Do You Write a Book From Beginning to End?

Do you write a book from beginning to end? Or do you write your plots out of order and then piece them together. What do you think it's going to take for publishing to make material changes in regard to diversity, equity and inclusion? Publishing houses need to change adn there's a reticence. People are not wanting to give up the power they have as publishers, as editors, as publices. I'm working on a book now that i'm goingto inee to just sit and read out loud and and figure out what’s happening and what i need to fix.
