+One of the services a centralized RSE department likely will provide is training to improve the often low-quality code developed by beginners ~\autocite{Ostlund2023}.
 Examples of organizational training efforts are the Helmholtz HIFIS group [https://events.hifis.net/category/4/], the Scientific Software Center in Heidelberg [https://www.ssc.uni-heidelberg.de/en], the Competence Center Digital Research in Jena (zedif: [https://www.zedif.uni-jena.de/en/]), and the SURESOFT workshops series in Braunschweig ~\autocite{SURESOFTLink, Blech2022}.
 Another national pioneer is the Göttingen State and University Library which set up a group of RSEs offering – besides training – services like data modeling and visualization, digital editions, portal development and more. They reported a remarkable increase in software quality, better grant applications, less brain drain and overall employee satisfaction levels~\autocite{schimavoigt2023}.
 The demand for such services appears to be ever-increasing.
