Do we need a definition ?

Strange... when confronted with the term Knowledge Management everybody starts asking for a definition and I assure you there are loads out there. So take your pick.
Two simple words we use in daily life but when they are put together we have a discussion on our hands. Not strange... people claim, "How can I act on something which is not defined ?"
O.K. so here is one;
Knowledge Management or KM is a professional discipline applied to concepts and technologies used for the systematic collection, transfer, and management of tacit and explicit information within individuals and/or organisations.

I bet you still wouldn't have that "aha .. thanks I've got it" feeling, turn around and start "doing" KM.
If we talk about process management, quality management and managing organisations, no definitions is asked. You just walk away and start re-engineering processes, enforcing quality and re-organise organisations. No puzzled faces as if you've just seen a ton of bricks hanging in mid air.
If asked for a definition of any of those words, most people can't give a clear cut definition and if they can they are all different.

So do we need a definition ? No we need an understanding.
