The overall goal of the research is to produce a Design for X (DFX) method which can be used to increase the commonality in the product family. The research presented in this article is based on commonality index calculation methods known in the literature. These methods are used to measure the existing commonality and to identify the components with highest influence to the commonality. From the commonality point of view results of three methods (CI, TCCI, PCI) have high values regardless of the used method. The commonality index calculated on the product family level does not identify how the components influence on the commonality. Therefore the calculations of commonality index should be applied on the function levels to identify the components which have the greatest influence in the value of the commonality. The study made to the case product family during this research bred two different kinds of new architectures. The first one was structurally similar to the existing one but it had major enhancement in the part level. The second one was essentially a new concept of the product family. It actually increased the number of parts per product variant but when considering the whole product family the new architecture reduced the total number of components.
