Telecom Computer Security Databases Handheld Devices Tech. Your comments, I think, are focused on trying to associate management with knowledge. Those best practices they put in a database are the artifact of of knowledge process that produced them. People will often have difficulty getting same outcome with the best practice because it is being used outside the context of the knowledge process that produced it. Also I like to use the word coaching versus mangement when discussing knowledge because it helps me define the role you can play in assisting.
Management carries with it a strong conotation of control.
A knowledge process resents control but accepts coaching. I think you can start small as long as you have someone who keeps thing from going dormant and prods you to share your thoughts with other members. I saw some metric on the knowledge ecology site which I believe recommmended you get to 24 active participants on a site.
