The most basic stage for conducting a research proposal is the identification and formulation of the research problem. This involves clearly defining what you want to study and why it is important. The first step is to identify a research topic by choosing a broad area of interest. Next, you conduct preliminary research by reviewing existing literature to understand what has already been studied and to identify gaps. Following this, you define the research problem by narrowing down the broad topic to a specific problem or question that your research will address. Finally, you formulate research questions or hypotheses by developing clear, focused, and researchable questions or hypotheses based on the identified problem. This foundational stage sets the direction for the entire research process.
I believe the most basic stage for conducting a research proposal starts with the researcher identifying an area of investigation he or she is enthusiastic about. Research takes time, energy, concentration to just name a few draws on the researcher. Find something that you feel passionate about to stay happily engaged. Then follow the steps outlined by Souad Selmi. Somewhere you will need to decide if you are going to do a qualitative or quantitative study. Qualitative studies are particularly good when there is little information about a topic. Years ago in healthcare, we were directed to talk with unconscious patients because they might be able to hear, but there was no proof of that. I interviewed 111 previously unconscious patients (Sometimes I get carried away when I'm very interested). Sure enough, some could hear and understand what was being said around them but just couldn't talk or move. Find your interest!
The first stage is to think of an idea, an issue that seems interesting and intrigues you. This comes from practical problems if you work, for example, or from others' experience. In that case, that identified issue would be in a raw state, you have to polish it ,i.e., to see what is the underlying scientific concept. An idea may also come from literature in a certain area, or even your personal concern. If you have nothing in mind at all, try to have a look on calls for papers/chapters issued by journals and books editors. Additionally, check the future research section in articles you read. This may open your eyes on some interesting topics.
I believe that the very first stage in conducting a research is that, you need to have your interesting research topic before you proceed to your goal. After that, design your statement of the problem, for it will become the umbrella of your study. :)
Read recent literature and studies and findings related to your interest. It doesn't matter if you do or do not have a particular topic in mind. It will naturally emerge when you read as much papers as you can. :)
