Fable
Two stages and front-row inspectors
In the city there was a large theater that had to suspend performances for three days to rearrange the stage every time a new production came. Audiences made wasted trips, the troupe sat idle, and the box office stood empty. The director, pained by the losses, had two identical stages built. The new production rehearsed, tuned, and ran through the full process on the new stage, and once ready, the entire audience was led over to the new stage overnight while the old stage immediately rested.
This method is very reliable, not afraid of a failed scene change, and can bring all audience members back to the old stage within three minutes. But two stages mean double the wood, curtains, lamp oil, and set labor. A small theater troupe simply cannot afford it; only a large theater can operate this way.
Another theater used a completely different method. For a new play, it sold tickets only for the first three rows, leaving the other seats empty. After watching, the first three rows gave reactions: some complained the plot dragged, some pointed out that the lines could not be heard clearly, some were unhappy with the ending. The theater revised overnight, the next day released tickets for the first six rows, collected another round of feedback, and revised again. Only when most people nodded did it release tickets for the whole house.
Front-row testing is cheap and does not require building two stages. But the first three rows of the audience bear all the risk, and sometimes they get so angry at a half-finished product that they demand refunds. The theater must be prepared for compensation and communication, and some fatal problems cannot be found by the first three rows either — for example, when a large audience enters simultaneously, the aisles may clog, but the first three rows only have a few dozen people.
The two theaters' approaches each found their own uses later. The large theater had stable revenue, large audiences, and high compensation for accidents, so it used dual stages for safety; the small theater had a tight budget, flexible programming changes, and a small audience it could communicate with, so it used front-row previews to save costs.
Later the city issued a safety rule: plays involving stage structure changes or open-flame props must use a double stage, and the first three rows must not test risks for others; plays that only change scripts and lines can use front-row previews. The scenario determines the strategy; no strategy is inherently better.
An old director summed it up simply: the dual-stage approach is valuable for safety, while front-row previews save on flexibility. Which to choose depends on whether a failed performance costs applause or lives.
The troupe leader later divided performances into two kinds: only when an entirely new play changed scenes were both stages used; for changing a single lyric or a piece of stage movement, first let the ten old patrons in the front row hear it before scaling up. Small prior test. Stable.
