This lecture was easy and quick to understand and apply thanks to the systematically organized content and various class materials. I prefer to study by saving each lecture note separately on my laptop without using Inflearn lecture notes. While taking this lecture, I studied by drawing along with the visual materials such as the design process and comparison of corporate development methods, which were not provided separately as class materials. I think the learning efficiency would be higher if visual materials of important content were also provided as class materials. Thank you for providing a good lecture.
