I studied computer science, that's why the term "Separation of concerns" is common for me.
I read the wikipedia article: https://en.wikipedia.org/wiki/Separation_of_concerns
Now I am unsure. Up to now I thought this term gets used outside computer science, too.
I thought it is a general principle to answer the question "who is responsible for what?".
Can you use the term "Separation of concerns" outside computer science to answer the question "who is responsible for what?"?
