Example: an onstage actor dropped his prop, earlier this week, which was a wireless mic he was pulling out of a stand. It happens, human beings are fallible and we drop things, from time to time. A look at anyone's drinking glasses cabinet at home will confirm that. This was the only time it has occured.
But I was really tempted not to include it in my report, because my producer tends to think that one dropped prop is evidence of a continuing underlying problem that needs to be fixed. "The mic stand must be rigged wrong and the mic must be slippery. We can add some clamps on the stand and grip tape on the mic and maybe add more light in that scene so he can see the prop better!" when the reality is, the mic and stand and lights are fine; it was just an accident, a clumsy moment. One dropped prop out of six weeks of show.
For instances like that (nd really, in general when things go wrong), I'll put after why it happened and how it was fixed OR needs to be fixed. IE
"Jason forgot to turn off the radio in II.vi- Meghan got it later in the scene. "
"One worklight was on TOS...Cat turned it off, and I held the blackout longer to let actors enter."
This tends to appease people, as they know it's not a big deal.
It's interesting you brought this up, because I'm ASMing a show, and the SM doesn't put many things in the performance report that I would. She doesn't tend to watch the stage (granted, it's a cue-heavy show, but I was surprised!) and ends up missing things that happen onstage and doesn't put them in the report. Boggles my mind.
