An outline should be made as a "preparation" of the official speech, so it should be written in a formal, clear and coherent language. In addition, the outline should be separated into sections to facilitate the division of the subject into parts and categories that allow the discourse to be more organized. When you divide your speech into categories you will realize that you have divided the categories into topic and subtopic, in which case using the example shown in the question "claim" is a topic and "introduction" and "supporting details" are subtopics, just as "counterclaim" is a topic and "supporting details" and "refuted points" are its subtopics.
