How does the production and publication process differ for American comics and Japanese manga?

American comics are typically produced by a team of creators, often with a writer, penciler, inker, colorist, and letterer working separately. Publication is usually in monthly comic book issues, later collected into trade paperbacks. Japanese manga is often the work of a single author (mangaka), sometimes with assistants. Publication is primarily in weekly or monthly serialization in magazines, with chapters then collected into tankobon (paperback volumes). This serialized format influences pacing and story planning.
