By organizing your ideas you will create a clear picture of the structure of your paragraph. The most efficient way to organize ideas is to outline them. With the aid of an outline you will be able to decide if you have enough supporting ideas for your topic sentence and you will be able to eliminate those details that do not support your topic sentence. The outline will also let you test various methods of organization to decide which one suits your topic sentence the best and let you test the placement of your topic sentence within the paragraph to see where it will have the greatest impact on the reader. With the use of an outline you should be able to create organized, coherent, unified, well-supported paragraphs.
