This is a final year project. I have written a literature review on paraffin and after that, I wrote a case study based on the subject and I have missed one part which is the methodology. The methodology describes the broad philosophical underpinning to your chosen research methods, including whether you are using qualitative or quantitative methods, or a mixture of both, and why. It should be clear about the academic basis for all the choices of research methods that you have made. Also, it is a link between the literature review and the case study. Hopefully, this is clear enough for you to start.
