When designers, engineers, product planners and others look for suitable modularization methods, they are overwhelmed by a large amount of differently documented information in the literature. Our contribution supports them in selecting a suitable modularization method without losing sight of the economic objective. For this purpose, modularization methods were analyzed regarding their module-forming steps to find out which reasons lead to module decisions. By means of module drivers of this module-forming steps, the link to the Impact Model of Modular Product Families (IMF) was made possible. The IMF presents the relationship between the levers of modularity and the resulting economic effects at all life phases. A generic method step description for the presentation of the module-forming steps was developed which enables the relevant information of the steps to be recorded quickly and easily. The method step description was applied to the module-forming steps of modularization methods, which allowed them to be linked to the IMF. The application of the description template enables the analysis, comparison and rapid selection of modularization methods with regard to their addressed economic objectives.
