Capability versus match
(the two questions every senior hire needs to answer)

Every consequential senior appointment has to answer two different questions, and most selection processes only answer one of them. The first is capability: can this person do the job? Interviews, references, track record and psychometrics were built to answer it, and by the final stage of a well-run search they usually have. The second is match: will this person work here, with this CEO, in this leadership team, against what this plan will demand over the next two years, when the pressure is on? None of the tools that answered the first question were designed to answer the second, and it is the second on which most senior hires actually turn.

The distinction matters because the two questions behave differently. Capability travels with the person. A chief financial officer who has run a refinancing, integrated three acquisitions and taken a business through exit carries those capabilities into whichever company hires them next. Match does not travel. It is a property of a specific pairing in a specific environment at a specific point in a plan, which is why the same executive can be excellent in one PE-backed business and gone from the next inside a year, with nothing about their competence having changed in between.

The failure rate at senior level has been stable for a long time, and it is not a capability problem. Heidrick & Struggles reported nearly two decades ago that 40 per cent of senior executives hired were pushed out, had failed or had quit within eighteen months, and the figure has been reproduced in one form or another in most studies since. In private equity the pattern is sharper. AlixPartners' 2026 leadership survey found that nearly two thirds of PE firms replace a portfolio company chief executive during the holding period, that 83 per cent of PE executives say unplanned CEO turnover lengthens the hold, and that roughly half say it reduces returns. Those are not the numbers of an industry that is bad at assessing whether people can do the job. They are the numbers of an industry that assesses capability well and match hardly at all.

When a senior hire fails, the post-mortem rarely says the person could not do the work. It says the working relationship with the chief executive broke, or the executive never landed with the team, or the plan asked for something the person's operating pattern could not give. It usually says all three happened in the same quarter, the one that put everybody under pressure at once. Those are all match failures. They are also all foreseeable, because the ingredients were present before the offer was signed: the CEO's pattern under pressure, the team's state, the plan's demands and the candidate's own pattern were all in existence and all observable. The process simply was not looking at the interaction between them.

Part of the reason the second question goes unasked is that the industry has become very good at the first. There is now serious, large-sample evidence on the attributes that distinguish executives who succeed in PE-backed companies. ghSMART's analysis in Harvard Business Review this summer, for instance, identifies a practical commercial orientation, the ability to set strategy under pressure, wide influence, a willingness to take risk on talent, and broad interpersonal range as the capabilities that separate chief executives who make the leap from corporate life to PE ownership. Work like that is valuable, and a hiring process that ignores it is careless. It answers the capability question at a higher standard than the industry used to manage. It does not, and does not claim to, answer whether this particular executive with those attributes will work with this particular CEO, whose own pattern under pressure is already fixed, in a team whose habits are already formed, against a plan whose timetable was set before the search began.

So what does the match question actually consist of? In our work it resolves into four interactions, with the requirements of the role running through all of them. The first is the candidate and the CEO: where the two patterns under pressure compound and where they collide, who withdraws and who escalates when the first miss lands, what the CEO does when a direct report disagrees and what the candidate does when overruled. The second is the candidate and the team: what this executive needs from an environment in order to perform and whether this team, in its current state, provides it. The third is the candidate and the plan: which of the conditions the next twelve to twenty-four months will create, in pace, ambiguity, cost pressure, integration or fundraising, will activate the candidate's strengths and which will expose the vulnerabilities. The fourth is the candidate and the role itself: the specific pressures this seat creates, measured against a scorecard agreed before assessment begins.

The reason interviews cannot see any of this is structural rather than a failing of interviewers. An interview shows a candidate at their prepared and composed best, in calm conditions, talking about themselves. The decision being made is about a different person: the one who turns up in the worst fortnight of next year, when preparation has run out. Across more than a hundred PE-backed leadership teams, our Pressure Profile work has produced the same picture repeatedly. Under real pressure every leader moves in a characteristic way. Some absorb work and go quiet, some accelerate and open more threads than they close, some swing between the two, some stop. Roughly a quarter of the leaders in our dataset are operating in a threat state under pressure, which changes how they decide, communicate and relate. None of that is visible in an interview, because none of it appears until the pressure does.

Answering the second question therefore requires evidence of a different kind. On the candidate's side it means evidence of pattern rather than self-description: a survey built to resist rehearsed answers, a biographical interview that walks through dateable, verifiable pressure episodes across the career, and structured interviews with referees who have watched the candidate under real load, all against the same framework so that the findings can be counted rather than felt. On the environment's side it means an honest read of the CEO's own pattern, of the team's current state, and of what the plan will actually ask for and when. On the decision side it means a scorecard agreed before assessment begins and a verdict on the match rather than a score for the person: go, conditional go, or no-go under the current conditions, with the conditions named specifically enough to act on and the reasoning shown.

It also requires a discipline the assessment industry has largely avoided, which is going back to check. Any verdict on a match is a prediction about how a particular pairing will behave under conditions that have not yet arrived. The only honest thing to do with a prediction is to test it, six months in, against what the new executive's colleagues actually observe, and to show the client the result whichever way it falls. Private equity already applies this logic to every investment it makes. It is striking how rarely the same rigour reaches the appointment that decides whether the value-creation plan has an owner.

None of this diminishes the first question. A candidate who cannot do the job should never reach the point where the second question is worth asking, and a process that skips capability in favour of chemistry is worse than one that skips chemistry in favour of capability. The point is sequence. By the time a search has produced a preferred candidate, the first question has been answered at considerable expense. The second question, the one that will actually decide the outcome, is the cheaper of the two to answer and by far the more expensive to ignore. The right moment to ask it is the one most boards currently skip: after the process has said yes, and before anyone has signed.
