Virtual development has been established as an important tool in the product development process. Virtual Reality (VR) - as a part of the virtual development - offers the potential for a fast product visualization and interaction, especially during early development stages. The VR-based visualization offers the potential for early error detection and leads to a reduction of cost-intensive product optimization at a later stage of the development process. However, virtual models are yet not suitable for every task of the development process. In order to improve the effectiveness of virtual models, a technology-driven development of VR took place in the past with no or just a rudimentary focus on the user and his tasks during the product development process. Based on the identified deficits, a process model was developed in this thesis with the particular goal to evaluate the usability of VR to support specific automotive-oriented tasks, focusing on the user and his needs during the product development process. The model contains the analysis of the VR-work system including the identification and classification of barriers for the usability of the system, specific improvements of the tools and a final evaluation of the specific task as well as the whole VR-work-system through certain evaluation criteria. The model is verified by a case study focusing on the scope Validation of the quality and the 'look-and-feel' at a car manufacturer. The mentioned case study covers an analysis of the main components of the VR-work-system, identifying the main task which is represented by 21 subtasks, solved by the evaluation of 5 different work-items. During the evaluation 12 barriers were identified, which reduce the usability of the VR-work-system. Throughout the step 'improvement of the work-system', one barrier was eliminated. The final evaluation showed that certain improvements regarding the visualization, the interaction and the information density of the virtual scene have to be brought. Therefore, specific suggestions are given in order to improve the usability of the VR-work-system. Due to its generic approach, the developed process model can be adopted to other scopes within the development of automotive or other industrial products.
