A senior leader can leave with little warning, and the effect can spread across the company within days. Teams may become unsure about key decisions, who speaks with major clients, or who can approve urgent work. The risk grows when too much authority or business knowledge sits with 1 person.
Succession planning reduces that risk before a vacancy appears. It identifies roles that matter to business continuity, finds people who may be able to take them on, and gives those people time to prepare. Companies that want a formal system for this work can also use succession planning software to track critical roles, possible successors, readiness, and development work in one place.
Research shows many employers remain exposed. SHRM found that only 21% of surveyed HR professionals said their organization had a formal succession plan, while 56% reported having no plan at all.Read SHRM’s succession planning guidance SHRM also describes succession planning as work that often takes 12 to 36 months, which makes early preparation important.
Leadership change is common. Spencer Stuart recorded 168 new CEOs across the S&P 1500 during 2025 the highest since 2010 and 60% came from inside their companies.See Spencer Stuart’s 2025 CEO transition research These figures show why companies need time to build internal candidates before an important role becomes vacant.
TL;DR
- Identify the roles where a vacancy would create the greatest business risk.
- Define what each critical role will require in the future, not only what the current role holder does today.
- Build a pool of possible successors and assess each person’s readiness against the actual role.
- Use real development assignments and knowledge transfer to close specific skill, experience, and continuity gaps.
- Include emergency coverage for sudden departures, including important roles below the executive level.
- Review the plan regularly so role priorities, candidate readiness, and development actions stay current.
What Is Succession Planning?
Succession planning is the process of preparing people to take on roles that will matter to the company in the future. It looks at the work each critical role requires and identifies employees who may be able to handle that work later. The process also shows which skills or experiences those employees still need.
CIPD describes succession planning as identifying and growing talent for future leadership and business-critical positions, and connects it with wider talent management. Successor development cannot sit apart from normal employee development. See CIPD’s succession planning factsheet Think about a VP of Sales retiring in 18 months.
Putting 2 names into a spreadsheet gives possible replacements, but not evidence that either can manage forecasts, lead other managers, handle large clients, and make difficult calls during a weak quarter. A useful succession planning process turns those remaining gaps into specific work before the vacancy opens.
Succession Planning and Replacement Planning Solve Different Problems
Replacement planning and succession planning are related, but they answer different business needs. Replacement planning focuses on who can cover a role if it becomes vacant today, while succession planning prepares people for future responsibility over a longer period. Companies usually need both because an urgent vacancy creates a different problem from a planned leadership change.
| Replacement planning | Succession planning |
| Finds short-term cover | Builds future candidates |
| Focuses on an urgent vacancy | Starts before a vacancy appears |
| May name 1 backup | Can keep several options open |
| Uses current job needs | Looks at future job needs |
| Helps keep essential work moving | Builds long-term continuity |
If your CFO left tomorrow, the company would still need someone to approve payments, oversee financial reports, and deal with auditors. Replacement planning keeps those duties moving while leaders decide what happens next.
Succession planning looks further ahead, asking who could become the next CFO and what that person would need to learn before taking the full job, including larger finance duties, board exposure, or decisions the candidate has never owned before.
Why Succession Planning Matters Now
Waiting for a resignation gives leaders less time to prepare and fewer choices. Early planning creates time to test possible successors, move critical knowledge, and bring in outside talent if needed. A critical employee can resign within weeks, while developing a replacement may take months or years, so starting early is essential. The gap between how fast someone can leave and how long it takes to build a capable replacement is the central problem succession planning is designed to close.
Leadership change can happen faster than people can grow
A key person can leave quickly, but a future leader may need years to prepare for a larger role. This timing gap creates risk because strong performance in a current position does not prove readiness for a job with wider duties. The candidate may still need experience with bigger decisions or more complex teams.
Russell Reynolds’ Global CEO Turnover Index continues to track substantial leadership movement across major listed companies. Its H1 2026 findings show boards continue to invest in long-term succession work while placing more weight on prior CEO experience for some appointments. Review the Russell Reynolds Global CEO Turnover Index The details concern large listed companies, but the need to prepare leaders before a vacancy applies much more widely.
