Succession planning is often associated with identifying a replacement for a chief executive or another senior leader. But effective succession planning involves much more than maintaining a confidential list of potential replacements…
Organisations also need to protect critical skills, develop future leaders, retain institutional knowledge and prepare for workforce changes that may be difficult to predict.
A long-serving specialist approaching retirement may hold expertise that is difficult to replace. A high-performing manager might have the potential to take on a broader leadership role but lack the experience required to do so immediately.
Meanwhile, a business may discover that several critical positions depend on the same small group of individuals.
The Chartered Institute of Personnel and Development (CIPD) defines succession planning as identifying and developing talent to fill leadership and business-critical positions in the future.
For HR leaders, the challenge is choosing the right combination of assessment, talent development and workforce planning solutions to make that process reliable.
The objective isn’t simply to know who might replace someone. It’s to ensure the organisation is ready when change happens.
At a Glance: What HR Teams Should Compare
| Area to assess | Why it matters | What to check |
|---|---|---|
| Critical roles | Identifies where departures would create the greatest risk | Business impact, specialist skills and dependencies |
| Leadership potential | Helps identify future capability beyond current performance | Assessment quality, role fit and fairness |
| Succession readiness | Distinguishes possible successors from those ready to move | Experience gaps, readiness criteria and development plans |
| Knowledge transfer | Protects expertise when experienced employees leave | Mentoring, documentation and transition arrangements |
| Talent development | Turns potential into practical capability | Stretch assignments, coaching and internal mobility |
| Governance and reporting | Keeps plans fair, current and actionable | Confidentiality, ownership, review cycles and success measures |
Identify the Roles That Matter Most
Succession planning should begin with the roles most critical to an organisation’s performance and resilience.
These are not necessarily its most senior positions.
A specialist technical employee, experienced operational manager or individual responsible for a major customer relationship may be difficult to replace.
The CIPD recommends identifying business-critical positions before deciding how succession arrangements should operate.
HR teams should work with business leaders to assess which roles would create significant disruption if they became vacant.
This involves considering the availability of suitable replacements, the expertise required and how quickly somebody else could assume responsibility.
The aim should be to prioritise genuine business risk rather than automatically include every management position.
Assess Potential Rather Than Current Performance Alone
One of the most common succession planning mistakes is assuming that the best-performing employee will become the best leader.
Strong performance in an existing role is valuable, but a more senior position may require different capabilities.
A successful technical specialist, for example, may need to develop commercial judgement, people leadership or strategic decision-making before taking on a broader role.
Saville Assessment provides talent and leadership assessment tools designed to identify potential, strengths and development requirements.
Its Leadership Potential Dashboard supports succession planning by presenting information about leadership potential and readiness across groups of employees.
HR teams should consider whether proposed assessment solutions evaluate the capabilities required for future roles rather than simply current performance.
The objective is to identify who could succeed with appropriate development, not just who is performing well today.
Distinguish Readiness from Potential
Identifying somebody with leadership potential does not mean that they are ready to take on a critical role immediately.
Succession plans should distinguish between individuals who could step into a position now and those who may become suitable after further development.
This distinction helps organisations understand where capability gaps remain.
Saville Assessment’s leadership assessment capabilities can support evaluations of potential across different types of leadership responsibility, including operational, people and strategic leadership.
However, assessment results should be considered alongside relevant experience, performance evidence and individual aspirations.
A person may have the capabilities required for a future role but no interest in pursuing that career path.
Succession planning should therefore include meaningful career conversations rather than assume that identified employees will automatically accept new responsibilities.
Avoid Relying on Familiar Names
Traditional succession planning can be influenced by visibility and personal relationships.
Senior leaders may nominate employees they know well, while talented individuals in less prominent teams receive limited consideration.
This can create unnecessary risks and restrict opportunities for development.
HR leaders should establish consistent criteria for identifying potential successors.
Structured assessments, evidence from different managers and appropriately designed talent reviews can help challenge assumptions.
Saville Assessment’s tools are designed to provide comparable leadership potential data across employee groups, supporting more evidence-based decisions.
However, no assessment should be treated as an unquestionable verdict.
Organisations should examine how tools have been validated, whether they are appropriate for their workforce and how human judgement contributes to final decisions.
A succession plan should identify the strongest future candidates, not simply the most familiar names.
Include Late-Career Talent in Workforce Planning
Succession planning is sometimes approached as a process of identifying younger employees to replace older colleagues.
That can overlook the continued value and ambitions of experienced workers.
Employees approaching traditional retirement ages may wish to continue working, change responsibilities, develop new skills or move into more flexible arrangements.
The ‘R’ Zone specialises in helping organisations recognise and retain the contribution of late-career employees while supporting effective workforce transitions.
Its services include assessments of workforce practices, leadership support and structured conversations about later-career development.
For HR teams, the priority should be to understand individual circumstances and aspirations rather than make assumptions based on age.
Effective succession planning should create opportunities for people at different career stages while protecting the organisation against avoidable capability loss.
Protect Institutional Knowledge
The departure of an experienced employee can create problems that are not immediately apparent from a job description.
They may possess detailed knowledge of customers, processes, systems or organisational history that has never been formally documented.
Replacing the position does not necessarily replace that expertise.
HR teams should therefore consider knowledge transfer as part of succession planning.
This may involve mentoring, documenting essential processes, sharing responsibilities or creating opportunities for potential successors to work alongside experienced colleagues.
