One of the essential goals of technical product changes is to rectify unwanted but nonetheless occurring product defects and deficiencies after series approval. Based on feedback from production and service, as well as in response to customer complaints, the process for error correction is initiated. Due to the already advanced lifecycle after series approval, late product changes are associated with comparatively high costs. Nevertheless, economic considerations are often not conducted, as the impacts associated with a product change are numerous and difficult to capture. This issue becomes even more relevant in the context of hybrid products. In machinery and plant engineering, tangible goods and full-service packages are often sold bundled together.
