Today I was reading an article in EContentMag.com titled--Knowledge Management Involves neither Knowledge nor Management--by Martin White.
Among other things, Martin writes about Dave Snowden's three rules for knowledge exchange:
"Knowledge can only be volunteered; it can't be conscripted."
"People always know more than they can tell, and can tell more than they can write."
"People only know what they need to know when they need to know it."
