– Introduction – What is development / design method

I will describe from my own knowledge and my own point of view. These contents are not the best way for all of this. There are various ways according to the situation. Moreover, there may be contents which stick to because they are looking at from their own point of view. I would like to think about a better method and I would like you to tell me if there is any problem.
