As your research and writing develop you will want to revise and rework your structure.
Try to review do this on a regular basis and amend plans for future chapters as you become more aware of what the thesis must contain.
Time spent thinking about and planning how you will structure your thesis is time well spent.
Start to organise the material that you have already written into folders relating to each chapter.
The literature review is something you will return to throughout the process of writing the thesis.
It will change in scope and length as you refine your topic and start to uncover findings.
People have different preferences in terms of writing.
Think about the approach that will work best for you.
The basic format of a thesis is, usually, an intro chapter, methodology chapter, lit review, data chapters, analysis, conclusion. You might not keep to those word counts, but it gives you something to aim for. Chapter 2: Methodology (or not, if you’re putting that somewhere else). There are basic formats on Google and most of them will work for you, with a bit of tweaking. [Unless you’re writing about rocket science.] Your other chapters will be less specific.
[If you keep to those word counts, more the better though. Google will probably stop being helpful around about the time you get to your data chapters, because each thesis is so individual.
