The assistant stage manager (ASM) has varied responsibilities, which are assigned by the stage manager. The ASM assists in finding and maintaining props during rehearsals and the run of the show. The ASM may take attendance or estimate audience size, may manage the backstage technicians, may act as a liaison between crew, cast and management, and may call some cues. Mundane tasks such as mopping the stage and brewing coffee or tea may fall to the ASM. If the stage manager is unable to perform his or her duties, the ASM must be able to fill in. The assistant may also be in charge of one wing of the stage, while the stage manager is on the other wing.
