How will I set the boundaries of the literature? What are my rules for considering an article fit for review?
What are the credentials of the authors of the sources I choose? Are their arguments supported by evidence?
Are the authors subjective? Did they consider both supporting and contrary data?
Have I included sources that offer alternative interpretations, or have I only chosen sources which validate my assumption?
Does the source contribute to the understanding of the topic?
How do these sources relate to my research question?
