Products in engineering design are susceptible to be changed. A change in one product element can involve changes in other elements. While, in most cases, the change impact can be partly predictable, unexpected propagation of the change can occur. The main objective of this work is to characterise this change impact in order to predict as finely as possible the consequence of the product change on its structure and its functions. We develop a process to explain how to use regression analysis to identify the type of dependency existent between two dimensions. Findings show that, although qualitative dependency, already used in the literature, aids to predict either the increase or decrease of the affected dimension’s value after a change in instigating dimension’s value, functional dependency offers an effective way for characterising the relationship between two dimensions and translate it into a function which can be helpful in the further works of change propagation analysis.
