Yet even more potential for reducing internal variety can be gained by even striving for carry-over across product families as industrial case studies showed. A holistic corporate product program strategy for reducing variety supports the identification and exploitation of this potential. How this strategy can be defined in specific corporate context is outlined in this paper. Based from the attributes of an ideal product program steps for definition of product structure strategies are proposed. The resulting development tasks need a deep understanding about a solution that suits corporate needs for differentiation and standardization best. This can be gained by analysis of tearing forces towards differentiation and standardization and comparison of possible solutions that enable commonality in different ways and by this have different effects. To support evaluation of these solutions a complexity cost estimation method is proposed complying with the lack of detailed information in the conceptual phase. © 2013 The Design Society, unless otherwise stated.enCommonalityPortfolio managementProduct familiesProduct programProduct structuringTechnikIngenieurwissenschaftenConference PaperOther
