The snowflake method for novel writing has generated some discussion on rec.arts.sf.composition. It definitely does’t work for me (I can’t plan much at all), but parts of it work nicely for organizing revisions between drafts.
Basically, the idea is to start with a one-sentence overview of the book, and gradually expand it into a scene by scene outline, generating synopses of various lengths along the way. Eventually you write the book. If that sounds appealing to any of you, have a look. If it sounds completely alien, avoid it. (I’m avoiding it – it’s not possible for me to get past step 2.)
