Most organizations say they do succession planning. Far fewer do it in a way that meaningfully prepares people for future roles. Too often, the practice amounts to a list of names scrawled on an org chart once a year, filed away, and never revisited. When a key leader leaves unexpectedly, the scramble begins anyway. The gap between intending to plan for succession and actually developing a pipeline of ready leaders is where learning and development professionals can make an enormous difference.
The first step is identifying which roles are truly critical. Not every position needs a formal succession plan. Critical roles are those where a vacancy would significantly disrupt operations, strategy, or revenue — and where the talent to fill them is scarce or takes a long time to develop. These are not always the most senior roles. A plant manager, a specialized technical lead, or a regional sales director can be just as critical as a vice president if losing that person would stall key outcomes. L&D leaders should work with business partners to map these roles, looking at factors like the uniqueness of the knowledge held, the complexity of the function, and how long it takes to bring someone to full competence. This exercise alone often reveals blind spots leadership has never discussed openly.
Once critical roles are identified, the next task is assessing readiness. This means looking at potential successors honestly — not just at who has been around the longest or who the current incumbent recommends. Readiness assessment should consider both performance and potential, which are not the same thing. A high performer in their current role may lack the strategic thinking, stakeholder management, or cross-functional experience needed one level up. Conversely, someone who has been quietly building those capabilities may be overlooked because they are not yet in a visible position. Structured assessment — using tools like behavioral interviews, leadership simulations, multi-rater feedback, and development conversations — gives a clearer picture than gut instinct.
Here is where succession planning and learning and development become inseparable. Identifying a successor is only useful if you actively build their readiness over time. This means creating individualized development plans that close specific gaps. If a successor needs more financial acumen, pair them with the CFO for a stretch project. If they need experience leading through ambiguity, give them ownership of a cross-functional initiative. Formal learning programs can play a role — leadership development cohorts, executive education, coaching engagements — but the most powerful development happens through experience. Job rotations, acting assignments when leaders are on leave, and deliberate exposure to board-level or customer-facing situations accelerate readiness in ways that classroom training alone cannot.
Several common pitfalls undermine even well-intentioned succession efforts. The first is treating it as a one-time event instead of a continuous process. Organizations that review their succession plans only during annual talent reviews tend to find those plans outdated by the time they are needed. Business priorities shift, people leave, and development gaps change. Succession planning should be a living conversation, revisited quarterly or whenever there is a significant organizational change.
Another pitfall is lack of transparency. Some organizations keep succession plans entirely secret, believing that telling someone they are being developed for a future role creates entitlement or that telling someone they are not on the list will demoralize them. In practice, secrecy often backfires. High-potential employees who are not given a clear growth path are more likely to leave, and those who are being developed benefit enormously from knowing the direction and purpose of their development activities. Full transparency about specific timing or guaranteed promotions is not necessary, but open conversations about career aspirations, development areas, and organizational needs build trust and engagement.
A third common mistake is over-relying on a single successor for each role. If that person leaves, you are back to square one. Building a broader bench — even if not every candidate is immediately ready — creates resilience. It also promotes a culture of development rather than a culture of waiting for one person to be anointed.
Finally, organizations sometimes confuse replacement planning with succession planning. Replacement planning answers the question, 'Who would step in tomorrow if this person left?' That is useful for emergency continuity, but it is reactive. True succession planning is proactive and developmental: it asks, 'Who could be ready in one to three years, and what do we need to do now to prepare them?'
For L&D professionals, succession planning offers a powerful strategic lever. It provides a clear, business-driven rationale for development investments. It connects individual learning journeys to organizational needs. And it positions the L&D function not as a provider of courses but as a partner in building the leadership capacity the organization will need to thrive. When you tie your development programs, coaching initiatives, and experiential learning opportunities directly to succession needs, you move from order-taking to strategic influence — and you make the organization more resilient in the process.
