How do you map out your stories?

Hello writers!! I would like to know your process of writing. Do you journal it all down? Do you take small notes here and there and then go through them at a later date and compile which ones would be a good way to go?

Personally I love to jot down notes, ideas and character ideas whenever I’m brainstorming future books and if it rings to me at that specific moment I will try to make up an alluring storyline and plot through that way.

I really don’t know if that made sense to some, but I would absolutely love to know your thought process, how you map out and create your stories or books. Thank you all for your time!!
