What Succession Planning Looks Like When It Actually Works

The Aspirations That Don’t Survive Contact with Reality

“We’ll identify high potentials objectively.” In practice, the list is a proximity list. It skews toward people the executives have seen present, people at headquarters, people in the functions the CEO came up through. That’s not corruption; it’s how human attention works. But if you don’t name it, you’ll defend a biased list as if it were a measurement.

“Ready now / ready in 1–2 years / ready in 3–5 years.” The most fictional column in corporate life is “ready in 3–5 years.” Nobody knows what that role requires in three to five years. Half the time, nobody knows if the role will exist. That column is a way of feeling covered without doing anything, and it quietly converts urgency into patience.

“We keep the list confidential to avoid setting expectations.” So the high potential doesn’t know she’s a high potential. She gets a recruiter call in a soft market and reasonably concludes nobody here has plans for her. You protected yourself from an awkward conversation and paid for it with the person.

“The successor will want the role.” Increasingly, no. There’s a real and growing pattern of strong individual contributors looking hard at what the manager job has become — the span, the squeeze, the sandwiching — and declining. Your plan assumes ambition flows upward automatically. Check that assumption with actual humans before you build on it.

“We’ll revisit it annually.” The plan is built in Q3, presented to the board in Q4, and by March there’s been a reorg, two departures, and a new operating model. An annual cadence means your plan is stale most of the year.

“The 9-box will tell us.” The 9-box is a conversation-starter that got promoted to oracle. It’s a snapshot of two subjective judgments rendered as a coordinate. It’s fine as a way to force a discussion. It’s terrible as a source of truth.

What Working Succession Planning Actually Looks Like

Start with roles, not people. The first question isn’t “who are our high potentials?” It’s “which twelve roles would genuinely hurt us if they emptied out in the next eighteen months, and why?” Sometimes it’s a title. Often it’s an unglamorous role held by someone with twenty years of relationships and undocumented judgment. Rank by damage-if-vacant, not by org-chart altitude.

Define readiness as evidence, not opinion. “Ready” should mean something you could point at. She has run a P&L through a downturn. He has managed a team through an integration. She has delivered bad news to a customer and kept the account. If you can’t name the evidence, you don’t have a readiness rating — you have a hunch with a color code.

Build readiness through assignments, not nominations. Nobody has ever become ready by being on a list. They become ready by being handed something hard, slightly early, with support and a real chance of visible failure. The best succession systems I’ve seen are, functionally, assignment-allocation systems. The grid is downstream.

Tell people something true. You don’t have to promise a role. You can say: “You’re someone we’re investing in. Here’s the experience we think you’re missing. Here’s what we’re going to do about it in the next twelve months.” That’s honest, it’s actionable, and it doesn’t commit you to a promotion that may not exist. Silence isn’t neutral. Silence reads as absence of interest.

Assume attrition on your own list. Plan for a meaningful share of your named successors to be gone, promoted elsewhere, or no longer interested by the time you need them. Depth of two isn’t depth. And this is why the “we’ll keep it quiet” instinct is so expensive — the people best positioned to leave are exactly the people you named.

Pressure-test it out loud, at least quarterly. Put a role on the table. Ask: this person leaves Friday — what actually happens Monday? Watch the room. The pauses tell you more than the spreadsheet does. Fifteen minutes, one role, every leadership meeting. Do that for a year and you’ll have stress-tested most of the org.

Cover the transition, not just the name. Half of succession failures aren’t selection failures — they’re onboarding failures. The right person, dropped into the role with no relationship map, no context on the standing conflicts, and a predecessor already gone. Name the successor and design the first ninety days.

The Bottom Line

Succession planning fails when it’s treated as a document, and works when it’s treated as a series of decisions about who gets which hard assignment this year.

The organizations that get it right are rarely the ones with the most elegant frameworks. They’re the ones where a small group of leaders sits down regularly, argues honestly about who’s actually ready, and then does something concrete about the gap before the next review cycle.

Everything else is a very tidy spreadsheet describing a bench you don’t have.
