During a recent succession planning session, I asked the room a simple question: what are you actually trying to build, a replacement, or leadership capacity?
No one answered right away. Not because the question was hard, but because most organizations have never actually separated those two ideas.
The Trap
Most succession planning starts the moment someone is expected to leave or already has. A retirement is approaching, a key role feels vulnerable, a high-potential employee has been identified. The conversation almost always narrows to the same question: who could replace them.
That is a reasonable question to ask. It is also too small because it turns succession planning into an exercise in finding a person instead of building capacity. Readiness cannot be built quickly, and the business tends to change faster than people do. Waiting for the vacancy before you start developing someone means you are already behind.
Why It Breaks Down
When succession planning is built around one replacement, the organization becomes dependent on a single person, and development, if it happens, narrows to whoever is next in line. That single bet is more fragile than it looks. People leave, priorities shift, timelines change, and a lot can happen in the gap between naming someone and watching them actually step into the role.
It also affects everyone who was not chosen. Once a team knows who has been named the successor, the incentive to keep growing fades for everyone else, right when you need that broader group stretching the most.
There is a political cost too, one few leaders say out loud. When one person is visibly the anointed successor, development stops being about capability and starts being about favoritism. The organization may feel prepared, yet in reality business risk is high: development is concentrated in one person, and everything depends on nothing going wrong along the way.
The Shift
Strong organizations ask a different question. Instead of who is next, they ask what leadership capacity the business will actually need. That is a substantially different conversation. It moves the focus to future business requirements, emerging leadership signals, and where development can start now. It changes the goal from naming one successor to building capacity across multiple leaders.
Once we made the shift to leadership capacity, I asked a follow-up question: did they have a program or plan for actually developing that capacity? For every one of them, the answer was no. Nothing formal existed. Agreeing that capacity matters more than a name on a chart is the easy part. Building the way to develop it is the part most organizations skip.
Development Creates Signal
One idea generated more discussion in that session than anything else: development creates signal. Until someone is given room to actually lead, their potential is theoretical and readiness is an untested assumption. Leadership capacity only becomes visible once people are given broader responsibility, stretch opportunities, exposure to more complex situations, and visibility beyond their current role.
That is also why development has to be broad instead of narrow. You cannot verify potential in a single identified person sitting still. You have to give a wider group of people a real chance to step into bigger work, because that is the only way to find out who is actually capable, not just who appears capable.
Where to Start
You do not need to overhaul succession planning everywhere at once. Pick one role or one layer where the business is likely to need more depth soon, where you are already seeing leadership signals in people who are ready to grow, and start there.
What Leaders Often Miss
Most leaders think they are evaluating readiness. More often they are evaluating familiarity: who performs well today, who is reliable, who is comfortable in their current role. None of that tells you how someone will perform at the next level. That takes real experience, real observation, and deliberate development, not assumptions built on how someone shows up in the job they already have.
Leadership gaps rarely appear at a convenient time, and by the time an organization needs a ready leader, it is usually too late to start developing one. The organizations that get this right are rarely obsessed with naming a replacement. They are building depth, flexibility, and a bench of people who are ready with confidence, long before any specific vacancy exists.
What leadership capacity does your business need next, and how are you building it today?
