In two linked posts, NY Times Bestselling author Jennifer Crusie posts a NaNoWriMo-riffic rough draft, and two days later posts about her process for analyzing the scene for revision.
Jo Walton and other smart people discuss it here on her LJ. I’m in there talking, too.
Personally, I do something very like this when I have a scene that doesn’t work but I can’t figure out why. I don’t normally think in terms of antagonists and beats, though. I usually examine scenes by the character goals, the resources it needs/introduces, and the work it’s supposed to do.
I hadn’t considered the concept of “frames” before–I think I’m going to steal that one. As for identifying the antagonists, well, in the Twenty Palaces books, pretty much everyone is an antagonist. It’s identifying the non-antagonists that gives me headaches.
