I tend to make and carry more paperwork than I need, but, so far, it's never been more than the production needs. The fifteen extra minutes on the computer is worth it, to me, when a designer/director/actor/crew member can ask me a question or to chart something for them, and I can take ten seconds and pull exactly what they need out of a binder. This has also led to the practice of keeping two-volume "show bibles": one binder that is just the pre-show check list, script and post-show check list, and the other containing all other paperwork.
I look at my paperwork sort of like I do the contents of my kit. I might not need the Tide-to-Go pen every production (OffTopic: Those things SMELL!) but when it is needed, having it will save tons of time and headache. Same thing with some of the more obscure pieces of paperwork. Besides, with a computer and spreadsheet program, cut and paste is my friend, and I can work up anything in ten minutes from the basic pieces. Better to take the ten minutes in pre-rehearsal prep week, when you have it, than ten minutes in tech week, when you're near to pulling out your hair!
