Succession Planning Best Practices 2025

Summary: Eight practical succession planning best practices for 2025 to build a resilient leadership pipeline, ensure continuity, and develop ready-now leaders.

Introduction

Picture this: a key leader unexpectedly steps down. Panic sets in. Operations stall, and institutional knowledge walks out the door. Do you have a plan, or just a problem? Effective succession planning isn’t a “nice-to-have” for some distant future; it’s a critical survival strategy today. It’s the bedrock of organizational resilience, helping companies thrive through expected and unexpected transitions.¹

This guide skips the theory and focuses on eight actionable best practices that separate organizations that prepare from those that panic. You’ll find practical steps, implementation tips, and real-world examples to help you build a leadership pipeline that’s fit for 2025 and beyond.

In the sections that follow, you will learn how to:

• Identify and develop a deep bench of high-potential employees.
• Create individualized development plans aligned with strategic goals.
• Implement job rotations and stretch assignments to build versatile leaders.
• Establish transparent processes to manage transitions smoothly.

Let’s build a future-proof foundation for your team, starting today.

1. Start Succession Planning Early and Make It Continuous

Shift succession planning from a reactive scramble to a proactive, continuous function. Succession planning doesn’t begin when a retirement announcement is made; it starts years in advance and becomes part of regular strategic planning. Treat talent development and leadership transition as an ongoing cycle integrated into core operations.

Treating succession planning as a living process lets you identify and develop high-potential employees over time so they have the skills, experience, and institutional knowledge when a key role opens. This long-term view minimizes disruption, maintains operational stability, and fosters a culture where internal growth is prioritized.

Why this matters

A reactive approach often leads to hasty decisions, costly external hires, or internal conflict. By making succession planning continuous—typically starting 3 to 5 years before an anticipated transition—you align talent strategy with long-term business goals and build a pipeline of ready-now leaders.

Key insight: The goal is not a static list of names but a dynamic talent pool that changes as business strategy and individuals’ aspirations evolve.

Real-world examples

• Procter & Gamble is well known for a promote-from-within culture that builds leaders over many years.²
• IBM identified future CEO candidates long before appointments, giving them diverse experience across the business.³

Implementation tips

• Integrate succession reviews into annual strategic planning.
• Identify high-potential employees at all levels, not just the C-suite.
• Use living documents for succession plans and update them regularly.
• Communicate the process clearly to reduce anxiety about career progression.

2. Identify and Develop a Deep Bench of High-Potential Employees

Move beyond naming a single heir and build a deep bench of qualified candidates for each critical role. Use performance data, competency frameworks, and potential assessments to spot future leaders early, then give them targeted development, rotations, and mentorship. Aim for a 2–3 deep talent pool per critical role.

A deep bench creates options and resilience. The focus shifts from replacement planning to talent pool development, ensuring the organization isn’t dependent on one person.

Why this matters

Relying on a single successor is risky. That person could leave or fail to adapt. Multiple candidates create healthy options and internal motivation.

Real-world examples

• PepsiCo and Microsoft emphasize deep bench strength and rotation programs as central to leadership continuity.⁴

Implementation tips

• Use a 9-box grid to assess current performance and future potential.
• Identify 2–3 candidates per role to avoid single-point dependency.
• Be transparent about development programs but confidential about specific succession lists.
• Reassess potential regularly; status can change.

3. Create Individual Development Plans (IDPs) Aligned with Succession Goals

An IDP is a customized roadmap that connects a potential successor’s current skills to the requirements of a future role. IDPs should be collaborative documents co-created by the employee, manager, and HR, and they should include specific competencies, experiences, and milestones.

Why this matters

Without IDPs, identifying talent is only an exercise in list-making. IDPs turn identification into measurable development.

Key insight: Personalized development beats one-size-fits-all training. Include stretch assignments, mentoring, and cross-functional exposure.

Real-world examples

• Johnson & Johnson and Marriott use personalized development plans tied to specific competency targets to build reliable pipelines.⁵

Implementation tips

• Adopt the 70-20-10 model: 70% on-the-job experience, 20% coaching, 10% formal training.
• Collaborate on IDPs with the employee, manager, and HR partner.
• Set short-term (6–12 months) and long-term (2–5 years) goals with quarterly check-ins.
• Prioritize cross-functional projects in IDPs. Consider linking to an IDP template or tool for managers to use, such as IDP templates.

