Last updated: April 2026
What does interim management mean?
Interim management means hiring an experienced, external executive on a fixed-term basis — typically 3–12 months. The interim manager takes full operational responsibility, leads teams, and implements changes hands-on. The model is especially suited to situations where a company needs experience quickly, without a lengthy recruitment process.

Interim management by the numbers
How does an interim engagement progress?
Initial assessment
In the first week I map out the current state: processes, teams, challenges, and goals.
Plan and priorities
I identify the most critical areas for improvement and create a concrete action plan with a timeline.
Execution and leadership
I lead daily operations, implement changes, and build performance metrics to track results.
Handover and continuity
I ensure a smooth transition to a permanent hire or the organization. I document processes and ensure knowledge transfer.

What does interim management mean?
Interim management means hiring an experienced executive on a fixed-term basis — typically 3–12 months. The interim manager takes full operational responsibility and leads daily operations, just like a permanent executive, but without a lengthy recruitment process.
How does an interim manager differ from a permanent executive?
An interim manager brings experience from multiple companies and situations, starts quickly (1–2 weeks), and focuses on delivering concrete results. A permanent executive commits long-term and builds deep organizational knowledge. Interim fits acute situations; permanent suits long-term needs.
How quickly can an interim manager start?
Typically within 1–2 weeks of the first conversation. This is a key advantage over permanent hiring, which takes an average of 90–120 days.
How long is a typical interim engagement?
Typical duration is 3–12 months depending on the situation. Shorter engagements (3–6 months) suit bridging situations; longer ones (6–12 months) suit transformations. Engagements can also be structured as part-time.
How does an interim manager differ from a management consultant?
An interim manager takes operational responsibility and leads daily operations — makes decisions and implements changes. A consultant analyzes, recommends, and reports, but execution remains with the company's own leadership. The difference comes down to one word: accountability.
What does interim management cost?
The cost of interim management depends on the scope, duration, and intensity of the engagement. The investment is typically smaller than the cost of a mis-hire, and an interim manager delivers results from the first week. Reach out and let's discuss your situation.
When does a company need an interim manager?
Typical situations include: a key person leaving, rapid growth requiring more experienced leadership, a transformation or restructuring, bridging during a permanent search, or the need to bring outside experience into a critical phase.
Is interim management suitable for SMBs?
Yes — often growing SMBs benefit the most. An interim manager brings the structures, processes, and experience the company doesn't yet have. The fractional model (part-time) makes interim management accessible for smaller companies too.
What is a COO — Chief Operating Officer?
A COO (Chief Operating Officer) is responsible for a company's day-to-day operations: leading processes, coordinating teams, and ensuring operational efficiency. The COO typically serves as the CEO's right hand, ensuring strategy is executed in practice.
What does a COO do in practice?
A Chief Operating Officer leads the company's daily operations: optimizes processes, manages teams, builds performance metrics, and removes bottlenecks. In practice, they ensure the company's strategy translates into concrete results and the organization runs efficiently.
