Talent Management & Succession Planning: The Strategic Link Most Organisations Miss

Why this research matters

Why succession planning remains one of HR's most neglected disciplines - and a practical framework for building an evergreen talent pipeline.

The Succession Planning Crisis

The statistics are striking in their consistency. SHRM's most recent succession planning research (2025) reveals that only 22% of HR leaders report having a formal succession plan in place. A further 24% have informal, undocumented plans. The remaining 56% have no succession plan at all . This is not a finding about small, resource-constrained organisations - the majority of companies without formal succession plans are mid-sized enterprises where the sudden departure of a key leader would create measurable disruption to operations, client relationships, and financial performance.

The practical consequences of this gap are well-documented. BCG research (2024) notes that average CEO tenure has declined to approximately 6.8 years - meaning the average large company will face a CEO succession event roughly every seven years. For many, that event will be unplanned, and the cost - in external search fees, transition performance dips, and cultural disruption - will be significant. BCG recommends treating succession planning as an "evergreen system" rather than an event triggered by a departure or a retirement announcement.

The Talent Management–Succession Link

Succession planning that is disconnected from talent management is a list-making exercise, not a pipeline-building process. The distinction matters: a succession list names who might step into a role. A succession pipeline identifies, develops, and prepares people who are systematically growing toward readiness for critical roles. The pipeline requires active investment - stretch assignments, mentoring, executive exposure, formal development programmes - not passive identification.

The most effective talent management systems connect five processes into a single, coherent cycle: identification (who has high potential?); assessment (what are their current strengths and development areas?); development (what experiences and programmes will accelerate their growth?); deployment (what roles and assignments will stretch their capability?); and retention (what are we doing to keep them engaged and committed?). Succession planning lives at the intersection of all five.

Defining "High Potential" Rigorously

Most organisations define high potential informally - as the person who is performing well and has impressed their line manager. This definition conflates current performance with future potential and produces a talent pool that is systematically biased toward the visible, the confident, and those with strong relationships with influential leaders. Research consistently shows that the most effective high-potential identification frameworks use explicit criteria - typically: learning agility (the capacity to learn from experience and adapt), cognitive ability (the capacity to handle increasing complexity), and leadership motivation (the genuine desire to take on broader responsibility).

SHRM (2025) reports that 42% of talent management executives have identified creating a formal succession strategy as a top focus for 2026, and 47% of CHROs cite succession management as their top priority for leadership continuity. The organisations that move first to build rigorous, evidenced talent pipelines will have a significant competitive advantage in leadership depth as talent markets remain tight.

The 9-Box Grid: Use It Carefully

The 9-box grid - mapping performance against potential on a 3×3 matrix - is the most widely used talent management tool in large organisations. Used well, it creates a shared language for talent conversations and forces explicit discussion of both dimensions. Used poorly, it produces categorical labels ("solid performers," "rising stars") that create self-fulfilling prophecies. The evidence on 9-box limitations is clear: potential ratings are highly susceptible to manager bias , tend to correlate more strongly with personality and social visibility than with actual future performance, and once assigned, are difficult to change even when an individual's trajectory changes significantly. Use the 9-box as a starting point for conversation, not as a definitive classification system.
