Conducive to timely adjustment, to avoid major rework. In the research and writing process of graduation thesis, the author's thinking activity is very active. Some unremarkable materials, seemingly irrelevant materials, often produce new associations or new viewpoints after being familiar with and thinking. If you don't write an outline carefully, you will be disturbed by this phenomenon, and you will have to keep writing, rethinking and even overturning what you have written. This not only increases the workload, but also greatly affects the writing mood. The outline of graduation thesis is like the blueprint of the project. As long as you carefully consider the outline before you start writing and spend more time and energy to make it solid, you can form a clear and logical paper framework, thus avoiding a lot of unnecessary rework. In addition, if the students who have just started to write a thesis write their own ideas as an outline first, and then ask others for advice, they can understand them at first sight, and it is easier to put forward some suggestions for revision and supplement, so as to get effective guidance.
