Harold, I agree fully with the fact that knowledge cannot be managed - it is what is in people's head, that is why I moved to talk about Knowledge Flow Management instead. What gets transferred is information only, and knowledge can get (partly) re-created at the receiving end. But as it is within a different frame of reference and experience it will always be different. The notion of flow management is about creating the conditions that make it more likely the flow can happen, by for example removing certain barriers (like the stones in a river) one-by-one to make it easier. To expect that this flow becomes easier by just offering technology is the No.1 reason why initiatives in this area fail. It needs facilitation and real attention to the human factors at multiple levels of the organization.
