Your dissertation essentially involves two elements: the research project and the research report. The purpose of the report is to tell people about the research that you have done. The examiners’ assessment of the dissertation will be based partly on the quality of the research and partly on the quality of the report. However, the examiners have to base their assessment of the research on what they see in the report; they don’t have much else to go on! This means that you can make a mess of a perfectly good project by writing a duff report on it. However good the quality of your research, you rely on your report to communicate that quality to the reader. A weak or careless write-up could waste all the effort that you put into the earlier parts of the project. The aim of this chapter is to help you to make the very best of your project by producing the best report you possibly can.
