This contribution aims to support the new development of modular product families by considering aspects of new product development and innovation. Various concepts and dimensions of innovation in relation to product development and modularity are examined. Based on the dimensions of external and internal variety and different degrees of novelty, the Product Family Innovation Matrix (PFIM) was developed to support the development of innovative modular product families. Four different change mechanisms were systematically compared and classified in the PFIM together with innovation approaches from the literature, resulting in a strategic support tool for the new development of modular product families.enInnovationModular Product FamiliesNew Product DevelopmentProduct Architecture DesignTechnology::600: TechnologyConference Paper10.35199/norddesign2024.27Conference Paper
