The usage of virtual assistants is starting to appear within a wide range of application areas. This thesis has been conducted in collaboration with Volvo Cars and more specifically the CAD & Mechanical Development department. It examines how a virtual assistant could facilitate daily product design work at Volvo Cars. This is done by creating a deep understanding of how Design Engineers currently use Volvo Cars CAD Methods or VM’s. The Volvo Cars CAD Methods are instructional documents where Design Engineers find guidance when encountering design related problems. This thesis focuses primarily on the mechanical design aspects of Volvo Cars CAD Methods. The final prototype presented in the thesis is a result of interviews, affinity diagram analysis, requirement analysis, survey, and design iterations. This thesis and the final prototype have shown the interaction design possibilities, limitations, use-cases, and future potential of a virtual assistant Volvo Cars.
