For non-majors who need to collaborate with development staff, or developers who have never worked at a somewhat organized IT company, it seems like a good idea to learn about the overall development flow and common sense of an IT company. However, the materials in Notion and the lecture materials do not match up well, and the sound varies from lecture to lecture, which is a disadvantage. Except for the two cases mentioned above, it seems like you don't have to listen to it.
