Personal Knowledge Management is a smorgasbord of principles, concepts, disciplines and tools that we can all apply as knowledge workers in the new knowledge economy to help improve our ability to meet our personal and business objectives. It is taking responsibility for what you know, who you know – and what they know. It is “helping individuals to be more effective in personal, organisational and social environments”, often through the use of technology such as networking software. It is a bottom-up approach to knowledge management (KM), as opposed to more traditional, top-down KM.
