This refers not only to seamless management of the technical aspects of a production, but of the human aspects as well.

The responsibilities and duties of Stage Management vary depending on the setting of a production, i.e. rehearsals or performance, and the type of production being presented (theatre, dance, music).

Once the house opens, the Stage Manager essentially takes control, calling the cues for all transitions (this is known as being "on the book", the book being the script in which the cues and blocking are written), as well as acting as communications hub for the cast and crew. This function is referred to as Prompt.
