6 Summary and outlook

German mechanical engineering is characterized by high-quality and innovative products with a wide range of configurations in order to offer customers the best possible solution. A study from 2012 shows that the number of variants more than doubled between 1997 and 2012 among the mechanical engineering companies surveyed. A study conducted by the WZL together with the VDMA and Roland Berger confirms that this trend will continue in the future. Here, 49% of machine manufacturers and 61% of component manufacturers stated that they expect the number of variants to continue to increase over the next few years. However, there is often a lack of efficient handling of the resulting complexity, with a study by management consultants A.T. Kearney estimating the complexity-related earnings reserves at 3-5%. The efficient creation of the differentiated offer required for this is supported by modular strategies that make it possible to create different variants of a product from the smallest possible number of building blocks. However, the design of such a modular product system is currently still often intuitive.
