Theatrical production management is a sub-division of stagecraft. The production management team (often consisting of a production manager and any number of assistants) is responsible for coordinating the various sub-disciplines (scenic, wardrobe, lighting, sound, etc.) of any large theatrical presentation, as well as overseeing the stage management team. In most professional theaters the production manager is the highest ranking person on the production staff and answers directly to the general manager and or/artistic director.
Production management also deals with the logistics of the production itself, such as the procurement of rehearsal space and the booking of the theater. The production manager's job is rather fluid, however, and may also include just about anything an enterprising producer or director may dream up. Usually, though, the production manager's job is mainly supervisory, although it requires excellent 'people skills' in order to smooth over disagreements that inevitably arise.
