A KM system is a new species of communication and management system that is enabled by technology, is cognizant of information, and takes into account the complex nature of intangible assets, to support the flow of knowledge inorganisations.
If KM is ‘the management processes through which organizations increase the value they generate from their intellectual capital’, then a KMS is a system that enables organisations to generate increased value from their intellectual capital. Such a system may include an information technology application as a component of broader system.
