Six Sigma is a development methodology which emphasizes objective evaluations based on facts and measurements. However, for some problems the information is inherently subjective, with large individual variations. Also, in the early development phases, it may be difficult to define measurable metrics that correctly capture the important qualities. The vehicle HMI is a good example of such an application. In this paper, we present experiences of applying Design for Six Sigma methods to the early development phases of an automotive HMI. The focus of the paper is on how to handle uncertainties and vague subjective information.
