In a theatre, the front of house manager is responsible for welcoming guests, refreshments, and making sure the auditorium is set out properly.
By contrast, back of house (BOH) refers to any operations that are not visible to the audience, such as props management, costume design, stage set fabrication, lighting control, and other support functions.
Examples include cooking, dishwashing, cleaning, shipping and receiving, maintenance and repairs, accounting, and other indirect support tasks which are not usually visible to customers.
From this position they have unobstructed listening and a clear view of the performance, enabling the operation of the main speaker system, show control consoles and other equipment.
