Definition

What is an Interim Expert?

A professional recognised for mastering a rare skill, a specialised know-how
or a specific technology, engaged for a fixed period
to bring their expertise to a precise topic

Interim Expert: a MANAGERIM differentiator

An Interim Expert steps in when an organisation needs a highly specialised skill that does not exist (or not in sufficient depth) in-house: the early phase of a strategic project, accelerating an R&D programme, developing new products or services, exploring new markets, diversification or strategic pivot, technical due diligence for an investment fund, upskilling of teams.

An Interim Expert does not necessarily manage teams, but supports them with an outside perspective, technical excellence and situational intelligence built on years of experience on cutting-edge topics. MANAGERIM develops and runs, across Europe and internationally, a private network of Experts organised by sector and discipline verticals: engineers, scientists, researchers, PhDs, academics, physicians, Qualified Persons (QP), and executives who previously led ambitious technology programmes.

FAQ

Everything you need to know about Interim Experts

Answers to our clients' most frequent questions
about deploying Interim Experts

What is an Interim Expert?

 
An Interim Expert is a professional recognised for mastering a rare or highly specialised skill, a precise technical know-how or a specific technology. Engaged for a fixed period (from 1 day to 18 months), full-time or part-time, they work on R&D, innovation, strategic or technical assessment, early-stage strategic projects, major projects, due diligence or training.

What is the difference between an Interim Expert and an Interim Manager?

 
The Interim Manager leads and manages: they take on an operational or leadership role within the organisation chart, mostly full-time. The Interim Expert brings a rare, highly specialised skill on a precise topic: they act as an expert advisor or project contributor, often part-time. The two solutions are complementary and can be combined on the same programme.

What is the difference between an Interim Expert and a consultant?

 
A consultant usually works with the methodology and teams of their consulting firm to produce recommendations and deliverables. An Interim Expert is deployed for their own rare expertise: they join your project, work with your teams, challenge your technical or scientific choices and transfer their know-how to them.

When should you bring in an Interim Expert?

 
Seven main contexts: (1) R&D and scientific research, (2) innovation and new products or services, (3) strategic or technical assessment, (4) early-stage strategic projects (diversification, pivot, new markets), (5) major projects or complex programmes (mega-projects, Gigafactories, defence programmes), (6) due diligence and independent expertise for investment funds, (7) training and upskilling of teams.

What expert profiles does MANAGERIM deploy?

 
MANAGERIM relies on a dedicated pool of more than 10,000 Experts: senior expert engineers, PhDs, scientists and researchers, academics and emeritus professors, specialist physicians, Qualified Persons, R&D and Scientific & Regulatory Affairs experts, certified sector experts (nuclear safety, BIM, Lean, Food Safety, HSE, ISO), AI, Data & Cybersecurity experts, and executives who previously led ambitious technology programmes.

Which sectors does MANAGERIM cover with Interim Experts?

 
The pool of more than 10,000 Experts covers strategic sectors such as construction, infrastructure, rail, energy, utilities, materials, defence, aerospace, high tech, electronics and telecoms. It is organised into 7 sector verticals: Industry 4.0, Advanced Materials, Tech & AI; Healthcare, Pharma & Life Sciences; Energy, Environment & Decarbonisation (including nuclear, offshore wind, hydrogen); Construction, Infrastructure & Smart City; Transport, Mobility & Rail; Defence, Aerospace & Space; Agriculture, Food & FoodTech.

What are the engagement terms: duration, full-time or part-time?

 
Terms are fully tailored. An assignment can last from 1 day to 18 months, full-time (full immersion) or part-time (a few days a month over time). An expert opinion can be delivered in a few days; R&D support can span several quarters.

How quickly does MANAGERIM present an Interim Expert?

 
MANAGERIM usually presents 1 to 2 profiles within 48h to one week, depending on how rare the required skill is. The assignment can then start within a few days, once the service agreement is signed.

How does MANAGERIM identify the right Expert for my challenge?

 
Identifying and deploying the best Experts, including for the rarest skills, is our core business. We activate our dedicated pool of more than 10,000 Experts, organised by sector and discipline verticals, and extend the search to academic, scientific and industrial ecosystems when needed. Every profile is assessed by our Talent & Business Managers: interviews, reference checks and fit with your context.

How much does an Interim Expert cost?

 
At MANAGERIM, the daily rate of an Interim Expert typically ranges from €1,000 to €1,700 excl. VAT, depending on how rare the profile is, the specificity of the skill, the duration and the engagement format. The assignment is billed on a time-and-materials basis: only days actually worked are invoiced. This cost should be weighed against the expected return on investment and the cost of inaction: delayed innovation, a wrong technology choice, incomplete due diligence.

Which groups have MANAGERIM Interim Experts worked for?

 
MANAGERIM Interim Experts have notably worked for groups such as EDF, Vinci, Framatome, Engie and Orange, on technical expertise, major projects and support for strategic programmes.

Are Interim Experts senior experts?

 
Yes. Interim Experts are recognised senior experts with long careers in their field: engineers, PhDs, technical executives, scientists. Some of them are alumni of major groups, still active or recently retired, who put their know-how to work on new projects and ensure the transfer of knowledge to teams.

How are confidentiality and intellectual property protected?

 
Every assignment is governed by a B2B service agreement with MANAGERIM, covering the confidentiality of information exchanged and the intellectual property of the work produced. You have no HR administration to handle.

What is a dedicated Expert community for a large group?

 
For some Key Accounts, MANAGERIM structures and runs a private community of Experts specific to the Group: Group alumni (executives or experts), pre-qualified independent professionals, academic and scientific partners. The Group preserves and transfers its know-how, deploys these Experts on demand, and MANAGERIM handles contract management and reporting.

Can an Interim Expert carry out technical due diligence for a private equity firm?

 
Yes. For private equity firms, MANAGERIM deploys Experts who can lead the technical due diligence of a target: assessing proprietary know-how, industrial maturity and scalability, and providing an independent expert opinion. After the acquisition, the same Expert can support the industrial scale-up of the portfolio company, for example moving from pilot scale to full industrialisation.

In which countries does MANAGERIM deploy Interim Experts?

 
MANAGERIM deploys Interim Experts across Europe, in all regions of every major market, including Austria, Belgium, France, Germany, Ireland, Italy, Luxembourg, the Netherlands, Portugal, Spain, Switzerland and the United Kingdom, and beyond Europe, in more than 30 countries. Experts can also work remotely on some advisory or assessment assignments.
