For the development of innovative technical products specialised knowledge is becoming increasingly important. Knowledge can be transferred from external sources and company-internally between engineers. Internal knowledge transfer is gaining importance due to a growing fluctuation of engineers possessing specialised knowledge. To enable knowledge transfer between engineers, the knowledge has to be elicited and represented. However, knowledge elicitation and representation are time-consuming processes, since the engineers are often unaware of their knowledge and have to be guided through the process by a moderator. The aim of this work is to develop a knowledge mapping approach which enables the engineer to independently elicit and represent his knowledge. We analyse results from a case study and verify findings from psychology, knowledge management and technical product development. Based on this analysis, we combine elements from existing knowledge elicitation and representation methods to a 3-phases concept for independent knowledge elicitation and representation which does not necessitate a moderator.
