Most companies don’t fail at leadership transitions because they chose the wrong person. They fail because they defined the wrong job.
The volume of transitions is not the problem. The executive succession planning process most scaling companies default to is.
C-suite leadership transitions are happening right now at the highest rate in recent memory. CEO succession climbed to 12.5% in 2025, up from 9.8% the year before, according to research published by Harvard Business Review citing The Conference Board data. Nearly 60% of executives say they intend to change their role within the next three years. And research from Gartner and HBR puts the cost of a failed executive hire at 10 to 15 times the executive’s annual salary, once severance, lost productivity, and team disruption are factored in.
The instinct when a C-suite seat opens is to describe what the last person did and find someone who does it better. That is a reasonable starting point. It is a dangerous place to stop. The business you are building in the next three years is not the business you ran in the last three. The leadership profile that succeeded in the prior chapter may be exactly the wrong profile for what comes next. And yet the prior chapter is almost always the dominant input into how the role gets defined.
We have been running C-suite searches for companies scaling from $10M to $500M for two decades. The pattern is consistent: organizations that get leadership transitions right do one thing that others routinely skip. They define the transition before they design the search.That is the foundation of executive succession planning for scaling companies that actually works.
Replacement vs. Transition: The Distinction at the Heart of Executive Succession Planning for Scaling Companies
There is a meaningful and consequential difference between replacing a leader and executing a leadership transition.
Replacement asks: who can fill this seat?
Transition asks: what does this business need to be capable of that it is not capable of today, and what kind of leader enables that?
The outcomes of these two questions are not equivalent. A replacement hire stabilizes. A transition hire changes trajectory. At a genuine inflection point, whether that is a new market, a structural reorganization, a shift in competitive position, or an operating model that no longer fits the company’s scale, stabilization is rarely what the moment requires.
SHRM identifies mirroring the immediate predecessor as the most frequent error in succession. It feels safe. It almost never works. When organizations mirror the prior executive’s profile, they are essentially hiring for the last chapter. The next chapter has different requirements, different pressures, and often demands a fundamentally different kind of leadership capability.
The companies that navigate transitions well are specific. They know the business problem the new leader is being hired to solve, not just the function they are being hired to run. They know what the prior chapter ended and what the next chapter requires. They do that work before the search begins, and it changes everything about how the search is run.
Why the Wrong Process Persists (And What It Costs)
If defining the transition first is the right approach, why do so many organizations default to replacement?
Three reasons, in our experience.
The first is urgency. A C-suite seat going unfilled creates immediate pressure. The natural response is to launch a search quickly, which means pulling the last job description, updating it slightly, and starting to recruit. The diagnosis of what the role actually needs to become gets deferred to a conversation that happens later in the process, often too late to change the direction of the search.
The second is politics. Defining a role in genuinely forward-looking terms sometimes requires an honest conversation about whether the last executive’s tenure accomplished what the company needed, and whether the team that selected them is positioned to make a cleaner call this time. That conversation is uncomfortable, and organizations avoid it.
The third is that most hiring committees conflate defining the role with describing the candidate. A job scorecard that lists competencies, attributes, and experience requirements is not the same as a clear articulation of the business problem the new leader is being hired to solve. One describes a person. The other describes a need. The search should start with the need.
The cost of skipping that work is not abstract. HBR research puts the value destroyed by poor C-suite succession at close to $1 trillion a year among the S&P 1500 alone, driven primarily by underperformance when ill-suited leaders are placed into roles defined for a prior chapter of the business. A separate HBR study found that two out of five new CEOs fail within their first 18 months, not because they lacked talent, but because the succession process was broken before they arrived. Companies scrambling to replace a CEO without a clear forward-looking plan forfeit an average of $1.8 billion in shareholder value. That is not an HR problem. That is a governance failure.
What a Transition Brief Actually Contains
The defining work in executive succession planning for scaling companies happens before the search brief, not inside it. In our practice, this is where we add the most value before a search begins, and it is where organizations that try to run it themselves most commonly come up short.
A genuine transition brief answers four questions.
- What business problem is this leader being hired to solve? Not what function are they running. Not what the last person did. The specific strategic or operational challenge the organization cannot solve without new leadership capability in this seat.
- What does the prior chapter’s close look like, and what does the next chapter require? Every leadership tenure ends when the business it was designed for is no longer the business that exists. Being explicit about what changed, and what that change demands of the next leader, is the work that most search processes skip entirely.
- What does success look like at 90 days, one year, and three years? If the hiring team cannot articulate this before the search begins, they cannot hire for it. Executives hired into ambiguous roles fail at a dramatically higher rate than those hired into roles with clear, shared definitions of what winning looks like. As we have observed across searches at every growth stage from Series A through pre-IPO, executive succession planning for scaling companies looks different at each stage. The precision of the role definition is one of the strongest predictors of search success.
- What is this organization’s actual capacity to support a transition hire? A leader brought in to change trajectory needs something different from the organization than a leader brought in to run a stable function. Onboarding, access, political capital, and the willingness to tolerate the disruption that genuine transformation requires are all inputs to whether the right hire actually succeeds. Organizations that skip this question routinely hire the right executive and then fail to give them the conditions to do the job.
The Passive Talent Reality
The leaders best suited for genuine leadership transitions are almost never looking. They are running something, building something, or being quietly pursued by someone who found them before you did. Conventional hiring processes, posted roles, inbound pipelines, referral networks, are designed for candidates in motion. The executive who could change your trajectory is, by definition, not in motion.
Reaching that person requires a different starting point: a precisely defined opportunity, not a generic job specification. The quality of the transition brief is what makes the outreach compelling. Understanding which search model is designed for that kind of targeted pursuit matters more than most leadership teams realize until they are already mid-search and talking to the wrong pool of candidates.
The Hager View
We have seen this play out enough times that the pattern is clear. The organizations that get C-suite transitions right are not necessarily the ones with the biggest search budgets, the most sophisticated HR teams, or the most compelling stories to tell candidates. They are the ones willing to do the harder, slower work of defining the transition before designing the search.
That work is not comfortable. It requires honesty about what the prior chapter produced and what the next one demands. It sometimes surfaces disagreements within the leadership team about the direction of the business. It occasionally reveals that the answer is not an external hire at all.
But it is the work. And the organizations that skip it do not just hire the wrong person. They hire the right person for a job description that no longer matches the business, and they pay for it in time, momentum, and the window that closes while the wrong leader is in the seat.
That is what executive succession planning for scaling companies should look like when it is done right.Define the transition before you design the search. The rest follows from that.
