In order to meet an increasing internal variety, a solution can be the modularization of products. To motivate modularization projects throughout all phases of life, different effects of modular product families were collected in previous works on a literature basis. In this paper, a validation concept is presented, which will investigate these effects by using statements directly from industry representatives. In particular, the industry background is included in the evaluation to generate a more differentiated overall picture of impacts of modular product families.
