5 Succession Planning Mistakes That Cost Companies Millions

A senior leader leaves the company with little warning. HR and senior management suddenly need answers about who takes over, who owns important decisions, and whether anyone inside the company is ready for the role. A succession plan that looked complete during an annual review can fall apart quickly when a critical position becomes vacant.

The financial impact can grow fast. A poor transition can slow decisions, delay projects, weaken customer relationships, and increase hiring costs. Teams may also spend months operating without clear leadership while the company searches for a permanent replacement.

The cost can become very large at major companies. Harvard Business Review estimated that poor CEO and C-suite transitions erase about $1 trillion in market value each year across the S&P 1500. That figure applies to large public companies, but it shows how much leadership changes can affect business results.

Succession risk exists below the executive level too. A plant manager, sales leader, engineering manager, compliance expert, or operations director can hold knowledge that is difficult to replace quickly. BullseyeEngagement’s succession planning software defines a critical position as a role that has a major effect on operations and is difficult to replace when vacant.

TL;DR

• Succession planning becomes expensive when companies wait for a vacancy before identifying who can take over. Emergency recruiting, delayed decisions, interrupted projects, and lost leadership knowledge can increase the cost of a transition.
• A strong succession plan should be built around the future requirements of each critical role rather than the background or leadership style of the current employee.
• Potential and readiness need separate evaluation. A strong performer may have long-term potential while still needing specific experience before taking responsibility for a larger role.
• Succession information should be reviewed when resignations, promotions, reorganizations, development milestones, or role requirements change. An annual spreadsheet can become outdated quickly.
• Career visibility matters. Employees should understand possible career paths and the experience they need without being promised a specific promotion.
• Companies should identify critical positions, maintain emergency coverage, assess several possible successors, close readiness gaps, and connect development work directly with future role requirements.

Why Succession Planning Failures Become Expensive 

Succession planning should tell leadership where the company is exposed before a resignation happens. Leaders need to know which roles carry the most business risk, who could step into them, and how close each candidate is to being ready. They also need to understand whether the person actually wants the role.

Timing matters because leadership transitions can take much longer than companies expect. SHRM’s succession planning research notes that a new executive may need 12 to 24 months to reach full effectiveness. Waiting until a vacancy appears leaves much less time to build missing experience.

Employees also pay attention to how leadership opportunities are handled. Pew Research Center’s 2024 workplace study found that only 26% of workers were highly satisfied with their opportunities for promotion. Only 37% were highly satisfied with training and skill development.

A weak succession process can therefore create leadership risk while adding retention pressure. The 5 mistakes below show where that risk usually starts and what companies can do before a vacancy exposes it.

1. Waiting Until a Critical Role Becomes Vacant

Many companies start succession planning after the problem has already arrived. A senior employee resigns, HR opens an old organization chart, and leaders begin asking who could take the job. Recruiters may be contacted before leadership has agreed on what the future role actually requires.

This puts the business under pressure from the first day of the vacancy. Leaders have less time to compare candidates or prepare an internal employee. The company may choose the fastest available option because important work can’t remain without an owner.

Time is one of the biggest advantages of starting succession work early. A possible successor may need more experience with budgets, while another may need exposure to larger teams or a different part of the business. Those gaps can often be addressed over several months while the current leader remains in place.

McKinsey’s discussion of CEO succession planning at Prudential provides a useful example. Former Prudential CEO Charles Lowrey described thinking about succession from the beginning of his tenure and working with the board to develop future candidates before the final decision had to be made.

Where the costs begin

The first costs are usually visible. The company may pay an outside search firm, increase recruiter workload, and use hours of senior management time for interviews. An external hire may also require different compensation from an internal promotion.

The wider business cost can be harder to track. If a regional sales leader leaves, the CRO may temporarily take over decisions while sales managers divide important accounts. Forecast ownership can become less clear, while customer issues may take longer to resolve.

One vacancy can therefore consume time across several jobs. Managers may spend hours doing work the former leader handled while also trying to keep their own responsibilities moving. The staffing cost sits beside the operating cost.