Many senior jobs are filled from inside
Internal appointments already fill many senior roles, which makes internal development important.An internal hire already understands the company, its customers, and its history. Early development gives leaders proof that a candidate can handle duties beyond their current role, including identifying high-potential employees with the capacity to take on broader scope.
Key-person risk exists below the top team
Some of the largest succession risks sit below the executive level. A plant manager may know how to solve production problems that few others understand; a senior account lead may hold customer relationships tied to a large share of revenue. A technical expert may understand why older systems work in certain ways. If that knowledge stays with one person, a sudden departure can force the company to rebuild years of context. The same pattern appears in finance teams where one analyst owns the models used for pricing and forecasting, in legal departments where one person holds institutional knowledge of complex contracts, and in operations where a shift supervisor carries the unwritten rules that keep production running smoothly.
Job level should therefore matter less than business impact. Leaders should examine which vacancies could damage customer service, revenue, or core operations. Workforce planning can support this work by helping companies identify talent gaps before they affect operations.
Future roles may need different skills
A weak succession plan looks for someone who resembles the current role holder. A better plan asks what the position will require in the next few years. The next CFO may need stronger systems knowledge, while a future sales leader may need to manage a different sales model or a much larger team.
PwC’s 2026 CEO succession guidance makes a similar point. It recommends looking several years ahead, linking the future leadership profile to business needs, and maintaining a broad candidate pipeline instead of treating succession as a last-minute event.Read PwC’s CEO succession planning guidance PwC also recommends clear ownership and an emergency plan alongside the longer-term process.
Key knowledge can leave with 1 person
Some business knowledge sits in files and systems, but a large amount remains in the minds of employees who have spent years learning how the company really works, including the reason behind unusual client terms or older operating decisions that newer employees do not understand.
Succession planning helps expose those gaps while the current role holder is still available. The company can then record key processes, bring other employees into that work, and begin knowledge transfer through shared client meetings, documented processes, or job shadowing, well before an exit becomes likely.
Career growth becomes clearer
Succession planning can make career growth clearer for employees. A person may know leaders see them as a possible future manager, but they still need to understand which experience will help them get there. Clear development work turns a broad career goal into something concrete to act on.
Employee development can also affect whether people see a future with their employer. Gallup reported in 2025 that employees and leaders still face major barriers to development, with time away from normal job duties being a common problem.Read Gallup’s research on employee development Its research also connects opportunities to learn and grow with better business outcomes, which gives companies another reason to make development part of normal work rather than an occasional course.
Companies can support this work with a connected talent development process that tracks employee growth and development plans over time, making the work visible enough for leaders to see progress and for employees to understand what they are building toward. Being listed as a possible successor should never be treated as a guarantee of promotion.
Which Roles Need a Succession Plan?
Trying to cover every job can make succession planning difficult to maintain. Most companies get more value by focusing on positions where a vacancy would cause real business harm, such as leaders, technical experts, major account owners, or people who hold rare knowledge.
A role should move higher on the list when a 60-day vacancy could hurt customers, revenue, safety, or essential operations. Hard-to-hire positions and roles that take a long time to learn also deserve attention, especially where retirements or planned growth are expected. Positions requiring niche technical expertise or deep institutional knowledge often fall into both categories and should be prioritized early in the process.
What Should a Succession Plan Contain?
A useful succession plan shows where the company has risk and what leaders are doing to reduce it. A few names beside a job title do not show whether those people are ready or what work still needs to happen.
| Plan part | What it should answer |
| Key role | Which job creates serious risk if it becomes vacant? |
| Future needs | What will the job require in the next 2 to 3 years? |
| Candidate pool | Who may be able to grow into the role? |
| Readiness | Who is ready now or still developing? |
| Skill gaps | What does each person still need to learn? |
| Growth work | What task could help close the gap? |
| Knowledge transfer | What know-how or relationships need to be shared? |
| Emergency cover | Who can handle core duties if the role opens tomorrow? |
| Plan owner | Who will keep the plan current? |
The development work inside the plan needs to be specific enough to act on. Writing that someone “needs more leadership experience” gives the manager little direction and gives the candidate no clear test. A better action could be to lead the next budget process and present the outcome to senior leaders. Leaders can review how the employee handled the assignment, which makes later readiness decisions easier to explain.
