Technological advancements regarding functional capabilities of products affect product development processes. We observe the following: More functionality can be included in smaller devices. New devices are invented as hybrids between existing devices. Products can be individually adapted for end customers. Although the current product development processes already include contextual information about target customer groups and scenario of use, this information is strongly linked to single devices. We present a hierarchical superstructure above devices regarding functional capabilities able to categorize devices by functionality but also recommend devices for a set of functionalities.
