What Is Succession Planning?
Succession planning is a systematic process of identifying and developing employees who have the potential to fill key leadership and critical positions within an organization. It ensures business continuity by preparing internal candidates for important roles before vacancies occur, whether through retirement, promotion, departure, or unexpected events.
Effective succession planning is not just about replacing the CEO. It extends to all positions that are critical for organizational operations, including senior leaders, technical specialists, and key contributors whose departure would significantly impact the business. For SHRM exam candidates, succession planning is an important topic within the People domain and connects to broader organizational strategy.
Step 1: Identify Critical Positions
The first step in succession planning is determining which positions are critical to organizational success. Not every role requires a formal succession plan. Focus your efforts on positions that meet one or more of these criteria:
- Strategic impact: Roles that directly influence organizational direction and performance
- Specialized knowledge: Positions requiring rare or difficult-to-replace expertise
- Single points of failure: Roles where only one person holds critical institutional knowledge
- Leadership positions: Senior roles that set direction for teams, departments, or the entire organization
- Revenue-critical roles: Positions directly tied to revenue generation or key client relationships
Work with senior leadership to identify and prioritize these positions. Create a risk assessment that considers the likelihood of vacancy (upcoming retirements, for example) and the impact a vacancy would have on operations.
Step 2: Define Success Profiles
For each critical position, develop a success profile that describes what the ideal successor looks like. A success profile includes:
- Essential competencies and skills required for the role
- Experience and knowledge requirements
- Leadership qualities and behavioral expectations
- Business acumen and strategic thinking capabilities
- Cultural fit and values alignment
The success profile becomes the standard against which you evaluate potential successors. It should reflect what the role will require in the future, not just what it demands today. Consider how the position might evolve as the organization's strategy and environment change.
Step 3: Assess and Identify Potential Successors
With critical positions and success profiles defined, the next step is identifying internal candidates who have the potential to fill these roles. Assessment methods include:
Performance and Potential Reviews
Use a combination of performance data and potential assessments to evaluate candidates. Performance tells you how well someone is doing in their current role; potential tells you how well they might perform in a future, more demanding role. Common frameworks include the 9-box grid, which plots performance against potential to categorize employees into development groups.
Assessment Tools
Supplement managerial assessments with objective tools such as 360-degree feedback, leadership assessments, cognitive ability evaluations, and personality inventories. These provide data-driven insights that complement subjective manager observations.
Talent Review Meetings
Bring senior leaders together for structured talent review discussions. These meetings allow leadership to share perspectives on high-potential employees, calibrate assessments across departments, and build organizational awareness of the talent pipeline. The conversation itself is as valuable as the outcomes, because it builds leadership commitment to talent development.
Step 4: Develop Successors
Identifying potential successors is only the beginning. The real work lies in developing their capabilities to close the gap between where they are now and where they need to be. Development strategies include:
- Individual development plans (IDPs): Create personalized plans that target specific competency gaps for each successor candidate.
- Stretch assignments: Assign projects that push candidates beyond their current skill level and expose them to new challenges.
- Job rotations: Move candidates through different functional areas to broaden their perspective and build cross-functional knowledge.
- Mentoring and coaching: Pair successors with experienced leaders who can share insights, provide guidance, and model effective leadership.
- Executive education: Invest in formal learning programs such as leadership courses, MBA programs, or industry-specific training.
- Shadowing and exposure: Give candidates opportunities to observe senior leadership decision-making, attend board meetings, or participate in strategic planning sessions.
Step 5: Monitor, Evaluate, and Adjust
Succession planning is not a one-time exercise. It requires ongoing monitoring and adjustment:
- Review succession plans at least annually and update them when organizational needs, personnel, or strategy changes.
- Track the development progress of successor candidates against their IDPs.
- Measure the effectiveness of your succession planning program through metrics like internal fill rate, time to fill leadership positions, and successor readiness levels.
- Adjust your approach based on lessons learned from actual successions. Did the prepared successor succeed? What could the development process have done better?
Use HR metrics to demonstrate the value of succession planning to senior leadership. Data showing that internal promotions are faster, less expensive, and more successful than external hires builds ongoing support for the program.
Common Succession Planning Pitfalls
- Focusing only on top leadership: Extend planning to all critical roles, not just C-suite positions.
- Keeping plans secret: While not every detail needs to be shared, employees identified as high-potential should know they are being developed for advancement.
- Lack of diversity: Ensure your successor pool reflects the diversity of your workforce and customer base. Homogeneous leadership pipelines perpetuate blind spots.
- Set-it-and-forget-it mentality: Plans become outdated quickly. Regular reviews and updates are essential.
