The term -Knowledge Mapping- seems to be relatively new, but it is not. We have been practising this in our everyday life, just what we are not doing is - we are not documenting it, and we are not doing it in a systematic way. Knowledge Mapping is all about keeping a record of information and knowledge you need such as where you can get it from, who holds it, whose expertise is it, and so on. Say, you need to find something at your home or in your room, you can find it in no time because you have almost all the information/knowledge about -what is where- and -who knows what- at your home. It is a sort of map set in your mind about your home. But, to set such a map about your organisation and organisational knowledge in your mind is almost impossible. This is where K-map becomes handy and shows details of every bit of knowledge that exists within the organisation including location, quality, and accessibility; and knowledge required to run the organisation smoothly - hence making you able to find out your required knowledge easily and efficiently.

Great post dude, what you study?
