Note that such discussions may have either substantive [a potential new policy], theoretical [a potential new understanding], or methodological [a potential new way of analyzing] significance.
Be specific about the methodological approaches you plan to undertake to obtain information, the techniques you would use to analyze the data, and the tests of external validity to which you commit yourself [i.e., the trustworthiness by which you can generalize from your study to other people, places, events, and/or periods of time].
Just because you don't have to actually conduct the study and analyze the results, doesn't mean you can skip talking about the analytical process and potential implications.
Thus, the objective here is to convince the reader that your overall research design and methods of analysis will correctly address the problem and that the methods will provide the means to effectively interpret the potential results.
Your design and methods should be unmistakably tied to the specific aims of your study.
Finally, an effective proposal is judged on the quality of your writing and, therefore, it is important that your writing is coherent, clear, and compelling. This is where you explain the context of your proposal and describe in detail why it's important.
Trinity Western University; Writing Academic Proposals: Conferences, Articles, and Books. In general, a compelling research proposal should document your knowledge of the topic and demonstrate your enthusiasm for conducting the study.
A good strategy is to break the literature into "conceptual categories" [themes] rather than systematically describing groups of materials one at a time.
Note that conceptual categories generally reveal themselves after you have read most of the pertinent literature on your topic so adding new categories is an on-going process of discovery as you read more studies.

Since a literature review is information dense, it is crucial that this section is intelligently structured to enable a reader to grasp the key arguments underpinning your study in relation to that of other researchers.
