“…Oftentimes, users have to troubleshoot and learn software by themselves in the course of their regular working tasks (Kiani et al , 2020), as it is challenging to cover these rapid developments with formal training (Kiani et al , 2020; Harteis, 2022). Second, while standard curriculums have been successful in training employees in standard work practices, knowledge workers increasingly have to deal with “fuzzy tasks” (Harteis, 2022, p. 417), as well as complex and niche problems (Littlejohn and Pammer-Schindler, 2022). Thus, problem-solving is a central requirement for knowledge workers, especially when dealing with complex software tools, but, at the same time, problem-solving is also considered an important source of informal learning in the workplace (Rausch, 2013; Kiani et al , 2020; Tynjälä, 2013; Tynjälä and Häkkinen, 2005).…”