Companies can use competency management to define the abilities needed for important roles and compare employee skills with those requirements. This can help make development gaps clearer during succession reviews. Managers still need judgment because no score can make the final succession decision by itself.
How to Build a Succession Planning Process That Works
The exact process will change based on company size and leadership needs, but the core work is the same: find critical roles, judge possible successors, and give people the experience they need. A clear process stops succession planning from becoming a yearly exercise where leaders repeat the same names. The difference between a plan that changes behaviour and one that stays in a file usually comes down to whether development work happens between reviews and whether readiness ratings are based on recent evidence rather than reputation.
Deloitte’s research found that 86% of leaders viewed succession planning as urgent or important, while only 14% believed their organization did it well. Read Deloitte’s leadership succession research The research points to the need for clear processes that also account for how leaders and employees behave inside the system.
1. Start with where the business is going
Look at the next 2 to 5 years before reviewing possible successors. Consider planned growth and changes in how the company expects to operate. Those shifts can alter the skills needed in important jobs.
A company moving into new countries may need leaders who have worked across different markets. A business adding new product lines may need managers who can lead through several layers of people. The future direction of the company should shape each critical job profile.
2. Find the roles where a gap would hurt
Create a list of jobs that carry serious business risk if they become vacant. Look at decision power, revenue impact, hard-to-replace knowledge, and the time needed for a new person to learn the work. Salary and title can add context, but they should not decide the list by themselves.
The result may challenge expectations. A pricing analyst can be as hard to replace as a senior sales leader if that analyst owns a model used across every major deal.
3. Define what success in each role will require
Write down what each critical role will need in the future before looking at candidates. Include the main results the person must deliver and the decisions they will own. Add the experience that will matter most as the company changes.
Keep the profile focused on the future role, not the current incumbent. The next leader may need a different skill set because the company will be larger or use different systems, so the profile should reflect those coming changes and include a note about fairness: judging each candidate against the same needs rather than personal preference.
4. Find a pool of possible candidates
Look across the company instead of asking each manager to name only 1 favourite employee. Strong work in the current role matters, but a larger job may require skills the person has never had to show. Use evidence from past projects and work outside the employee’s normal scope.
Some critical roles may have no strong internal candidate. Record that gap rather than adding a weak name to make the chart look complete. An empty pipeline is useful information because it gives leaders time to change hiring or development plans, and a wider pool means more choice when the final decision arrives.
5. Rate readiness against the real job
Use a simple readiness scale that leaders can apply in the same way. “Ready now” can mean the person could take the job with normal transition support. “Ready in 1 to 2 years” can mean the person has a few specific gaps that can reasonably be closed during that period.
Each rating needs evidence behind it. If someone is expected to become ready within 2 years, the plan should explain what needs to happen during those 2 years. A date without clear development work is only a guess. Writing down what the candidate needs and how progress will be checked gives managers something to review and reduces ratings that stay unchanged without reason.
6. Build growth through real work
Formal training can support development, but larger roles are often learned through larger responsibilities. Give candidates assignments that match the gaps found during the review and allow leaders to see how the person performs. The work should teach skills that the future role will actually require.
A future unit head may lead the annual business plan or take control of a large customer issue. A finance candidate may lead lender discussions, while a technical leader could own a major system change. Each task should create evidence that can be used in the next succession review. Current role holders can also accelerate development by sharing the history and decision context that would take years to learn alone.
