding development gaps
What experience, knowledge, leadership capability or organisational exposure does each person need?Matching mentors around those needs
Select mentors because they can contribute to that development, rather than simply because they are senior.Setting useful development goals
Give the relationship direction without turning mentoring into another performance-management exercise.Reviewing progress Succession plans change
People develop, roles change and organisational priorities move. Mentoring and succession planning should be able to change with them.
This does not mean every mentoring conversation needs to be monitored by HR.
Quite the opposite. The organisation needs enough visibility to understand whether its programme is working while preserving enough privacy for genuine mentoring relationships to develop.
Using mentoring software for succession planning
A small number of mentoring relationships can be managed informally.
Once an organisation wants to connect larger numbers of high-potential employees with suitable mentors, the administrative challenge becomes much greater.
Matching people manually, keeping track of relationships, encouraging participation, monitoring progress and understanding whether the programme is working can quickly become difficult to manage through spreadsheets and email.
A dedicated mentoring platform can provide the structure around those relationships without trying to replace the relationships themselves.
For succession planning, that can mean matching people according to the capabilities or experience they need to develop, supporting structured mentoring journeys, monitoring engagement and giving programme managers a clearer view of how the initiative is progressing.
CASE STUDY: PLADIS
pladis built its succession planning aims into a phased rollout rather than trying to launch everything at once: a general mentoring platform first, then graduate, function-specific and location-specific programmes layered in as the initiative matured. That structure let the organisation extend mentoring across 16,000+ employees in 27 bakeries across 11 countries without losing sight of individual programme objectives.
“We are pleased to report that all objectives are being successfully achieved. Since collaborating with our Europe and Developing Markets region, we have observed a significant increase in the culture of mentoring. Cross-regional mentoring relationships are flourishing, with positive feedback highlighting how having a mentor from a different region offers fresh perspectives on both professional and personal matters.”
- Kelly Green, Learning and Development Business Partner, pladis
The objective is not to automate succession planning. It is to make mentoring practical at the scale required to support it.
Building a stronger succession pipeline
No organisation can predict every vacancy, departure or future leadership requirement.
It can prepare for them.
Mentoring and succession planning work well together because they address two different parts of the same problem. Succession planning looks ahead at the people and capabilities an organisation may need. Mentoring helps today's employees develop towards those future responsibilities.
Done well, the result is not simply a list of possible successors.
It is a stronger pool of people who have had time to build their judgement, broaden their experience, learn from people further ahead and become better prepared for whatever role comes next.
FAQ
Does mentoring actually help with succession planning, or is it just general professional development?
Succession planning identifies who might be ready for greater responsibility and where the gaps are. Mentoring is one of the most direct ways to close those gaps, because it gives someone access to judgement and experience they can't yet get from their own role. The two work as a pair rather than as substitutes for each other.
Can mentoring software support a succession planning programme?
Yes. Once a succession programme involves more than a handful of relationships, matching people manually and tracking progress by spreadsheet becomes hard to sustain. A mentoring platform handles the matching, the ongoing relationship tracking and the reporting, so programme managers can see whether development is actually happening across the pipeline rather than relying on informal updates.
How does mentoring connect high-potential employees with future leadership opportunities?
By giving them structured access to people who've already faced the situations they're being prepared for - difficult decisions, senior stakeholders, unfamiliar parts of the organisation. That exposure is hard to get from training alone, and it's what turns being identified as having potential into genuine readiness.
Who should mentor someone in a succession pipeline?
Not automatically the most senior person available. The right mentor depends on what the successor actually needs to develop - that might be a specific type of experience, a different department's perspective, or simply someone outside their reporting line who can have franker conversations. Seniority helps, but it isn't the deciding factor.
How do I choose a mentoring platform to support succession planning at scale?
Look for a platform that can match people against the specific capabilities or experience gaps identified in your succession plan, rather than generic mentor-mentee pairing, and that gives you visibility into engagement and progress without turning every mentoring conversation into a monitored process. PLD's mentoring platform is built around exactly that structure - support the relationships without policing them.
