Most succession plans are not really plans. They are lists: a spreadsheet of names next to roles with a readiness rating that nobody looks at until a crisis forces the question. Real succession planning develops leaders over years, tests them in progressively complex roles, and builds the organizational depth that means no single departure threatens the institution’s continuity. This guide explains how to do it properly.
Succession planning is the process of identifying and developing internal talent to fill critical leadership positions when they become vacant. Done well, it ensures organizational continuity, reduces dependence on external hiring for senior roles, accelerates leadership development, and signals to high-potential employees that the organization invests in their futures. Done poorly, or not at all, it leaves organizations chronically exposed to leadership transitions that could have been managed.
For HR professionals, senior leaders, and board members, succession planning is a strategic responsibility, not an administrative one. The quality of an organization’s leadership pipeline is a material factor in its long-term performance and resilience.
Key Takeaways
Effective succession planning identifies critical roles, assesses current talent against future requirements, creates individual development plans for high-potential employees, and tests readiness through stretch assignments. SHRM research indicates that organizations with formal succession planning processes fill leadership vacancies 20% faster and report significantly higher employee engagement among high-potential staff. The 9-box talent grid is the most widely used assessment tool, but it requires calibrated application to avoid common biases.

Why Succession Planning Fails: The Common Patterns
Planning for roles rather than capabilities: Succession plans that identify “a successor for the CFO role” without defining what capabilities the next CFO will need to handle the organization’s future challenges produce candidates who are ready for the role as it was, not as it will be. The first step in succession planning is understanding what the critical roles require in three to five years, not just today.
Confusing performance with potential: The most common succession planning error is treating high performers as automatically high-potential leaders. Strong individual contributors often lack the mindset, motivation, or capability to succeed in leadership roles that require fundamentally different skills. The 9-box grid exists specifically to separate the two dimensions, but it requires calibrated assessment rather than ratings inflation.
No development action: A succession plan without funded, time-bound development actions is a document, not a plan. Identifying someone as a succession candidate without providing the stretch assignments, coaching, and development investments that actually build readiness produces a false sense of preparedness that collapses when a real vacancy occurs.
Lack of diversity in the pipeline: Succession pipelines that consistently reflect the demographic profile of current leadership rather than the available talent pool are both a fairness issue and a strategic risk. Organizations that draw from a narrow talent pool miss perspectives, capabilities, and market understanding that diverse leadership provides. Pipeline diversity requires active management, not passive observation.
The Succession Planning Process
Identify Critical Roles
Not every role requires formal succession planning. Critical roles are those whose vacancy would significantly disrupt organizational performance or strategic execution, and where external hiring cannot quickly or adequately fill the gap. These typically include the CEO, direct reports to the CEO, and specialized technical or operational leaders with rare skills or institutional knowledge. Regulatory requirements may also define certain roles as requiring succession plans.
Define Future Role Requirements
Assess what each critical role will require in three to five years given the organization’s strategic direction. This step is frequently skipped, producing succession plans that prepare candidates for the role as it is today rather than what it will need to be. Strategic context, technology change, regulatory evolution, and market dynamics all shape future leadership requirements.
Assess Current Talent Against Future Requirements
Use a structured assessment process to evaluate potential successors against the defined future role requirements. The 9-box grid (plotting performance against potential) is the most widely used tool. Assessment should draw on multiple data sources: performance reviews, 360 feedback, assessment centre outputs, and direct observation, not just manager nominations. Calibration sessions across managers reduce rating inconsistency and individual bias.
Create Individual Development Plans
For each identified high-potential employee, build a specific development plan tied to the gaps between their current profile and the target role requirements. Development plans should include stretch assignments (the most powerful development intervention), formal learning, mentoring or coaching from experienced leaders, and cross-functional exposure. Our guide on enhancing leadership communication covers one of the core capabilities most succession candidates need to develop.
Test Readiness Through Experience
A succession candidate is not ready until they have been tested in conditions that approximate the target role’s demands. Interim leadership assignments, project sponsorship, board or committee participation, and cross-functional leadership responsibilities are the proving grounds that distinguish genuine readiness from theoretical capability. For organizations with dispersed or remote operations, succession candidates also need exposure to leading across geographies and virtual environments, an area covered in our guide on managing remote teams.
Review and Update Regularly
Succession plans become stale quickly. People leave, change roles, or develop faster or slower than anticipated. Business strategy shifts alter the capabilities required in critical roles. Succession plans should be reviewed at minimum annually as part of the talent review cycle and updated whenever significant organizational or strategic changes occur. A succession plan that has not been reviewed in two years is almost certainly wrong.
The 9-Box Talent Grid: How to Use It Properly
| Box Position | Profile | Development Priority |
|---|---|---|
| High Performance / High Potential (Top Right) | Stars: delivering strong results and demonstrating the capability and motivation to grow into significantly larger roles | Accelerated development, stretch assignments, succession pipeline priority, retention investment |
| High Performance / Moderate Potential (Middle Right) | Strong contributors: excellent in current roles, likely to move one level up but not to the most senior leadership positions | Lateral development, role enrichment, technical deepening, retention focus |
| High Performance / Low Potential (Bottom Right) | Specialists and experts: outstanding at current level, at or near their ceiling | Recognition, compensation alignment, technical career paths, avoid forced promotion |
| Moderate Performance / High Potential (Top Middle) | Emerging talent: strong growth trajectory, currently underperforming relative to potential due to role fit, experience, or development gaps | Coaching, role adjustment, targeted development investment, patience |
| Low Performance / High Potential (Top Left) | Enigmas: significant gap between demonstrated results and assessed potential. Usually indicates role mismatch, personal circumstances, or inflated potential assessment. | Investigate root cause before investment; role change or coaching depending on diagnosis |
| Low Performance / Low Potential (Bottom Left) | Poor fit: not performing and no evidence of growth trajectory | Performance management, role change, or exit |

Frequently Asked Questions
How is succession planning different from workforce planning?
Workforce planning addresses the organization’s overall talent supply and demand: how many people with what skills are needed, and how to source them. Succession planning is a subset focused specifically on critical leadership roles and the pipeline of internal candidates prepared to fill them. Workforce planning is broader in scope; succession planning is deeper in its focus on individual development.
Should succession plans be shared with candidates?
This is one of the most debated questions in succession planning practice. The case for transparency is that it enables candidates to engage actively in their development and signals the organization’s investment in them. The case for confidentiality is that plans change and transparency creates expectations that cannot always be met. Most organizations take a middle path: sharing that an individual is considered high-potential and discussing their development priorities without naming specific succession targets.
How do you handle succession planning for a founding CEO?
Founder CEO succession is among the most difficult and consequential transitions any organization faces. The founder’s identity, relationships, and knowledge are often deeply embedded in the organization’s operations and culture. Early and honest planning, external coaching for the founder on transition, board engagement in managing the process, and sometimes interim leadership arrangements are all elements of well-managed founder transitions. Avoiding the conversation does not reduce the risk; it concentrates it.
What is the role of the board in succession planning?
The board is responsible for CEO succession planning and for ensuring that management maintains appropriate succession depth for other critical roles. The governance committee or full board typically reviews succession plans annually, approves emergency succession protocols, and oversees the development process for the most senior succession candidates. Board-level succession oversight is a governance requirement, not an optional best practice.
How does succession planning link to competency frameworks?
Competency frameworks define the capabilities required in leadership roles at each level of the organization. Succession planning uses competency frameworks to assess candidate readiness and identify development gaps. Without a clear competency framework, succession assessment becomes subjective and inconsistent. Our guide on building a competency framework covers how to design the foundational tool that succession planning depends on.