The ‘R’ Zone’s approach to late-career workforce management includes capability retention and structured transitions.
These capabilities are relevant to organisations concerned about the loss of expertise as workforce demographics change.
Knowledge transfer should begin before departure becomes imminent.
A successor cannot learn everything important during a short handover period.
Turn Succession Plans into Development Plans
Identifying potential successors creates little value unless organisations help them become ready.
The CIPD emphasises the importance of relevant work experience and tailored development within succession programmes.
This may involve stretch assignments, secondments, mentoring, coaching or opportunities to lead projects outside an employee’s current responsibilities.
The development required should reflect the future role.
An employee preparing for a senior operational position may need experience managing larger teams or budgets.
Another moving towards strategic leadership might benefit from exposure to board-level decisions and cross-functional responsibilities.
Saville Assessment provides individual development information linked to leadership potential, which can help organisations identify appropriate development priorities.
The objective should be to close specific readiness gaps rather than simply provide additional training.
Consider Internal Mobility
Succession planning does not always require a direct promotion.
An employee may benefit from moving into another function, managing a different team or taking on a specialist assignment before progressing further.
These experiences can help develop broader organisational knowledge and leadership capability.
They may also reveal individuals whose potential would otherwise remain unnoticed.
HR teams should examine whether their talent management systems support visibility across departments.
A strong potential successor in one business unit may be relevant to a critical position elsewhere.
However, internal mobility requires coordination.
Managers should not be encouraged to retain talented employees simply because moving them would create a short-term inconvenience.
A successful succession strategy considers the organisation’s wider capability rather than individual departmental interests.
Plan for Unexpected Departures
Not every vacancy provides months of advance warning.
Resignations, illness, sudden business changes and other circumstances can leave critical positions unfilled unexpectedly.
Organisations should therefore distinguish between emergency cover and longer-term succession development.
Emergency arrangements may identify somebody who can temporarily assume essential responsibilities.
Longer-term planning focuses on preparing individuals to perform the role effectively on a permanent basis.
These are related but different requirements.
HR leaders should establish which critical positions have suitable interim cover and where the organisation remains particularly exposed.
The aim should be to maintain business continuity while allowing time for appropriate permanent decisions.
Make Succession Conversations Constructive
Succession planning can be sensitive.
Employees may worry that discussions about future roles signal an intention to replace them.
Others may feel disappointed if they are not identified as potential successors.
Late-career conversations can be particularly difficult when managers make assumptions about retirement or future working preferences.
The ‘R’ Zone provides manager development through its R-Frame approach, helping organisations manage late-career and succession-related conversations more confidently.
HR teams should establish clear principles for discussing career aspirations, development opportunities and workforce transitions.
Employees should be supported to make informed decisions about their own futures.
Succession planning should not become a mechanism for pressuring individuals to retire or move aside.
Evaluate Assessment Fairness and Data Protection
Talent assessments can provide useful evidence, but they also involve collecting and analysing information about employees.
HR teams should understand which data is collected, how results are interpreted and who can access them.
The Information Commissioner’s Office (ICO) provides guidance on profiling and automated decision-making involving personal information.
Where organisations use automated tools to support significant employment decisions, they should assess the applicable data protection requirements and ensure appropriate safeguards.
Buyers should also ask assessment providers about validation, accessibility and fairness across different employee groups.
Clear criteria and meaningful human oversight are important.
Assessment technology should support better decisions, not create unexplained barriers to advancement.
Choose the Right Combination of Solutions
Succession planning providers do not all address the same problem.
Some offer psychometric assessments, leadership potential analysis and talent dashboards.
Others focus on leadership development, career transitions, knowledge retention or strategic workforce planning.
Saville Assessment is particularly relevant to organisations seeking structured evidence about leadership potential and readiness.
The ‘R’ Zone brings a complementary focus on late-career workforce engagement, capability retention and transition planning.
HR teams should establish which gaps exist in their current approach before comparing suppliers.
An organisation with effective talent identification but weak knowledge-transfer arrangements may need a different solution from one that lacks reliable methods of assessing future leaders.
The objective should be a coherent succession process rather than purchasing disconnected tools.
Measure Bench Strength and Succession Progress
A succession plan should provide a realistic picture of organisational readiness.
Useful measures may include the proportion of critical roles with identified successors, the number of individuals considered ready for advancement and progress against development objectives.
Organisations can also examine whether internal appointments succeed and whether capability gaps are becoming smaller over time.
However, simply assigning a name to every critical role does not demonstrate resilience.
A plan may appear complete while nominated individuals remain unprepared, unwilling or unavailable.
HR leaders should therefore review the strength of the succession pipeline, not just the existence of succession records.
Keep Plans Current
Succession planning cannot be completed once and left unchanged.
Business priorities evolve, employees develop new capabilities and individuals’ career aspirations change.
A potential successor identified two years ago may no longer be the most appropriate candidate.
Equally, emerging talent may have developed sufficiently to become ready for greater responsibility.
The CIPD recommends keeping succession arrangements aligned with organisational needs and reviewing them as circumstances change.
HR teams should establish appropriate review cycles and make sure managers take responsibility for updating information.
Plans should also respond to restructuring, new technology, changes in strategic direction and emerging skills requirements.
A succession plan is only useful if it reflects the organisation that exists today and the one it expects to become.
