Product models are the results of product modelling and are used for decision making during the development process. They are based on assumptions by the designer, which are made under a lack of information, so the designer has to make assumptions under uncertainty. This paper systematizes the process of product modelling to assist understanding of what the designer do during that process. With the help of that, a methodical support is developed which the designer can use to define a viewing frame for the product model. It is based on the function-process relationship and the question, in which way the product behaves if identified influencing factors occur.
