Abstract: In this paper, a new approach for the involvement of the voice of the customer in product innovation projects is discussed by using an example of automotive concept design. Today, a company's competitiveness is directly linked with its ability to innovate. At the same time, many product concepts fail in the market, as they do not satisfy customer requirements. Concurrently, the aim of this paper is to design a process that monitors the customers' needs throughout the product development process and allows to translate those requirements into measurable development targets. A literature review deems the traditional development of specification sheets to be static and superficial. Specification sheets often display a generic customer request, however, fail to convey the subliminal customer needs. On the other hand, customer-centred methods (e.g., Design Thinking) allow a deep understanding of those needs but lack their translation into the tangible language of engineers. Therefore, the target of this paper is to close the gap between the two approaches leveraging an adapted and iterative version of the Quality Function Deployment methodology. For this purpose, a three-step study is conducted. Firstly, requirements for the process are collected with the help of experts from the fields of technology, business, and human values. Secondly, a new process model is developed in workshops with experts. In a third step this new process is evaluated through expert feedback. As a result, a new process is presented for identifying, weighting and quantifying future proof product requirements.
