meaning: how one goes about it?

Hi, I listened to the dialogue where the interviewer asked a question: ‘So thinking about your research and how one goes about it, what’s the value of a literature review and why do we do one?’

I wonder what the phrase ‘how one goes about it’ means.

How someone goes about completing a piece of research.

According to oxfordlearnersdictionaries.com, the phrasal verb ‘go about’ has several meanings. Does it mean ‘to keep busy with something’ in this context?

Before someone gives more accurate definition, to me it sounds close to ‘approach’ there. The closest I found in dictionaries was ‘dealing with a problem, situation, or job in a particular way.‘
I believe you could read it: ‘So thinking about your research and how to deal with it\treat it [in the broader context], what’s the value of a literature review and why do we do one?’

Thank you, Eugene2114!
