It is always a good idea to make an outline before you begin writing a speech. An outline is a structural plan that lists main points, summarizes claims, and serves as a guide for the writing process. Working from an outline can help you organize your speech and put supporting elements, such as definitions and supporting evidence, in order.
Some outlines are minimal, providing a quick sketch of a speech's main points. Other outlines are very detailed, filling in a skeleton of topic headings with topic sentences, pieces of evidence, and transitions.
Many students are familiar with outlining techniques from academic writing classes. Outlining a speech is similar, but there is one key difference: speechwriters can use the outlining process to create prompts to aid with delivering the speech. Some speakers like to use handwritten notes, others use cue-cards, still others read from a printed script, and some experienced speakers don't use any prompts at all.
Ideally, with practice, you will avoid reading a script word-for-word— burying your face in papers for the entirety of the speech will limit your ability to engage the audience. However, minimal prompts such as cue cards and outline-style notes may help you stay on topic and remember main points. Whether or not you plan to use prompts, creating an outline is a great way to refine your argument— and you can always ignore it once you begin writing.
Many speakers like to brainstorm before making an outline. Brainstorming, which involves techniques such as creating "idea maps" or flowcharts that connect ideas and evidence, is less formal and structured than outlining.
It is a great place to begin if you're having a hard time settling on a definite plan for your speech.
A topic outline is a hierarchical list of a speech's main points. Topic outlines tend to use keywords and short phrases rather than complete sentences.
A topic outline is fragmentary— it serves as a prompt, rather than a draft of material to use in the actual speech.
A sentence outline expresses the central ideas of a speech in complete sentences.
Sentence outlines are more detailed than topic outlines, but less detailed than first drafts.
