Use Cases

Our Offer

And how we can support you in your individual situation

Fill vacancies

One of your top executives is unexpectedly unavailable, whether due to illness, accident, dismissal, or parental leave. You neither want to return to day-to-day operations yourself nor overtax the remaining leadership. Bring an experienced interim manager to your side who will take over the position quickly and competently.

Implement projects

Your leadership crew manages the day-to-day business successfully, but a special strategic project lies outside their core competencies. Whether it is a change of location, a product launch, or a new ERP system – provide your team with a specialist who has already successfully handled such projects multiple times.

Shape change

For the digitalization of your business model, you need new thinking and external expertise. Get an experienced change expert on board who, together with your management, plans and implements the transformation project and takes responsibility for its successful completion.

Case Study: A company loses its CFO at short notice

Problem: Reporting collapses, banks demand clarity, management is flying blind. How we help: An experienced CFO stabilizes liquidity, establishes weekly reporting, and creates transparency for owners and the leadership team within a few days. The organization regains security – until the permanent replacement takes over.

Case Study: ERP implementation project threatens to fail

Problem: Milestones are missed, internal teams are at capacity, the implementation is losing structure. How we help: We provide an interim project manager with ERP experience who reorganizes the project, sets clear responsibilities, and steers the implementation with a high cadence. After a few weeks, the project is back on track – and goes live successfully.

Case Study: Growing company must make structures fit

Problem: Responsibilities are unclear, decisions take too long, teams are working at cross-purposes. How we help: An interim change manager accompanies the transformation: they create role and process clarity, establish a functioning leadership routine, and anchor new behavior in day-to-day operations. After a short time, the organization is noticeably more stable, faster, and better coordinated.

The Invest

Interim Management is too expensive for you, you say?

We see it rather as an [investment that pays off].

In the UK, Benelux, and Germany, interim management has long been a common model for the temporary reinforcement of existing management teams and for increasing the success of numerous companies – with a positive ROI. Many companies in Austria initially question the financial expenditure for interim management. We at ISG understand this reluctance and meet it with complete transparency. Therefore, together with you, we analyze the actual and hidden costs of unfilled positions and contrast these with a professional interim solution. Free of charge and completely non-binding. Our decades of experience from hundreds of projects in a wide variety of industries confirm time and again:

Usually, specialized expertise pays off [from day 1].

FAQ

What differentiates ISG from other recruitment consultancies?

At ISG, you benefit from the long-standing market knowledge of our consultants, direct access to a strong network of experts, and tailor-made solutions – even for particularly demanding interim vacancies. For us, you are not just an anonymous number: we personally take the time for your concerns and accompany you individually and in partnership throughout the entire process.

Which services does ISG offer?

Our focus is on interim management – we fill leadership and expert positions on a temporary basis quickly, precisely, and with the right cultural fit. Furthermore, we support companies with project staffing, the development of talent pools, and targeted HR consulting. Thanks to our affiliation with ISG, we can also provide support beyond interim needs if required – for example, in executive search and the permanent placement of key positions. This way, you receive everything from a single source: flexible, personal, and with the highest quality standards.

What exactly is Interim Management?

Interim management means that experienced executives or specialists are integrated into a company for a limited period – usually for several months, often significantly longer. They take on temporary responsibility, e.g., for vacancies, during transition phases, for projects, or in crises. The unique advantage: Interim managers are ready for immediate deployment, bring an external perspective and a wealth of experience, and deliver measurable results quickly without long-term onboarding. You only pay for the hours or days actually worked.

Why do I need an Interim Manager?

An interim manager brings immediate relief – for example, during personnel bottlenecks, transformation projects, crisis situations, or when specialized know-how is needed at short notice. They onboard quickly, think like entrepreneurs, act independently, and deliver solution-oriented results on a temporary basis – without lengthy induction or long-term contractual obligations. This makes interim management particularly flexible, efficient, and effective – exactly when you need it. Interim managers deliberately operate outside the internal corporate pecking order – freely and pragmatically.

How much does an interim manager cost and how does the billing work?

For the assignment of an interim manager, a customary market hourly or daily rate usually applies, which depends on the respective function, experience, and complexity of the assignment. These costs are 100% transparently known to you during the selection process. Billing is handled directly through us – so you only have one contractual partner and do not have to worry about administrative matters. You pay a monthly fee to us based on the manager's internally verified time records – we take care of the rest: contract drafting, payment of the manager, and support throughout the entire mandate.
