About Michael

About me

Do you need qualified support in production or logistics at short notice to stabilize processes, increase performance, or master specific manufacturing challenges?

I am a freelance Interim Manager and Lean expert with over 20 years of industry experience, ranging from manufacturing management and Lean programs to international site development.
As a certified Lean Six Sigma Black Belt, I support medium-sized companies with operational challenges, process improvements, and temporary bottlenecks – hands-on, structured, and with a clear goal.

I bring leadership experience from series production, mechanical engineering, and automotive sectors, and have successfully managed projects both in Germany and internationally (e.g., Turkey).
My focus is on practical implementability, clear key performance indicators (KPIs), and measurable added value – with an eye for technology, processes, and people.

Competency areas
- Interim Management Production / Logistics
- Lean Management / Six Sigma (Black Belt)
- Shopfloor Management & Process Visualization
- Value Stream Analysis / Layout Optimization
- Development & Implementation of KPI Systems
- Change Management & Team Coaching
- SAP R/3 · SAP Business One · Solid Edge · MS Office

I think solution-oriented, act entrepreneurially, and remain pragmatic.
Think Lean. Optimize. Implement.

Let's get improvements rolling together.
Let it flow.