BullseyeEngagement’s Talent Match can help leaders identify and rank possible candidates against position needs before the vacancy becomes urgent. The goal is to know where the company has internal options and where it may need outside recruiting.

Use 4 steps before a vacancy happens

1. Identify critical roles. Start with positions where an unexpected vacancy would create serious business disruption.
2. Name emergency coverage. Decide who could keep the work moving for 60 or 90 days if the role became vacant tomorrow.
3. Identify long-term successors. Look at employees who could realistically grow into the position rather than naming someone only because they are nearby.
4. Close readiness gaps. Give potential successors work that builds the experience they still need.

Emergency coverage and long-term succession can involve different people. A peer leader may handle approvals temporarily while a future successor continues developing. This reduces pressure to promote someone before they are ready.

BullseyeEngagement’s guidance on succession planning and career visibility makes the same distinction. Immediate coverage keeps work moving after a sudden exit, while long-term planning prepares the person who may take the job permanently.

Spencer Stuart’s CEO succession planning guidance also stresses preparing for different future scenarios and keeping more than 1 internal option under review. A preferred successor can leave, change direction, or turn out to be the wrong fit.

2. Building the Plan Around the Current Leader

Companies often begin succession discussions by looking for someone who resembles the person currently doing the job. Managers may focus on a similar background, leadership style, or career history because those qualities feel familiar. That can narrow the succession process before the future role has even been defined.

The next leader may face a different job. Growth, acquisitions, new technology, or organizational changes can alter what the position requires. A role that depended heavily on operational experience 5 years ago may now require stronger commercial or digital skills.

The company should therefore define the future version of the role before discussing candidates. SHRM’s succession guidance warns against focusing too heavily on replacing the person instead of understanding what the position will require next.

Familiarity can narrow the candidate pool

Senior leaders naturally notice employees they work with often. People who attend executive meetings or have strong senior sponsors may appear first during succession discussions. Other qualified employees can remain outside that circle simply because they have less exposure.

A narrow candidate pool can cause leaders to repeat familiar career patterns. The company may overlook someone in another division who already has much of the experience the future role requires. That weakens the value of the succession review.

BullseyeEngagement’s Competency Management helps companies map competencies to roles and assess employees against those requirements. Managers can then compare people with the job itself rather than relying mainly on familiarity.

Use these questions before discussing names:

• What work will this role own 2 or 3 years from now?
• Which skills will matter more in the future?
• What experience should a successor already have?
• Which current responsibilities may disappear or become less important?
• Are possible candidates being considered across teams and locations?

Performance and future readiness are different measures

A top performer in the current job can still be a poor fit for the next one. The best salesperson may prefer customer work over managing a team. A skilled engineer may want to stay on a technical path instead of moving into people management.

The future position may also require experience the employee hasn’t had yet. A successful manager might need larger budget responsibility before becoming a VP. Another person may need experience managing work across several business units.

Current performance still belongs in the decision because it shows how the employee has handled existing responsibilities. BullseyeEngagement’s Performance Management tools can provide performance history and appraisal information that supports succession reviews.

The next step is to compare that evidence with the future role. Clear role requirements make development planning easier because managers can point to a specific gap instead of giving broad advice about becoming a stronger leader.

3. Naming a Successor Without Proving Readiness 

A succession spreadsheet can look reassuring because every critical role has 1 or more names beside it. Leadership may interpret those names as evidence that the company has coverage. The real question is whether those people could perform the job if the position became vacant.

Potential and readiness measure different things. Potential suggests that an employee may be able to handle a larger role in the future. Readiness shows how close the person is to performing that role successfully today.

A high-potential employee may still need substantial experience before promotion. Treating that person as “ready now” can create risk for the employee and the business. A readiness label needs evidence behind it.

Give readiness levels clear definitions

Many organizations use labels such as “ready now,” “ready in 1 year,” or “ready later.” Those labels lose value when managers interpret them differently. One manager may reserve “ready now” for someone who could start tomorrow, while another may use it for a person who would need months of support.

