The quality of the lecture is really good, and it seems like the content is easy to understand. In particular, I really liked the way you explained the definition of requirements and the planning document, which were similar to real-world situations. Also, the practical tips you shared while doing the code practice were very valuable. The only thing I would like to see improved is that if this good content were documented more clearly, it would be easier for even beginners who are completely new to development to learn. Thank you for the great lecture.
