Snowflake method checklist. Maybe you'd rather work from the top down than from the ground up. Inspired by fractal geometry (really!), Randy Ingermanson's "snowflake method" grows an entire novel from a single sentence. Each step of the process methodically expands upon the one before, filling in detail until you have a complete draft.
A novel has a lot of moving parts. When you factor in research, articles saved with Web Clipper, and random jottings about who did what to whom, you'll probably find you have a lot of notes for your writing project. Consider adding a couple more to keep it all straight: a dashboard where you can manage the whole thing, and a checklist for bringing your completed opus to the world.
