> Swiss world of rules makes the northern Germany feel as flexible as a South American country

That is quite unworldly. I worked on large projects both in Switzerland and in Germany. These are totally different cultures. The number of laws and the degree of bureaucracy in Germany is many times greater than in Switzerland (only surpassed by Italy). In Germany everything is forbidden that is not explicitly allowed, in Switzerland it is the other way round. In Switzerland everything can be negotiated; try negotiating with a German official. Good luck with that.
