Our Take
Succession planning is not a senior leadership problem; it's an enterprise-wide vulnerability that most companies ignore until someone irreplaceable walks out the door.
Why it matters
A record 4.2 million Americans turned 65 in 2025 (per ScottMadden data), and AI is accelerating role changes at every level. If your bench doesn't exist now, you can't build it fast enough when a vacancy hits.
Do this week
HR: Audit roles that carry operational or strategic risk beyond the C-suite (payroll leads, benefits specialists, process experts) and group them by shared competencies, not titles, before the next retirement wave.
Succession planning is narrower and later than it should be
Only 21% of organizations have a formal succession plan in place (per SHRM). More than half have none at all. Of those that do plan, 72% concentrate succession planning exclusively at the executive and senior management level (per ScottMadden). The typical approach is reactive: a senior leader announces retirement, and HR starts the search from scratch.
That leaves the rest of the organization unaddressed. When a payroll manager with 15 years of institutional knowledge retires, or a mid-level operations lead gets poached, the disruption appears immediately but the vulnerability was invisible on the org chart. These gaps don't show up in quarterly reports. The operational cost does.
The timing pressure is real. A record 4.2 million Americans turned 65 in 2025, marking a sustained retirement surge (per ScottMadden). Simultaneously, AI is accelerating role changes at every level, shortening the window organizations once had to build bench strength.
Talent pools create flexibility and internal momentum
A talent pool is a defined group of potential successors for a category of similar roles. Rather than identifying a single backup for a single position, organizations group roles that share core competencies and build a pool of employees who could realistically move into any role within that group. The structure creates two downstream effects: expanded options when a vacancy occurs, and visible development paths that employees wouldn't otherwise see.
Employees who make internal moves, whether promotion or lateral shift, stay significantly longer than those who remain in the same role. According to LinkedIn's Future of Recruiting Report, employees stay 60% longer at companies with a strong commitment to internal hiring. External hires cost 18 to 20% more than internal promotions and tend to underperform for the first two years (per Wharton research).
Most critical: talent pools only work when workforce planning, performance management, and learning and development are connected. Most organizations run these as parallel tracks with no connection to succession. That disconnect is where the plan fails.
How to build and maintain a working talent pool
Start with risk, not rank. Identify roles that carry the most operational or strategic risk if unexpectedly vacated. A benefits specialist with deep carrier relationships represents as much transition risk as a director-level departure. Don't start with the C-suite.
Group by competency, not title. A compensation analyst and a benefits manager have different daily functions but both require regulatory fluency, analytical depth, and total-rewards knowledge. If meaningful development across roles isn't possible, they don't belong in the same pool. Keep the total number of pools manageable. Employees stretched across multiple pools end up with development plans that cover too many things to adequately prepare them for any one role.
Fill internally first. When building out each pool, start with internal candidates. Employees already familiar with the organization contribute faster than outside hires. External recruiting is the logical next step only if internal talent isn't available.
Tell employees they're in the pool. Gartner found that 86% of HR leaders believe career paths are unclear to many employees in their organizations. That ambiguity has a cost. Employees placed in talent pools need to know it, understand why they were selected, and agree to the development path. The conversation doesn't require elaborate framing, just clarity on why they were chosen and what readiness looks like.
Run a structured process when a role opens. Pull the pool, review candidates against the specific role requirements, meet individually to confirm interest, run a formal internal interview for all qualified candidates, and communicate the outcome to every candidate considered. That last step, notifying candidates who weren't selected, gets skipped often and erodes the trust that makes the pool worth maintaining.
Review annually. Every internal promotion creates another vacancy. Succession plans drift out of sync as people get promoted, change direction, or leave, and role requirements shift. A plan that hasn't been reviewed in 18 months may no longer reflect the organization it's supposed to support. Build in a formal review at least annually and update pools after any significant organizational change: restructuring, acquisition, meaningful shift in business direction.
