The hottest management theory for the new millennium is knowledge management.
There are many publications, seminars and theories on the subject but we still don't really know what it is. We know what it isn't: it has nothing to do with IT (data isn't information and information isn't knowledge).
It's not what the 'knowledge-holder' knows, it's what the recipient knows (or wants to know). It is no way to investigate mistakes, or to capture original ideas. It has no effect on morale or motivation. There are lots of ways of managing knowledge, but managers find the written word hardest to cope with. Don't worry - leave writing to the experts. Jesus, Socrates and other great figures from history never wrote a word. Even Goethe had a secretary.
