A method to assess the effects of engineering change propagation
This paper presents a modelling method that seeks to support the prediction and management of undesired engineering change (EC) propagation during the design and development of complex products. The method builds on the house of quality and the change prediction method to model the effects of potential change propagation brought about by different change options. The objective is to better reflect how well each change option can address the product requirements. The method was applied to the design of a jet engine fan during a case study with an aerospace company. The findings suggest that this modelling approach is suitable for assessing the effects of potential EC propagation and can support companies in effective exploration of the design space.
