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.
