Transition Manager or Recruitment: the Real Cost Calculation.

A vacant industrial leadership position is expensive — but rarely in the way it’s calculated internally. Here is the full calculation, direct and indirect costs, based on a real case: a 300-person site, €45M in revenue. By Mounir Telkass, founder of MT-Transition.

Every month of vacancy has a price — one that’s rarely calculated in full

1. Direct costs — what you see right away

Overtime paid to N-1 managers “covering” the interim: €8,000 to €15,000 per month. Fees for an executive search firm to fill a permanent (CDI) position: €20,000 to €40,000 as a one-off. Onboarding and ramp-up of the new hire: 3 to 6 months before full effectiveness. These are the line items executive leadership looks at first — and they’re already not negligible.

2. Indirect costs — what really hurts

Every week without a pilot delays decisions: projects on hold, arbitrations postponed. Uncertainty over who’s in charge creates turnover among middle management. Without a clear course, performance indicators drift silently. And client or quality audits always land at the worst possible time — during the vacancy, never during the calm.

3. The full calculation on a real case

An industrial site of 300 people, €45M in revenue. Average time to fill a permanent leadership position: 5 months. Direct cost of the vacant position over that period: €85,000 to €120,000. Estimated performance loss over the same period — revenue, quality, client lead times: €200,000 to €400,000. Total cost of inaction: between €300,000 and €500,000. Cost of a transition director over those same 5 months: €60,000 to €90,000.

4. What the calculation still doesn’t say

A transition manager doesn’t replace the decision to hire permanently — they buy time to make that decision calmly, without the pressure of urgency. Many executive teams end up hiring the right permanent candidate with support from the transition manager who stabilized the site during the process. The two aren’t in competition; the second protects the first.

5. The real calculation isn’t cost against cost

Comparing a transition manager’s daily rate to a fully-loaded permanent salary means comparing two different things. The right calculation compares the cost of inaction — vacant position plus degraded performance — to the cost of continuity provided by transition management. In the vast majority of industrial cases I’ve seen, continuity costs two to four times less than inaction, and it also avoids client risk — the one risk that isn’t always recoverable.

The calculation changes depending on which role is vacant

A vacant position doesn’t cost the same depending on which leadership function is involved. An absent transition CFO means an immediate risk to bank reporting and covenants — banks don’t wait five months before asking for an updated financial position. An absent transition HR Director means a social climate that deteriorates silently, poorly negotiated settlement agreements, sometimes a works council that takes the initiative for lack of a counterpart. An absent transition CIO/CTO during an ERP migration means a project that keeps running on its own momentum without arbitration — and ends up costing far more to fix than to have steered properly. An absent transition site director means the entire operational decision chain seizes up: purchasing, quality, production — everything gets escalated to headquarters for lack of a local relay. The amount in euros therefore varies significantly by function, but the mechanism is constant: the more central the role is in the decision chain, the faster its absence translates into measurable cost elsewhere than on the payroll line.

Mistakes that distort the calculation, on the executive side

The first mistake is comparing only the visible budget lines — the transition manager’s daily rate on one side, the permanent employee’s fully-loaded salary on the other — without factoring in the cost of a failed hire. For an industrial leadership role, one in two permanent hires that fails within the first eighteen months costs, between severance, a new hiring process and repeated vacancy, the equivalent of a full year of fully-loaded salary. The second mistake is underestimating ramp-up time: a newly hired director takes on average three to six months to become fully operational on a site they’re discovering, a period during which the site keeps running in degraded mode. The third mistake, rarer but more costly, is hiring under pressure just to fill the gap — and finding yourself, eighteen months later, having to correct a bad decision all over again. A transition manager, by contrast, has a time-bound mandate from day one: the question of whether they’ll stay never arises, which removes a variable of uncertainty from the calculation rather than adding one.

Transition manager, interim management or consulting: don’t compare the wrong formulas

Part of the miscalculation comes from an initial confusion: comparing a consulting quote, an interim management daily rate and a transition management fee as if they were the same service. They aren’t. A consulting firm delivers a diagnosis and recommendations, without taking on operational responsibility for the role — see transition management vs consulting. Interim management provides caretaker continuity while a recruitment is underway, without a transformation mandate — see transition management vs interim management. Transition management, in the broader sense, covers both logics and more, with a measurable objective and full hierarchical responsibility. Comparing a consulting quote to the cost of a vacant position, for instance, systematically underestimates what it will actually cost to have someone execute the recommendations. The detail of the cost calculation itself — daily rate, fee, elements to factor in role by role — is developed on the dedicated page on the cost of a transition manager.

How to secure the handover to a permanent hire

The calculation doesn’t stop at the transition manager’s assignment: it includes how the aftermath is prepared. The executive teams that get the most out of the formula frame the question of “what’s next” from the first month of the assignment — parallel permanent recruitment, supported internal promotion, or a targeted extension if the context requires it. Since the transition manager isn’t meant to stay, they have no interest in delaying that clarification; on the contrary, they’re one of the best judges of the profile actually needed, having lived the role from the inside for several months. That’s a fundamental difference from a permanent hire made under pressure, where the job description is often written before the site’s real needs have even been identified. On the sites where I work, the most effective handover plays out over the last four to six weeks of the assignment: the transition manager contributes to the hiring brief, takes part in final interviews on the operational side if needed, and structures a documented handover — organization, ongoing files, points of attention — rather than a simple badge transfer. The cost of this handover is marginal compared to that of a new director left to fend for themselves with no handover at all, rediscovering the hard way arbitrations that were already settled six months earlier.

This calculation isn’t one-directional. For a stable position, in a context without particular urgency, with a pool of candidates already identified internally or through a trusted network, direct recruitment often remains the best option — simpler, less costly over time, and offering a long-term commitment that a transition assignment, by its very nature, cannot provide. Transition management makes full sense when at least one of these conditions is missing: urgency, uncertainty about the exact profile required, a crisis situation to stabilize before being able to calmly judge the right permanent candidate, or a role so specific that a failed hire would be particularly costly to fix. Doing this calculation honestly, role by role, avoids the two symmetrical pitfalls: rushing into a permanent hire that won’t last, or paying for a transition manager over a period the situation no longer justified.

Transition management isn’t a cost. It’s insurance against a higher cost — that of leaving the position empty while nothing gets done.

In practice, I advise executive teams to put this calculation in writing before even starting the search — on a single page, with three columns: cost of the vacant position per month, cost of transition management over the estimated duration, cost of a failed hire at this level of responsibility. This exercise, which rarely takes more than an hour, defuses most of the hesitation on principle and refocuses the decision on the numbers rather than an a priori preference for one status or the other.
