Writing is a recursive process which sometimes is, but most often isn't orderly and linear. The writer may jump back and forth, write fragments and then put them together, start writing the end of the story and then return to the beginning, etc. It is never a straight forward process, but a dynamic and creative one. The ideas keep emerging, buzzing, and developing until the final version is done.
