Producers are divided into many departments. Life producers are managers who manage the life and logistics of the crew, eat, drink and sleep. On-site production is the discipline of on-site management to ensure the smooth creation of the main creative department; The producer is the manager who manages the production and display of the scenes of the crew (in the previous film studio, the producer was also responsible for the shooting plan of which crew); Outreach producer, as the name implies, is the manager who contacts the crew to shoot the scene outside (just like the public relations department of a unit); Each production department has a production director, and the production director has an executive producer (some directly face the producer, and the executive producer is between the production director and the producer). There are several spectators, all of whom are people who do some concrete things. The people in the production department do not participate in the whole artistic creation of the crew, which is equivalent to the logistics department of a unit.
