There is no required list of paperwork.
Like a rehearsal report, that lists everything that comes up in rehearsal, the performance report is just the way of keeping track of run times, fixes needed, etc, etc. I use it as an all purpose of paper trail. (Wait until you are typing performance report #1872 for the same show . . . )
We have found it useful over the course of future seasons to look at understudies going, crew outage issues, etc, etc for data collecting. It's nice to be able to say for 16 shows the light board operator was out sick, for 7 shows this equity actors was out due to this conflict, etc, etc.
