The Sector Fit Trap: What Most Interim Briefs Get Wrong

by Nicolas Henckes, Founder & CEO

Almost every interim mission we take on starts with a brief, and almost every brief contains some version of the same line: looking for someone with direct experience in our industry. It sounds like due diligence. In practice, it is usually the single line in the document that costs the client the most, and buys them the least.

We understand where the instinct comes from. If you run a logistics company, or a private bank, or a manufacturing plant, it feels obvious that the person stepping into the CEO chair, even temporarily, should already know how the trucks move, how the compliance desk works, how the shop floor operates. Familiarity feels like safety. But familiarity and the actual skill being hired for are two different things, and the brief usually confuses them.

What the requirement actually costs

A sector-experience requirement narrows the candidate pool before anyone has even asked what the mission requires. In a market the size of Luxembourg, that pool was already small. Add "must have led a company in our exact sub-sector" and it can shrink to a handful of people, several of whom are not available on short notice, some of whom have never actually led a transition of the kind the client is facing.

The search then takes longer, precisely at the moment the client can least afford delay: a founder stepping back, a restructuring already underway, a gap left by a sudden departure. Every week spent widening the sector search past the initial shortlist is a week the underlying problem does not wait for.

There is also a subtler cost. A narrow sector filter creates a false sense of security. The board feels reassured because the candidate "speaks the language of the industry," and stops asking the harder question: has this person actually done the thing we need done, in a company that looked like ours, under pressure of the kind we are under.

The skill being hired is rarely the sector

Most of what an interim executive is brought in to do is not, in fact, industry-specific. Reading a P&L under stress, rebuilding trust with a team that did not choose them, making the first hard call within the first two weeks, running a structured process during a founder succession, stabilising suppliers and clients after a sudden departure: these are transferable skills, built by doing them, not by spending twenty years in one industry.

We have seen this work in both directions. An interim CFO who spent a career in retail can stabilise the finance function of a family-owned industrial business within weeks, because the actual problem, an unreliable cash forecast and a finance team that never had real oversight, is the same problem wearing a different uniform. We have also seen the opposite: a candidate with fifteen years in exactly the right sector, who had never actually led a transition, freeze in the first month because the job they were hired for, stabilise and rebuild, was simply not a job they had done before, industry knowledge notwithstanding.

Sector knowledge matters where the domain itself carries the risk: a regulated manufacturing process, a licensed activity, a technical safety requirement that cannot be learned on the job in three weeks. Financial services and insurance are the clearest examples. In Luxembourg, an effective manager of a bank, an investment firm, or a management company does not simply start the job once the board decides. The appointment goes through a fit and proper review by the CSSF, built around prior senior-level experience in similar activities, and the timeline for that approval sits outside anyone's control, including the client's and ours. Insurance and reinsurance undertakings face the equivalent constraint under the CAA, which requires every company to be led by a dirigeant agréé approved on grounds of qualification and good standing. That is not a preference for sector fluency, it is a structural precondition, and it changes what "available to start" actually means. Healthcare carries a related but different constraint, usually tied to professional qualifications required to hold certain titles or sign off on certain acts, rather than a prior approval of the executive as such. Those cases are real, but they are narrower than most briefs assume, and worth naming explicitly rather than defaulting to as a blanket requirement.

What actually predicts whether the mission succeeds

If sector experience is not the reliable signal, something else has to be. In practice, the more useful question is not "has this person worked in our industry" but "has this person handled our type of situation." A founder succession, a post-acquisition integration, a turnaround under cash pressure, a digital transformation running in parallel with day-to-day operations: each of these is a distinct skill set, built through repetition, and it travels across industries far more easily than it travels across situation types.

A brief built around situation type, rather than sector label, tends to surface a wider and often stronger pool of candidates, available sooner, with a track record that actually matches what the mission will demand in its first difficult weeks.

Rewriting the brief

None of this means industry context is irrelevant. Outside the small set of sectors where regulatory approval or professional qualification is a precondition of the role itself, it belongs lower in the brief, and phrased differently: not "must have led a company in this sector," but "must be able to get up to speed on this sector's specifics within the first month," a much lower and much more honest bar. The requirement that should sit at the top of the brief is the one that actually predicts performance: what kind of situation is this, and who has proven, under similar conditions, that they know how to handle it. Where regulatory approval genuinely gates the appointment, that becomes a separate, earlier question, answered before the search even starts, not folded into the same line as sector familiarity.

The next time a brief crosses your desk with "sector experience required" as its first line, the question worth asking is not whether the candidate in front of you has it. It is whether that line is describing the actual risk in this mission, or simply the risk that felt easiest to write down.
