Concept development document.
Your journey of development. Talk in the document about all of the original ideas that you had, or the narrowing down of your idea. Third person passive. Before you try to write always make sure you know what it is you are trying to say. After you refine your ideas you will have an idea of content and structure. Thinking of your timeline chronologically will help you recall your journey better, as you can see the order and influence of each thing you did. At each stage in the chronological milestone, you should discuss each point in a hierarchy, with the most important parts first. Create a timeline of your project subject from the first stages till now, for example, start at Jack Foley to modern films and everything important in between.
