Drafting and production schedules are more important than one may think in the world textbook publishing. At the same time, deadlines can be burdensome for authors. Missing them is a principal cause of marketplace failure. An untimely textbook, finding no uncommitted customers by the time it reaches them, is doomed. Furthermore, postponement—pushing back a product another whole adoption cycle—is usually not a good option.
The best way to deal with schedules is to master them at the very beginning through realistic planning, starting with a drafting calendar.
