I work for a multinational corporation. We have hardware developers in several EU countries. Moving prototypes and parts among the various countries is a paperwork nightmare. And we are expected to manage it. That's right. We engineers are instant import/export experts.
It works about as well as you might expect it to. And, between the parcel companies and various countries' customs, it takes ages. Not accounted for in the schedules, of course, because that would show that our multinational development effort is far less efficient than our corporate overlords would like to think it is.
