If you don't know what a business plan is and want to see it as a reference, I recommend this lecture. I think this is a very good lecture for beginners because game planning is a rare lecture material. However, if you assume that following the title of the lecture means that people understand and proceed with the work, not copying and pasting, then you should consider purchasing this lecture. Since most of the lecture content is reading the material as it is, rather than thinking that I can make a business plan after listening to this lecture, I think I saw a good portfolio.
