 All of these things need to be considered when we learn how to program.
 Because you do not just \inQuotes{program,} you develop software.
 Indeed, a good share of programmers usually spend only about 50\%~of their time with programming~\cite{T2019MOSWBFDHOT2TMOSS,AS2019DS2OSRP}.
+Other studies even arrive at less than 20\%~of the working time spent with coding, maybe with another 15\%~of bug fixing~\cite{MAGTOC2024EHFAP}.
 Of course, we cannot cover all other topics related to software engineering in a programming course.
 
 However, in typical courses, such aspects are ignored entirely.
