Good business communication is something you only learn by /doing/ it. Expecting a course to facilitate that is flawed. I'd be all for increasing the roles of internships in CS education in order to accomplish that -- and I have noticed that's begun to happen as well. CS majors these days have internships lined for summer and winter if not more (especially due to COVID). I am sure they'll learn a lot more than I did during that era of my life just by sheer osmosis.
If it is a good course on business communication they _should_ be doing it - in class. And getting feedback and suggestions on improving with every attempt.
Internships are a wonderful thing but many people don't realize how they are coming across so don't look to improve. There is some learning by osmosis, but mostly people keep doing what they have always done because it works (as far as they can tell).
They won't be doing it, they will be doing a simulation of it. How are they going to learn business communication without doing it in the context of a real business with a real P/L line and real consequences for good and bad execution?
