A useful timeline names both deliverables and decisions: outline approved, manuscript draft complete, edits reviewed, cover direction chosen, files proofed and publication date confirmed. Give each stage an owner and a realistic window instead of treating every task as a one-day event.
Add review time and a small buffer for revisions. If a milestone slips, adjust the sequence rather than compressing essential editing or proofreading. Regular check-ins give authors and publishing partners a shared view of progress without turning the creative process into a source of pressure.
