Start with paragraph jobs
An outline becomes useful when it records the work of each section, rather than a list of broad topics. Begin with a working main idea. Under it, name the steps a reader needs to follow before the conclusion will make sense. A paragraph might define a problem, explain a reason, interpret evidence, or answer an objection.
Add evidence and explanation
For each body section, write three short notes: the main point, an example or piece of evidence, and the explanation connecting that support to the point. If you can name the evidence but not the explanation, you have found a question to work on before drafting.
Do not force every section into the same length. A complicated objection may need more space than a simple definition. The outline should help you distribute attention according to the argument.
Use the outline again during revision
Read only the main points in order. Does each one prepare the reader for the next? If a later point explains a term that earlier paragraphs already depend on, move that explanation forward. If two points repeat the same work, combine them or make their purposes distinct.
After drafting, make a reverse outline: summarize what each actual paragraph does in one sentence. Compare that with the original plan. Revise the plan, the draft, or both. A useful outline remains a tool for thinking, not a contract that prevents a better idea.
Try the idea.
In a draft of your own, write a one-sentence job description for each paragraph. Which paragraph repeats a job or has no clear one?

There is no single correct outline. A useful self-check names the paragraph’s contribution and identifies at least one possible change, such as combining repeated points or adding a missing explanation.
