The basic purposes of all research proposals are to convince the reader that:
(a) the research project has clear objectives;
(b) the research project is worth doing (it is significant / important in some sense and will make an original contribution to knowledge / understanding in the field)
(c) the proposed methods are suitable and feasible;
(d) there is a well thought through plan for achieving the research objectives in the available timeframe.
Note that it is not enough to simply describe previous works, your project, and your methods