A useful rating should tell leaders how close the candidate is to performing the target job. It should also explain what still needs to happen before the person moves into a higher readiness category.

BullseyeEngagement can bring performance records, competency data, Talent Matrix results, manager input, and development progress into succession discussions. Gap information can then show why a candidate received a certain rating.

Career interest belongs in readiness

A person can have the right skills and still have no interest in the role. Companies sometimes spend years preparing an employee without checking whether the job still fits that person’s career goals.

Preferences can change over time. An employee who once wanted management may later prefer a specialist career path. Another person may become interested in a different business area after gaining new experience.

Managers should therefore confirm interest during regular career conversations. Learning that someone no longer wants the target role gives HR time to identify another candidate before a vacancy appears.

Waiting until the promotion is offered creates more risk. The employee may decline at the point when leadership expects an immediate yes, leaving the company to restart the succession search under pressure.

Development must follow the assessment

Recording a skill gap doesn’t prepare anyone. If an operations manager needs more experience with large financial decisions, the person needs work that builds that capability. A note in a succession file changes nothing on its own.

The development action should connect directly to the target role. The employee might lead a larger budget, join planning meetings, or manage a project with broader business impact.

BullseyeEngagement’s Talent Development tools connect employee growth with development plans and ongoing feedback. Managers can track whether the work is actually changing the employee’s readiness.

SHRM raises a similar concern about leadership development spending. Training has more value when it closes a known succession gap instead of becoming a general activity with no connection to future roles.

4. Treating Succession Planning as an Annual Spreadsheet Task 

Annual succession meetings can give leaders a false sense of safety. HR updates a spreadsheet, managers add names, and senior leaders discuss the bench. The file may look current on the day of the meeting.

The information begins aging almost immediately. Employees leave, responsibilities change, and candidates gain new experience. A reorganization can alter what a role requires before the next annual review happens.

A succession plan that isn’t updated can create more risk than leaders realize. A person listed as a successor may have left the company or changed career direction. Another employee may have become ready while the old file still shows them several years away.

The problem is confidence in old information. Leadership may believe a role has coverage because the spreadsheet contains 2 names even though neither option is realistic anymore.

Review succession data when risk changes

The annual review can remain useful, but high-risk positions need additional checks. A critical role with no ready successor deserves more attention than a stable position with several qualified candidates.

Major events should trigger a review too. A resignation, reorganization, promotion, or completed development assignment can change the succession picture immediately. Waiting several months to record that change weakens the plan.

A simple review process can follow these steps:

1. Check critical-role coverage.
2. Confirm candidate interest and employment status.
3. Review changes in readiness.
4. Update development actions and ownership.
5. Record any change in the role itself.

BullseyeEngagement’s Workforce Planning tools can help leaders examine staffing changes and future workforce needs. Succession planning can use that view to identify positions where future changes may create extra risk.

Spreadsheets Can Split the Information Leaders Need

Succession information rarely lives in only 1 file. Performance reviews may sit in another system, competency information may exist elsewhere, and development plans may belong to individual managers. Career goals can be buried in meeting notes.

This makes succession reviews harder because managers have to rebuild the employee’s story from several sources. Different leaders may also arrive with different versions of the same information.

BullseyeEngagement’s article on performance management software for mid-market companies discusses the problems created when employee information is scattered across different places. Succession decisions depend on many of the same signals.

Bringing those signals closer together gives leadership a clearer reason for each readiness rating. It also makes changes easier to see between formal reviews.

5. Keeping Succession Plans Hidden From Future Leaders 

A company can identify the right future leader and still lose that person. This happens when succession planning remains inside HR files and executive meetings while the employee receives no clear information about future opportunities.

Leadership may believe the employee has a career path. The employee may see the same role and responsibilities year after year with no visible sign of progress. That gap can change how outside opportunities look.

Pew Research Center found that only 26% of workers surveyed in 2024 were highly satisfied with their promotion opportunities. Employees who can’t see a realistic path inside the company may take an external opportunity more seriously.

Gallup’s employee turnover research found that 42% of employees who voluntarily left said their manager or employer could have done something to prevent the departure. Gallup also found that 45% had no active discussion with a manager about job satisfaction, performance, or their future during their final 3 months.

