When a filmmaker starts filming he has to think of organizing his film well in advance. It helps when there is a filming plan with the location of where the film is going to be shot, the actors that have to be there and the time that certain scenes are going to be shot. There may also be a list of scenes so that the actor knows what to recite. Props may be listed next to the scene that would allow the director then to match the actor and the props he has to use for a specific scene. There is more to organization that just following a master plan.
When the novice filmmaker starts he has to see what professional people he is going to work with unless of course this is a student film and there is no budget for professional staffing or the filmmaker decides to work with his classmates to produce a project for a term project. Professional or not, ideally the filmmaker should respect the people he is going to work with in order to get moving smoothly.
I once found myself on a set equipped with a volunteer and then the producer decided to throw shit at the staff for having kept the production going into the wee hours of the morning. That negative discourse was counterproductive because it created resentment among the actors too who were required to stay awake longer than planned. So the filmmaker should keep to his schedule even if that means spending the extra money to keep the location for another day.
