The macro checklist: chapter by chapter
Work through your manuscript chapter by chapter and ask three questions of every scene: Does this scene have a clear goal for the POV character? Is there genuine conflict that stands in the way of that goal? Does the scene end in a way that complicates the character's situation rather than resolving it cleanly? Any scene that fails all three checks is a candidate for cutting or combining. Any scene that fails one or two checks needs structural surgery before line-level editing begins.
