What are the best tips for developing a framework to write a (systematic) review paper?
I too find it frustrating that so many literature reviews are so unsystematic.

There are efforts underway to improve the quality of reviews, and to develop these skills in early-career researchers. We like our students, where possible, to write a review article as a early part of their PhD. The medical field has for many years been honing the quality of reviews, and there's much that other fields can learn from it.

We have had a Q&amp;A about systematic reviews earlier, and there I listed three relevant books. The most significant of these, as far as your question is concerned, is Doing a Systematic Review: A Student's Guide - Angela Boland et al - it's primarily aimed at Masters students, and also makes for an easy-to-read introduction to the field for anyone.