7. Connect development with performance reviews
Succession decisions should use more than a manager’s opinion about potential. Past performance can show how the candidate handles current responsibilities, while development assignments show how that person handles work closer to the future role. The 2 forms of evidence answer different questions and should be reviewed together.
A connected performance management process can help keep performance history available when leaders discuss successor readiness. Managers can then compare current results with progress on development work. This reduces the chance of succession discussions depending on memory alone. Performance should not, however, be treated as the same thing as potential. Someone can excel in a specialist role without being ready for a management position.
8. Review the plan as things change
Succession plans can become outdated quickly because people leave and jobs change. Some candidates develop faster than expected, while others may decide they no longer want the target role. The company may also create new positions that become more critical than the roles already in the plan.
A formal yearly review is a useful baseline for many organizations. High-risk roles may need more frequent checks during fast growth or major leadership change. The plan should also be updated after any event that changes candidate readiness or the importance of a role. Each review should focus on new evidence, update gaps, and confirm or change the readiness rating based on what has actually happened.
Companies building the process for the first time can use a business succession planning process as a starting framework. The work can begin with a small group of critical roles and expand after leaders learn which parts of the process need more attention. Starting with a manageable scope makes the plan easier to maintain.
Who Owns Succession Planning?
Clear ownership matters because succession plans lose momentum when everyone assumes someone else will manage the work. The board typically owns CEO succession, while senior leaders take responsibility for important jobs within their own areas.
HR usually manages the process and keeps reviews consistent across teams, setting assessment rules and tracking agreed development work. Managers still carry much of the direct responsibility because they control assignments and feedback.
PwC’s guidance describes CEO succession as a full-board responsibility and recommends clear roles for everyone who manages the process. (PwC) The same principle applies lower in the company. Each succession action needs an owner, and the plan becomes more useful when everyone knows who completes the next step.
Common Succession Planning Mistakes
A succession plan can look complete while still leaving the company exposed. The clearest problems usually appear when leaders make assumptions that haven’t been tested.
Treating a name as a commitment
Putting someone on a succession plan doesn’t mean that person will eventually take the role. Business needs can change, the employee may develop differently than expected, or another candidate may become a stronger fit. Treat successor names as current options rather than promised appointments.
Assuming the candidate wants the role
A manager may see an employee as a future leader while that employee has a different career goal. Career discussions need to happen before the company builds important succession decisions around that person. Ask about the employee’s interests and make sure the development work still makes sense for them.
Letting a succession label replace evidence
A candidate can remain on a succession chart for years without getting closer to the role. Readiness should change only when recent work shows that important gaps have closed. If the evidence hasn’t changed, leaders need to reconsider the development plan or the candidate’s readiness.
How Do You Know if the Plan Is Getting Stronger?
Counting names on a succession chart reveals little about how prepared the company really is. Track whether critical roles have credible coverage and whether possible successors are moving closer to readiness. Useful measures include the share of critical roles with at least 1 credible successor, the share with someone ready now, completed development actions, candidate retention, and how often important vacancies are filled internally. These measures should show whether the company has stronger coverage than it had during the previous review.
Metrics should also be reviewed by role risk, not only at company level. A company may report that most critical positions have at least 1 named successor while still carrying serious exposure in the few roles that matter most. If the CFO, plant manager, or head of a major customer account has no credible backup, the overall coverage rate can hide the problem. Leaders should therefore review coverage beside the impact of each vacancy, the time needed to prepare a successor, and the amount of knowledge concentrated in the current role holder.
Readiness movement matters as much as the number of names in the plan. A candidate who has remained “ready in 1 to 2 years” for 3 review cycles may not be developing as expected, or the development plan may not be giving that person the right assignments. Leaders should look for evidence that gaps are actually closing, such as successful project ownership, broader decision authority, exposure to senior stakeholders, or stronger performance in work that resembles the future role. If readiness does not change, the company should revisit the development plan, reassess the candidate, or widen the pool. A useful succession plan becomes stronger when each review produces a clear decision about what changed and what should happen next.
