Once you become a doctoral candidate and begin completing your milestone documents, you will be required to submit something call a "Change Matrix". This is a table that notes each comment received on your writing, how you will address it, and where the issue is in the document. Note: You do NOT need to actually make these changes to your document this time. However, should you go on to further explore this topic for your dissertation, it is strongly recommended you consider incorporating this feedback.
It is also an opportunity to ask questions or disagree with feedback. Yes, I said disagree! Your eyes did not deceive you. You are working to become an independent scholar, which means you should be an expert in your content area(s). As you have experienced in your literature search, there are a plethora of studies, many reviews, and various different conclusions that have (and can be) drawn from all the scholarly work. In other words, it is normal to disagree and have scholarly debates. However, note the term scholarly debates. I emphasize this, because it is fine to disagree with another academic scholar, but your stance/opinion should be based in the scholarly literature (vs. simply your experience or feelings) and supported by specific data and information.
