I want to redesign a website and write a document explaining my design approach and thought process. I have recreated the layout and explained my suggested changes. I have the content for the document but it's all unorganized. I have also listed service based websites which I feel have created good user interaction with their layout and design.
Can anybody suggest what points I should keep in mind, or to be precise, what should be the sub-headings of the document in order to make sure that I have covered all the necessary aspects of design and also to structure the content? It would be best if there was a template or an example design document.
