Manufacturing processes in the Automotive Supply Chain are extremely complex and require the integration of internal and external sources. Finding information to decide on quality is an even more important problem. The application of knowledge graphs and defining Ontologies has changed the time to answer significantly like finding cars which are equipped with specific components. Prior to the usage of a knowledge graph, an army of employees went to the archives to find out where the components are installed. This took usually multiple days or weeks to find the right answer. With the new knowledge graph the answer is available in minutes and the OEM can be less conservative in the communications with its clients.
