All jobs get easier with access to the necessary tools. In the case of academic writing, this means having the right guidelines, templates and samples so that your work looks the way it should. This is especially true when it comes to the completion of a dissertation which is generally the last major assignment you complete before graduating from a course of study.
Long before you reach to that stage, you will be expected to justify your intended project by completing a proposal for presentation to a panel. This must be done well or your work will be rejected without question. Here are a few places you can start your search for a sample in this vein:
People who frequent these types of forums tend to have an interest in writing well formatted and styled academic documents. They will therefore be likely to devote most of their conversations in such an arena to the exchange of ideas that lead to the creation of good work.
By using a search engine you can find many results almost in an instant. They may not all suit your purposes but some of them undoubtedly will. By using those you can tailor them to meet your needs and create a proposal that reflects your intended work.
If other people in your class have to write dissertations they will also be looking for the bets possible ways to propose their research to a panel and not get it rejected outright. Ask them to see the resources they have managed to put together thus far. Whatever they have done, you can learn from and whatever you have amassed they can also share. This method of community learning makes the class less selfish and more likely to succeed in the long run.
There was a class that finished doing exactly what you are doing now a year earlier than you. Seek those people out and ask to see the documents from their proposals. They may be able to stop you from making mistakes that are completely unnecessary by providing not just their samples but a running commentary on what worked, where and why.
There is no fool proof way of preventing errors in your work. The methods listed above will, however, reduce your chances of making big mistakes.
