Areas of expertise


We can support your immediate need for interim management. The search for the right management team often takes time which is not always available. Instead of settling for the second best, it may help to work with us as interim management. Dr. Krehl has long-term experiences in the fields of automotive supply, mass production of components and systems with the zero defects philosophy under ISO TS 16949, development and technology transfer (see profile and achievements, Link).

Succession planning

Succession planning and execution sometimes makes an interim management necessary. We can help you not only with the appropriate interim management but also with the succession process monitoring, the set up of advisory boards or even the assumption of board mandates.

Advisory board mandates

We are available to take over board mandates. Board mandates require experience in the business, management experience and a strong network of contacts. This is what we can offer.

Strategy definition, strategy execution, strategy review

Basis for a company strategy are clear company goals – a vision. Strategy is not only preparing for but also against certain circumstances. Strategy development has to follow certain rules. It is often difficult doing this within the daily business. Performing SWOT analyses, developing USPs and planning how to be more successful than the competitors takes efforts from all levels of employees. To do this in a methodic process the involvement of MTSG Consulting can help to perform all the right steps.

Follow the customer to foreign countries, definition of starting conditions, technology transfer, startup abroad

Globalization of manufacturing companies is often expected by their automotive customers. Simply relocating a manufacturing company into a low cost country is not globalization. A truly globalized company is competitive (also with global competitors) in all areas where it is active. So the first step to globalization is to adjust manufacturing cost and/or product portfolio in the home market to a globally competitive level. Only after achieving that the next steps like opening manufacturing sites in other areas of the world can be considered. Customers rightfully expect the same processes and the same quality around the world. The transfer of technology in such new locations has to follow certain rules as well as be performed with all consequences. The use of expats for a limited time is often unavoidable. This requires a consequent and transparent personnel development and planning. So globalization has a lot of different aspects. MTSG Consulting can support you in such activities.
