Fable
The theater turned prompt writing into a testable rehearsal program
The South City Theater hired many actors skilled at improvisation. The director arranged them through cue sheets: this line must be rigorous, that line must be brief, and when evidence appears, cite the source. The new play grew more and more complex. One actor rewrote questions, one actor looked up materials, one actor inferred the case, and one actor wrote the reply. The cue sheets were scattered everywhere. The director first tuned the wording by feel. Add a line today, delete a line tomorrow, and add a rule whenever a bad example appeared. After several rounds, no one knew which line was useful. He then posted the best examples on the wall. Some tasks improved, others worsened; after new actors joined, they had to figure it out all over again.
The new director switched to a rehearsal program. Each role declared inputs and outputs, modules were connected according to the program, and results were measured with evaluation sets and metrics.
The prompt sheet no longer relies on handwriting alone. The rehearsal meeting will search for more suitable lines, examples and pacing based on examples, evaluation scores and role structure.
The theater began arranging complex performances like a fixed set of tricks. Change one role and old scenes can be replayed; swap one set of examples and score changes can be seen.
The director also did not give up judgment. If metrics are chosen wrongly, data is too scarce, or the task definition is vague, the optimizer will lead the system in the wrong direction.
The new director didn't throw away the cue sheets, but placed them in the rehearsal book. Every time a line was changed, it had to be test-performed on the same set of plays, recording which act worked and which didn't; if a line saved only one scene but hurt three, it was withdrawn and re-staged.
The rehearsal book also let the theater stop fumbling in the dark when swapping actors. New actors took the stage according to the role's inputs, outputs, and scoring method, and the director then adjusted the stage cue sheet based on audition results. Experience moved from the director's head into rehearsals that could be repeatedly tested, and the production stabilized. Later, when the theater took on new plays, the director first wrote roles and scoring, then arranged auditions. Changes no longer piled up from on-the-spot inspiration, but entered an inspectable rehearsal procedure; good and bad could be compared, and experience could be reused.
He finally understood that a complex production cannot be sustained long-term by the director's feel alone; it needs a clear role structure and a rehearsal method that can be measured repeatedly.