What Succession Planning Looks Like in a Smaller Company
Small companies face the same succession risks as larger ones, and the dependency is often easier to see. A 30-person firm may rely heavily on 1 sales lead or 1 technical expert whose departure could affect a large part of the business at once.
The plan can stay simple and still be useful. Start with positions that would stop important work if they became vacant and decide who could provide temporary coverage. Record key processes while identifying people who could take on more responsibility over time. Smaller companies also need to be realistic: some jobs may have no possible internal successor because the company simply does not employ enough people with the required background, so finding that gap early gives leaders time to recruit or restructure the role.
When Should Your Company Start Succession Planning?
Start as soon as losing 1 person would create a problem that the company could not solve quickly. A known retirement date or planned resignation is not required because the business risk already exists. Waiting for a departure only reduces the amount of time available to prepare.
Several signals mean the company should start sooner. An expected retirement gives a clear reason to act, but concentrated key-person risk can be just as important. Expansion may create larger roles before internal candidates are ready. Some positions also need a long preparation period because successors must build experience they can’t gain quickly. A role with no credible backup deserves early attention even when the current employee has no plans to leave.
Succession Planning Is a Business Continuity Discipline
Every critical role will change hands at some point, even when the exact date is unknown. A working succession plan shows where the business depends heavily on certain people, what leaders are doing to reduce that risk, and gives possible successors time to build the experience they will need.
Start with the roles where a sudden vacancy would cause the greatest problem, define what those jobs will need during the next few years, then identify possible successors and give them work that builds the required skills. That gives leaders better choices when change arrives, protects important knowledge, and shows strong employees a clearer path forward, all while there is still time to prepare.
Frequently Asked Questions
What is succession planning in simple terms?
Succession planning means finding key jobs that the company cannot leave unprepared and helping people get ready to take them on later. It includes identifying possible successors, checking what they still need to learn, and giving them work that builds the required experience. The aim is to prepare before a critical person leaves.
What are the main steps in succession planning?
Start with the future needs of the business and identify roles where a vacancy would cause serious harm. Define what each role will require, find possible candidates, rate their readiness, and assign development work. Add emergency coverage and review the plan as people or business needs change.
What is the difference between succession planning and replacement planning?
Replacement planning focuses on who can cover a job if it becomes vacant now. Succession planning prepares people for future positions over a longer period. Companies often need both because sudden coverage and long-term development solve different problems.
Who is responsible for succession planning?
Business leaders own the main talent decisions, while HR often manages the process and helps keep reviews consistent. Boards usually own CEO succession in companies with formal board oversight. Managers also carry direct responsibility because they give candidates the work and feedback that build readiness.
Does every position need a succession plan?
Every position does not need the same level of succession attention. Start with roles where a vacancy could hurt customers, revenue, essential operations, or major decisions. Jobs that are hard to recruit for or take a long time to learn should also receive closer attention.
How often should a succession plan be reviewed?
A full review once a year is a useful baseline for many companies. Critical positions may need more frequent reviews if the business is growing quickly or going through major change. The plan should also be updated when a candidate leaves or the role itself changes.
Should employees know they are succession candidates?
Employees should have clear career discussions so they understand which development work makes sense for them. Being identified as a possible successor should not be treated as a guaranteed promotion because future needs and readiness can change. The final choice should depend on the facts available when the vacancy occurs.
How far ahead should succession planning begin?
Start early enough to close real skill and experience gaps before the position becomes vacant. SHRM guidance describes succession preparation as a process that often takes around 12 to 36 months. Some senior positions may require more time because candidates need several kinds of experience before they are ready.
What happens if there is no internal successor?
Record the gap instead of forcing a weak candidate into the plan. The company can recruit from outside, hire someone who may grow into the position later, or change how parts of the role are assigned. Finding the gap early gives leaders more time to act.
Why is succession planning important?
Succession planning gives a company more time to prepare for important personnel changes. It helps build future leaders and transfer knowledge before a vacancy appears. It also shows leaders where the business still depends too heavily on individual employees.