Career Visibility Can Stay Practical

Employees don’t need access to private succession rankings. Leadership can keep final appointment decisions confidential while still explaining available career paths and what different roles require.

Managers can discuss the experience an employee needs to build without promising a promotion. A possible successor can learn that a future role requires larger budget ownership or experience leading several teams.

BullseyeEngagement’s Talent Development and Coaching solution supports employee profiles, career pathing, development plans, and coaching. Those tools can connect career discussions with actual development work.

Useful career conversations can cover:

• Roles the employee may want to explore.
• Skills required for those roles.
• Experience the employee still needs.
• Development work available now.
• When progress will be reviewed again.

Hidden Career Plans Can Become a Retention Problem

Consider a director who has delivered strong results for 4 years. Senior leaders see that person as a possible future VP, but the employee has never been told what experience would help them reach that level.

Another company offers the director a larger job and explains the responsibilities, compensation, and path forward. The outside opportunity feels concrete because the employee can see what comes next.

The internal opportunity may exist only in leadership discussions. When the director resigns, executives may feel surprised even though the employee never had enough information to see a future inside the company.

A regular career conversation could have exposed that gap earlier. It could also have shown whether the employee actually wanted the VP role or preferred another direction.

What a Stronger Succession Process Looks Like 

The 5 mistakes above often begin with disconnected information. Leaders may know which roles are important without knowing who is ready to fill them. They may also know who has potential while having little evidence about the development that person still needs.

Research from the Center for Creative Leadership treats succession planning as an ongoing leadership pipeline issue. Future role requirements, leadership development, and transition planning need to remain connected before a vacancy occurs.

A stronger process starts with business risk. Identify the roles where a vacancy would create serious disruption, then define what those positions will require in the future. Candidate discussions should begin after those requirements are clear.

From there, the process can follow 5 steps:

1. Identify critical positions. Focus first on roles with high business impact and high replacement difficulty.
2. Define future role requirements. Document the skills and experience the next version of the job will need.
3. Assess possible successors. Review performance, competencies, career interest, and current readiness.
4. Assign development work. Connect each meaningful gap with experience that can help close it.
5. Review when conditions change. Update the plan after resignations, promotions, reorganizations, or major development milestones.

BullseyeEngagement’s succession planning tools support several parts of this process. Talent Match and Competency Matching can help identify candidates, while the 9-Box Talent Matrix gives leaders another view of performance and potential.

The Leadership Matrix can add information about future leadership readiness. Individual Development Plans can then connect candidate gaps with specific development work, while the Talent Card brings employee information into a single view.

Questions to Ask About Your Succession Process 

A company can test the quality of its succession plan without starting with a large project. A short review of critical roles can reveal where the information is current and where leaders are relying on assumptions.

BullseyeEngagement also provides a succession planning checklist that can support this review. Weak answers point to places where the company may need better coverage, clearer readiness rules, or stronger employee development.

Use these questions with HR and business leaders:

• Which roles would cause the most disruption if they became vacant this month?
• Does each critical role have short-term emergency coverage?
• Which important roles have no strong internal successor?
• What does “ready now” mean inside the company?
• Can managers explain the evidence behind each readiness rating?
• When was each serious candidate last reviewed?
• Has the employee confirmed interest in the target career path?
• Does each major skill gap have a development action?
• Can leaders see succession risk without checking several spreadsheets?
• Do employees understand what they need for future roles?
• Which readiness ratings changed during the last quarter?
• Which critical roles have become harder to replace?

The company doesn’t need to fix every gap at once. Start with roles that carry the greatest business risk and work outward from there. That gives HR a clearer way to show leadership where action is most urgent.

How BullseyeEngagement Supports Succession Planning 

BullseyeEngagement brings several parts of succession planning into the same talent-management environment. Its succession tools help companies identify critical positions and possible successors while giving managers more information about candidate fit.

Talent Match and Competency Matching can support candidate review. The 9-Box Talent Matrix gives leaders a view of performance and potential, while the Leadership Matrix adds information about leadership readiness.

