There's one disadvantage to an organic outline writing technique. It's that you can get to following some character so intently that you forget to come up for oxygen and thinking -- hey what about the other POV characters?
I'm working on an outline now where the story is rife with dramatic irony. Usually, when I come for oxygen I can think of a way where another POV character is misinterpreting what goes on, or a scene where I can show that this one misinterpreted something. But I can also think of a couple of scenes that would logically have occurred earlier, since I'm writing this story in chronological order. (Thus far.) Which is not helped by the fact that I write in longhand. (With gel pens in pretty colors. My muse finds them an inspiration.)
But it can still be interesting in the manuscript, when I realize that I have to add another POV thread. Scuttling back and forth in the manuscript to ensure that the scenes get slotted in suitable locations. . . .
