I'm a novice in architecture. Now I’m reading Clean Architecture and I don’t understand one thing. I'm wondering at what stage should I create components? Before any design or when I already have some design and implementation, something like this:

P.S. It seems to me that the answer is somewhere in the middle. Components are designed to separate classes into groups so that different teams can develop them independently.
