Using an outline to guide your writing

The last point that I wanted to make about the pre-writing stage is using outlines to guide your writing. There are several types of outlines that you can use, and all will help you to organize your information, results, citations, and more into a useful writing tool. Armed with your outline you'll be able to ease into the writing process. Examples include listing, idea mapping, and freewriting. But, my favorite is using a traditional written outline formatted following the layout of an academic article (introduction, methods, results, discussion). Do you write an outline to help guide your writing?
