Why is it "surprisingly" useful?
I dont know what you meant by autonomous process...it is indeed a process which involves mutiple checks and balances, of time, resources, EGO issues, the sociology of intra-departmental equations, the wider sociology of academia, so forth...
I dont think you are to be producing papers this early in the process...planning well, that always helps, as far as I can comment...and writing, depends. For me, writing is my mode of thinking, so I write A LOT. some people make notes, others have stuff scribbled which hold pearls in them...
And you cant be well on your way to finishing a lit review 3 months into the process. It;s just impossible. So you are fine. Good luck.
