The differentiations can be obtained by adjusted and new features. The current product portfolio of a company is usually used as a starting point to develop and plan descriptions of future products with differentiating features. A product road map is often used in this context. This contribution investigates whether the targeted differentiation of future products in such descriptions can be increased by varying the origin of the reference system elements. Reference system elements (RSE) are the elements which stem from other existing or planned systems and form the basis of the development of a new product. Long-term product properties can be identified by using forecast methods like scenario analysis. Albers et. al and Marthaler et. al developed an approach that allows the development of crossgenerational product roadmaps [D, P]. This approach focuses on the analysis of a current state, a derivation of a target state and the development of a roadmap through a Key Performance Indicator (KPI)based delta analysis. These KPIs are the need for change and the environmental robustness. Need for change is indicating the delta of the reference and the scenarios the robustness is indicating the weighted relevance of properties within the scenarios. Five experiments with different shares of RSE sources have been conducted. A correlation between the RSE and the innovation potential and engineering effort is identified. This experiment shows that the general tendency of the experiments is to have medium need for change and low robustness while some of the experiments do behave with patterns. They show that there is clear impact of the RSE sources on the robustness and need for change regarding the different product properties. This approach supports developers in the development of new products, by guiding them when choosing appropriate reference systems.enEngineeringConference PaperConference Paper
