Are interim managers worth their money?

Daily rates between €1,100 and €2,000 for full-time work – over several months – are enough to make many a finance manager break out in a cold sweat!

From their perspective, this is understandable. However, the use of interim managers is often indispensable, as demographic change has already taken hold in most companies.
Experts in specific fields – with leadership experience, empathetic, highly communicative, and fully flexible in terms of geographical location – this is how the wish list for employees needed for the future of one's own company reads.
Unfortunately, this ideal increasingly resembles an unrealistic one that is hardly to be found on the open job market anymore.
In our experience, more and more experts with relevant skills want to dedicate themselves to temporary jobs (temporary assignments) with maximum energy and, after an assignment, have the time and freedom to regenerate.
In addition, a "TOTAL COST OF OWNERSHIP" analysis is necessary for such business cases:
Immediate availability and therefore no loss due to understaffing, no payroll taxes, no bonuses, no fees for recruitment agencies, no termination costs, deployment "on demand," and much more are important aspects when deciding between "searching for a permanent staffer" and "interim management."
