This thesis researches the importance of knowledge management and communication pro-cesses with respect to daily work and learning in car workshops. First, specific aspects and interactions between knowledge, communication and skilled work in car service are presented. Furthermore, the theoretic concept and methods of knowledge management are introduced and discussed in the context of vocational and company-based learning processes. Second, the results of a web-based survey as well as case studies conducted in independent and manufac-turer-dependent car workshops are summarized. It becomes clear that the need for specific knowledge is dramatically growing, while car workshops are heavily dependent and rely on filtered knowledge of either car manufacturers or specialized diagnostic service providers. An interaction and collaboration between skilled-workers in car workshops could not be found or is at best informal. The found separation between working and learning hampers the exchange of information and expert knowledge dramatically. In consequence, available knowledge is wasted and learning by communication and deliberation does not happen. Therefore, in the final part of this thesis, a concept to implement car workshop suitable knowledge manage-ment, which would unleash the (currently still segregated) available potential is presented. In der Dissertation wird untersucht, welche Bedeutung das Wissensmanagement für das Arbeiten und Lernen der Fachkräfte in Kfz-Werkstätten hat. Trotz des hohen Informations- und Wissensbedarfs gibt es kaum einen Austausch der Kfz-Fachkräfte untereinander - auch Erfahrungswissen wird nur vereinzelt und informell gesichert und weitergegeben. Das belegen die empirischen Ergebnisse einer Sektoranalyse aus Onlinebefragung und Fallbeispielen. Auf dieser Grundlage entwickelt der Autor ein Modell und Perspektiven für die strukturierte Kommunikation und das Wissensmanagement zur Sicherung von Fach- und Erfahrungswissen im Kfz-Service. Preisgekrönt: Dr. Torben Karges wurde für seine Dissertation mit dem gtw-Wissenschaftspreis 2018 ausgezeichnet. Mehr Informationen unter wbv.de/bai.
