Could a shared production checklist catch conflicting versions of audio, video and stage requirements before load-in?
Compare an owner-approved production brief, equipment list and run sheet by version and requirement ID.
What we could measure together
Measure: Late technical requirement changes after the approved brief (changes/event).
Freeze eligible work, observation window and acceptance criteria with the owner; retain incomplete work and exceptions.
Acceptance boundary: Never infer electrical capacity, rigging safety or venue approval; qualified staff retain those checks.
