How would you find out how writing works in your field?

I would probably ask somebody. I would ask a person in my field (My dad, for instance, who works at john deere developing software) how writing is useful, what you need it for, why you need it, and how often you have to write. Honestly, Software Engineering is a lot of writing. You write code, you write reports, you write memos to other team members. You write the documentation for your program so that the people that are supposed to use it can use it.
