Transition management: getting an operational executive on site, fast.

Where transition management comes from, and why the term is sometimes confusing

Transition management (“interim management” in Anglo-Saxon countries) initially developed in the Netherlands during the 1970s, before spreading to the UK and then to France from the 1990s onward. The term is often confusing in France for two reasons. First, it should not be confused with traditional temporary staffing (temp work regulated by a staffing agency under French labor law): a transition manager is not a temp worker in the legal sense, they generally work under a service agreement through their own structure or an umbrella company (portage salarial). Second, “transition” does not necessarily mean a long-term strategic transformation: the vast majority of industrial transition management assignments aim to stabilize a specific operational situation (vacant position, crisis, ramp-up) over a period of a few weeks to a year, not to run a multi-year transformation plan.

Employed, self-employed, or umbrella company: does status change anything?

In practice, on the ground, a transition manager always works under one of three distinct legal statuses, without this changing the nature of the assignment for the client company. As a self-employed professional, through their own structure (sole proprietorship, single-shareholder company), they invoice the firm or client directly, with full contractual autonomy. Under an umbrella company (portage salarial), an umbrella firm issues payslips and handles administrative and social matters, which reassures some managers about the continuity of their social rights. More rarely, a transition manager may be directly employed by a firm such as MT-Transition for certain specific assignments. For the client company, this choice of status remains largely transparent: what matters contractually is the service agreement signed between the company and the firm or manager, defining the duration, objectives, and end-of-assignment terms, not the manager’s own employment status.

How do you know a transition assignment is over?

A transition management assignment ends, in practice, when the objectives precisely set at the start of the assignment are achieved: not on an arbitrary date disconnected from what is actually happening on the ground, nor indefinitely until the company finds a permanent solution. Three end-of-assignment scenarios come up most often. The first and most common: the baseline indicators precisely defined at the very start of the assignment (OEE, OTIF, cash, compliance rate) reach the target level, and a permanent successor (hired in parallel or promoted internally) takes over with a documented handover. The second: the initial crisis situation is stabilized, and the company decides not to maintain an external leadership position beyond that stabilization, with the existing team taking back control under a normalized way of working. The third, rarer scenario: the assignment reveals that a permanent position is ultimately not needed, the reorganization put in place by the transition manager being sufficient to durably cover the need initially identified.

Industrial transition management vs. generalist transition management

The generic term “transition management” actually covers a wide range of very different practices depending on the industry involved. In services or finance, an assignment often focuses on organizational or financial topics with no direct link to a physical production site. In industry, however, the operational dimension and daily direct contact with the shop floor or production line fundamentally change the real nature of day-to-day work: an industrial transition manager spends a significant share of their time on the shop floor, not only in management meetings. It is precisely this field specificity that justifies the existence of firms like MT-Transition, entirely and exclusively dedicated to industry rather than generalist: a distinction that, for an industrial executive, often makes all the difference in the relevance of the profiles proposed.

In practice, these three outcomes don’t always play out so cleanly: an assignment sometimes shifts from one scenario to another along the way, for example when a role initially meant to be temporary becomes permanent after the transition manager has proven their value on the ground. That is precisely why the assignment mandate specifies, from the outset, how each of these three outcomes will be recognized and documented.

How an industrial transition management assignment gets triggered

The most frequent triggers of an industrial transition management assignment actually follow fairly easily identifiable patterns: an industrial leadership position becoming vacant with no identified successor, a customer or quality audit revealing a drift that requires immediate reinforced oversight, a ramp-up that exceeds the site’s current organizational capacity, an external growth operation requiring rapid integration of a new organization, or a situation demanding stabilization before a permanent executive can be recruited with confidence. In nearly all of these cases, the common factor is time: the situation cannot wait for the five to six months of a traditional recruitment process, or the operational or financial consequences worsen every additional week.

The typical course of an assignment, from first contact to handover

The very first step is always a free, no-obligation phone conversation, which makes it possible to qualify the situation and confirm that an industrial transition management assignment is indeed the right response. Within just 72 hours, 3 targeted profiles follow, matching precisely the sector and function concerned: not a long list of generic applications to sort through entirely on your own, but an already narrowed selection of the most relevant profiles. Once the transition manager is confirmed, the actual start of the assignment generally takes place within one to two weeks, the time needed to finalize contractual aspects and organize the handover with the existing team. The first two to three weeks of the assignment are systematically devoted to initial diagnosis: measuring baseline indicators, mapping priorities, making the first quick decisions on the most urgent issues. The rest of the assignment then follows a regular, well-structured management rhythm, with formalized and documented progress points, right up to careful preparation of the final departure: a documented handover to the permanent successor, or definitive closure of the assignment once all objectives have been reached and validated.

Which roles are mobilized in industrial transition management?

The most frequently mobilized function in practice remains site management or, more broadly, general industrial management, but industrial transition management actually covers the full range of operational leadership positions: production management, supply chain management, procurement management, quality management (QHSE), finance management (CFO), human resources management (HR Director), information systems management (CIO), and general management for the deepest turnaround situations (CRO). Each of these industrial roles responds, in practice, to a sensibly different triggering logic, detailed on the dedicated pages of this site, but all share the same fundamental requirement: real, verified operational experience in the relevant industrial sector, not mere theoretical expertise acquired solely at a generalist consulting firm. The exact role does not need to be settled before the first contact: it is often by describing the situation (an observed symptom rather than a job title), that the right profile becomes clearest. An executive who is torn between several closely related functions, or who is not certain exactly which role is needed, generally gets a clear answer within a few minutes of conversation, without having had to decide alone beforehand.

Whether or not your situation matches one of these classic triggers, the principle remains the same: industrial transition management steps in precisely where time is too short for traditional recruitment, without sacrificing the quality of execution on the ground.
