Knowledge management is a wide concept used for relating epistemology in a philosophical sense to the very practical area of exchanging data efficiently using ICT. Its breadth is mirrored in this e-book of Facilities. Sverlinger (2000) collected the ideas of scholars to generalise a concept of KM as a process of getting the right knowledge at the right time to the right people so it can be of the greatest value for the organisation. This is still highly relevant. The concepts of "data" and "information" are separate concepts to KM and are both required to develop and share knowledge. Today capacity for exchanging data has increased; databanks are usually on the web rather than stored locally. Data and information from various disciplines can now be compared with each other in order to check for relevance, and this has given rise to a need for KM. It is my belief that, in the future, KM per se will be an increasingly significant factor for both practitioners and researchers in FM.
