This means that within the next years fewer engineers have to cope with increasing volumes of data and information in a more and more complex operational environment and the permanent loss of accumulated knowledge of the retiring experts. The work suggests that a solution lies in the focus of knowledge management{\textquoteright}s efforts on the level of information technology (IT).
