Here is what Soton's Writing Skills centre say (also can be had in Word format):

Put it in writing on paper from the start:
You need this at the start:

http://www.sotonsom.com/theses/thesis_plan.jpgAs the dissertation process continues, I get reams of un numbered pages (evidence that the student did not bother to proof read a printed version), rambling discourses on the $, on the credit crunch or on some other very broad topic. You cannot do a dissertation on a borad topic for the simple but obviously not obvious reason that it is too broad. You are supposed to be adding value and that is normally done in small steps on a small and localised topic. These screeds on the $ or whatever often lack academic sources (if you cannot cite recent academic articles, then you are failing to show that you are building on the evidence/facts generally already agreed upon).
So, first off, you should trawl through Google Scholar or some other appropriate search engine/source and identify the topic you intend to research. To begin, make the topic broad: mergers & acquisitions, value at risk, etc etc. Then collect appropriate academic articles and data and ensure you can do the methodology the published articles used. If you have academic articles, relevant data and if you can do the methodology, then you are in a good position. Your finished article will be a replication of those earlier articles and, though probably not earth shattering, will be in the ball park; it will, in other words, have a similar standard to the published work.
Often, students begin a dissertation and, much later, they find they cannot collect the relevant data. By beginning all those processes at the earliest opportunity, you avoid having those problems later on when, they stand a much higher chance of mucking up your timetable.
