Editing Stage management (section)

== Regional differences ==

=== United States ===
In the United States, ''stage manager'' is a generic title that may be applied to anyone who performs stage management functions. On small shows, one person typically performs all the tasks of stage management, and is simply referred to as ''the stage manager''. Larger shows often need two or more stage managers. In such cases the head stage manager is titled ''production stage manager'' (commonly abbreviated PSM), and working under the PSM is one or more ''assistant stage managers'' (commonly abbreviated ASM). Shows that employ three stage managers have a PSM and two ASMs, though the program credits may list them as ''production stage manager'' (first or head stage manager), ''stage manager'' (second stage manager), and ''assistant stage manager'' (third stage manager).<ref name=Fazio />

Some professional stage managers on plays and musicals may choose to be represented by a union known as the [[Actors' Equity Association]], which also represents performers. In addition to performing their typical stage management duties (e.g., maintaining the prompt book and calling performances), Equity stage managers are also required to uphold the union's rules and rights for Equity artists. Union stage managers for opera, ballet, and modern dance are represented by the [[American Guild of Musical Artists]] and perform most of the same duties as their counterparts in plays and musicals. The [[American Guild of Variety Artists]] also represents variety performers, dancers and stage managers. Any show that is employing members of these unions must hire at least one stage manager that is also a member of that union.

===United Kingdom===
In the UK, the structure of a stage management team depends on the type and size of the production. It can consist of stage manager (overseeing the running of the show), deputy stage manager (commonly called DSM), and assistant stage manager (commonly called ASM). A [[fringe theatre]] show may employ one stage manager to carry out the tasks of an entire team, whereas a [[West End theatre]] show in London might employ multiple ASMs. Professional stage managers are represented by the [[British Actors' Equity Association]], which also represents performers.


====Deputy stage manager====
The DSM prompts actors and will usually cue technical crew members and sometimes cast, while following the orders of the director and stage manager. The DSM calls actors to hold while technical problems are sorted out during rehearsal, and determines where in the script to restart halted scenes.<ref>Pallin, p. 81</ref> The deputy stage manager (DSM) is a separate position in some theatres, while in others the responsibilities of the DSM may be assumed by the stage manager or assistant stage manager.<ref>Bond, p. 15</ref>

====Assistant stage manager====
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.<ref>Bond, pp. 15–16</ref> The assistant may also be in charge of one wing of the stage, while the stage manager is on the other wing.

===South Korea===
Due to the recent global rise in popularity of K-POP and mainstream cultural arts, Korean stage planners are playing a significant role worldwide. Typically, stage planners determine the timing and venue of performances and take responsibility for the entire process leading up to the completion of the event, acting as overall directors. They conduct thorough analyses on what performances people desire, whether similar events have already taken place, and if the emotional expression aligns with the intended message. Successful performances are scrutinized for the strategies used to captivate the audience. Those responsible for bringing the performances planned by stage planners to life on stage are the staff. Consequently, stage planners organize various staff members responsible for directing, choreography, music, stage design, lighting, costumes, makeup, etc. They also oversee the preparation process, secure the necessary funds, check preparations, and guide the director in staging scenes.


One of the most notable Korean stage planners is Kim Sang-wook, the CEO of PLAN A, who has orchestrated numerous performances, including the 'Love Yourself' tour by [[BTS]].
