This paper introduces an approach which uses a modified House of Quality (HoQ) and the Change Prediction Method (CPM) to consider change propagation during the concept selection phase. The key idea is to capture the influence of unintended feature changes on product attributes which arises due to component change propagation, and present this information as an aggregate performance rating for each product attribute. The results from the case example indicate that the performance rating of product attributes can be different once change propagation is taken into account. The findings in this paper also provide an indication that ignoring change propagation in concept selection can result in project delays due to unexpected changes.