Individual Development Plans can connect succession decisions with employee growth. Managers can record what a candidate needs to work on, assign development activity, and review whether that work changes readiness over time.

The Talent Card can also bring competency information, matrix placement, risk data, development plans, succession candidacy, and gap information into one place. This gives leaders more context without rebuilding the candidate’s history from several files.

Fix Succession Gaps Before a Vacancy Exposes Them 

A resignation often reveals problems that already existed. The company may lack emergency coverage for a critical role, or the preferred successor may still have major skill gaps. An old succession file can hide those weaknesses until leadership suddenly needs an answer.

Companies can address many of these issues while current leaders are still in place. They can identify critical roles, test readiness with real evidence, and give future leaders useful development work. Regular career conversations can also show whether candidates still want the roles being discussed.

BullseyeEngagement’s Succession Planning solution gives HR teams and leaders a central place to identify critical positions, assess candidates, review gaps, and connect succession work with employee development. That can make succession risk easier to see before it turns into an urgent vacancy.

The best time to find a succession gap is while there is still enough time to close it. Better preparation gives leadership more options during a transition and gives employees more time to build the experience future roles require.

Frequently Asked Questions 

What is succession planning?

Succession planning is a process for preparing people to fill important roles in the future. It starts by identifying jobs that matter to business continuity. It then looks at possible successors, their readiness, and the development they still need.

BullseyeEngagement describes succession planning as identifying and developing employees for future critical positions. The process can help reduce leadership gaps when people leave or move into new jobs. It can also help companies build a stronger internal talent pipeline.

What is a critical position?

A critical position is a job that would be hard for the company to leave empty. The role may have a major effect on customers, revenue, operations, or key decisions. It may also require knowledge or skills that are hard to replace.

The position does not have to be an executive role. A technical specialist or experienced manager can also hold critical knowledge. Companies should judge the role by business impact and replacement difficulty.

How many successors should a critical role have?

There is no single number that works for every company. The right level of coverage depends on the importance of the role and the available talent. A company should avoid relying on only one person when the business risk is high.

One candidate can leave or change career goals. The person may also fail to develop as expected. Having more than one possible successor gives the company more options.

What is the difference between potential and readiness?

Potential means an employee may be able to handle a larger role in the future. Readiness shows how prepared that person is today. A high-potential employee can still have several gaps before they are ready.

Managers should review both factors. Potential helps identify people worth developing. Readiness helps leaders judge whether someone can take the role soon.

How often should succession plans be reviewed?

The review schedule should match the level of risk. Critical roles with weak coverage should be checked more often. Stable roles with several strong candidates may need less frequent review.

Major events should also trigger an update. A resignation, reorganization, promotion, or major development step can change succession risk. Waiting for the next annual meeting may leave the plan outdated.

Should employees know they are succession candidates?

Companies should give employees enough information to understand career paths and development needs. Managers can talk about possible future roles without making a promise. This helps employees see what they can work toward.

Some succession details may still need to stay private. Specific candidate rankings can change as business needs change. The company can protect those decisions while still giving employees useful career guidance.

Can succession planning help reduce turnover?

Succession planning can support retention when employees can see real growth paths inside the company. Career discussions can show people what roles may be available and what they need to learn. This can make an internal future feel more real.

It does not solve every retention problem. Pay, management quality, workload, and personal goals still matter. Succession planning can still address one common reason people leave: a lack of visible career growth.

Why do succession plans fail?

Succession plans often fail because leaders start too late or work with old information. They may also choose candidates based on opinion without enough evidence. Development work may then stop after the annual review.

Plans can also fail when the chosen employee does not want the target role. A company may spend years preparing the wrong person. Regular career talks and current readiness data can reduce that risk.

What should succession planning software include?

Useful succession software should show critical positions and possible successors. It should also help leaders review readiness, competencies, development progress, and risk. Managers need enough information to understand why a candidate is being considered.

The system should also be easy to update. Old information can create false confidence. Current data gives leadership a better view of real succession coverage.
