Coordinating all the complex behind-the-scenes details of staging a play is the task of the production manager. They are tasked with overseeing the crews for the sets and props, the sound and music, the lighting, and the costumes, ensuring that all the needed elements, facilities, and equipment are not only available, but are in good working order, properly catalogued and labeled, and safely stored from one rehearsal to the next, up until the time of the performance.
