It depends on what the school advises. Many dissertations have an introduction, literature review, methods, results, discussion, and conclusion.
But maybe you are not even doing a dissertation that requires "methods."
It all depends on what your school recommends.

Can you interview people? If so, read all about grounded theory and get started. As soon as you read about grounded theory and then maybe read an article that uses grounded theory (search the library database for articles with the words "grounded theory" and "literature review"), you will be ready to start.

About the debate, I think you need to find some other books and articles about this subject. Do you know what I mean? You can only contribute to a conversation if you know what people are saying. So... start by reading a few recent articles. That is the trick. By seeing what they do, you will know what you should do.
