What is the most common method used to assemble or shift scenery on stage?

The most common method used to assemble or shift scenery on stage is the use of a stage crew, which is a group of people who work together to set up, move, and remove scenery during a theatrical production. The stage crew is typically led by a stage manager or technical director, who is responsible for coordinating the work of the crew and ensuring that the scenery is moved safely and efficiently. The stage crew may use a variety of tools and techniques to move scenery, including dollies, trucks, lifts, and rigging.
