> Nearly all employees have studied at a university, so the people are very used to writing texts (papers, seminar papers, lecture notes, thesis, ...).

I wish. Most people I've known in universities seem to read and write the absolute minimum to get by.

But I tend to agree that writing is preferable to meetings in most cases. I want to try out a policy that all meetings of more than two people must produce a written artifact, or clarifying edits to an existing document, that explains whatever ambiguity required a meeting to clear up. But you also need people to read. People don't read.
