Every individual, team, and company is part of a business ecosystem, is a participant in customer-supplier relationships. We receive something. An input. We add to it. Hopefully our contribution is valuable. We then pass it along.
These relationships typically are internal to the company. Very few of us have direct access to external customers or to external suppliers.
But the approach a national culture takes to business relationships is the same whether they are internal or external to the company. And that approach is based on a logic shared by both the customer and the supplier. For in all business relationships we are either customer or supplier.
The question is, do Americans and Germans take the same approach? Does the American approach work with Germans? Does the German approach work with Americans?
If the logics are not the same, and if German and American colleagues are not aware of the differences, they will damage critical business relationships in a very short period of time.
