answer:Fiction or non-fiction? When I’m writing something for work (decidedly non-fiction), whether it’s a one page report or a ten page research, I diagram the points I want to make and how I want to get there. Even a technical report is, to some degree, telling a story. Once I know my milestones – the points and decisions I have to make, then I do my writing. I never write fiction, so I can’t speak to the efficacy of diagrams for that purpose. I would imagine they could be useful,but I have no experience.
