Abstract Unplanned product-related engineering changes are a major field of disturbance for production ramp-up. Numerous of them can be traced back to deficits in design verification conducted during precedent product development. The present paper provides a conceptual methodology for planning design verification activities based on the quantification of uncertainties. By identifying and modeling information sources regarding the true value of a functional product characteristics, uncertainties regarding functional requirement fulfillment can be modeled in order to plan necessary design verification activities. The uncertainty modeling is based on the common ESReDA-framework as well as recent approaches using Dempster–Shafer theory.
