When working for a Norwegian company, but with colleague in all of Scandinavia, we where introduced to the notion that as Danes we tend to be a bit pushing, impatient and just wanting to get on with the job. This would clash with the Norwegians who would want to do a lot of prep-work, upfront documentation and generally follow a certain procedure. The Swedes would avoid starting something until very one on the project had been heard and their concerns addressed.

If this is completely true in all cases seems questionable to me, but we did complete a project faster than the Oslo office could plan and document an identical project in Norway, resulting in an audit from the head office.