4. Implement Cross-Functional Job Rotations and Stretch Assignments

Rotate future leaders across functions, regions, and business units. Job rotations and stretch assignments broaden experience, build networks, and test adaptability. These assignments accelerate learning and develop an enterprise-wide perspective required for senior roles.

Why this matters

Leaders confined to a single functional silo often lack the cross-enterprise view needed for complex decision making. Rotations and stretch assignments build that perspective.

Key insight: The aim is to cultivate a strategic mindset by exposing leaders to multiple parts of the business.

Real-world examples

• GE’s rotational programs have long been credited with producing well-rounded executives.⁶
• Shell and Amazon use international and high-impact assignments to prepare leaders for complexity and scale.⁶

Implementation tips

• Plan rotations 12–18 months in advance and run assignments long enough (18–24 months) for meaningful results.
• Select stretch assignments that challenge but don’t set candidates up for failure.
• Provide onboarding and mentorship for each new role.
• Debrief after assignments to capture lessons learned and measure outcomes.

5. Establish Transparent Communication and Governance Processes

Create a governance framework that explains the succession process while keeping individual names confidential. A talent review board or succession committee with clear roles reduces speculation and builds trust.

Why this matters

Opaque processes breed cynicism and talent loss. Transparency about the how, not the who, demonstrates fairness and encourages employees to engage with development opportunities.

Key insight: Communicate criteria, timelines, and available development programs, but keep specific successor lists confidential.

Real-world examples

• Companies such as Costco and Accenture use competency frameworks and clear promotion criteria to reduce ambiguity in advancement.⁷

Implementation tips

• Create a succession planning charter documenting governance, roles, and timelines.
• Train managers to have developmental conversations without making concrete promises.
• Hold regular talent reviews (quarterly or semi-annual) to assess pipeline health.

6. Integrate Succession Planning with Overall Talent Management Strategy

Succession planning should be woven into recruitment, performance management, learning and development, and retention. When integrated, every talent decision is filtered through the lens of future leadership needs.

Why this matters

A siloed approach wastes resources. Integration ensures hiring, development, and promotion all support the same leadership requirements.

Key insight: Succession planning should inform recruitment and be informed by performance and development systems.

Real-world examples

• GE’s Session C talent reviews historically combined performance, potential, and succession into one strategic process.⁶

Implementation tips

• Map talent processes to identify where succession data should flow.
• Use a unified competency model across hiring, development, and promotion.
• Leverage HR technology to connect data and produce actionable insights. See our talent strategy resources at Talent Strategy.

7. Include Emergency and Interim Succession Plans

Prepare for sudden, unexpected departures by identifying interim successors and documenting emergency procedures. Interim leaders stabilize operations and buy time for a careful permanent search.

Why this matters

Sudden leadership gaps can cause chaos and erode stakeholder confidence. An interim plan ensures continuity and protects organizational momentum.

Key insight: Interim successors are stewards whose priority is stability and continuity, not transformation.

Real-world examples

• Apple’s activation of an interim plan when its CEO took medical leave provided market reassurance and operational steadiness.⁸

Implementation tips

• Identify interim successors for critical roles who can maintain operations immediately.
• Create emergency playbooks that document responsibilities, contacts, and system access.
• Prepare templated communications for internal and external stakeholders.
• Run annual tabletop exercises to test readiness and brief the board on protocols.

8. Measure, Monitor, and Continuously Improve Succession Planning Effectiveness

Measure program effectiveness with clear KPIs, monitor progress, and iterate. Use leading indicators (pipeline strength, successor readiness) and lagging indicators (internal fill rate, new leader performance) to assess impact.

Why this matters

Without measurement, succession planning can become a check-the-box activity. Data-driven evaluation lets you identify gaps, validate investments, and demonstrate ROI to leadership and the board.

Key insight: What gets measured gets managed. Use analytics to reveal hidden risks and guide strategic adjustments.

Real-world examples

• Firms such as IBM and P&G report successor readiness and internal promotion metrics to the board to ensure visibility and accountability.⁹

Implementation tips

• Start with 5–10 core metrics and expand as your program matures.
• Conduct post-transition reviews at 90 days, 6 months, and 1 year to capture lessons and adjust onboarding.
• Track diversity in succession pools to identify biases and build an inclusive leadership team.
• Report metrics to the board quarterly to drive decisions about talent investment.

A data point to note: many organizations cite leadership continuity as a top business risk; integrating succession metrics into board reporting increases visibility and ties talent to performance outcomes.¹⁰
