Some words were confusing or problematic for the testers.
On the one side, people understood “Open feedback” as something “public” and “closed feedback” as something “private”. These words were changed for “comments” and “scores”, respectively. Later, the word “scores” was changed by “team assessment” for a better understanding.
On the other side, “One on one” was changed by “one to one”, because the former, reminded the user to a “fight”, which was exactly what I didn’t want to cause.
