Identifying challenges and limitations of interface modeling in multi-brand product engineering processes

This paper addresses the increasing complexity of interfaces in multi-brand product development processes (PDPs). By conducting a systematic literature review and validating findings through industry expert workshops, we assess and compare existing modeling approaches. Seven criteria for effective interface management are derived and applied to model clusters. The results reveal that only integrated, multi-level modeling strategies can adequately capture technical, organizational, and governance challenges in multi-brand PDPs, highlighting key gaps and future research needs.
