{Excerpt} Networks of people who work on similar processes or in similar disciplines and who come together to develop and share their knowledge in that field for the benefit of both themselves and their organization. Communities of practice maybe created formally or informally, and members can interact online or in person. Knowledge activities that have been identified as most widely used by an organization, often also called the knowledge life cycle or the knowledge value chain. They are to identify, create, store, share, and use knowledge, often in a two-way exchange. Two important requirements have to be fulfilled to achieve improvements from these activities: (i) the activities should be aligned or integrated into business processes; and (ii) the activities should be balanced in accordance with the specificities of each process and organization. A knowledge management solution should not focus only on one or two activities in isolation.
