"Personal knowledge management is the only solid foundation of organizational knowledge management (KM). Without PKM, there is no KM, just databases of (mostly) unused information. Only individual knowledge workers can transcend the divisions between work teams, communities of practice, and social networks. Individuals connect these entities through their participation in them.
"PKM is the active process of being cognizant of our networks and engaged in our communities, while still working with our teams. These teams, and the organizations they work in, have an opportunity to harvest some of the PKM knowledge artifacts of their members. "
