Hi All *
Like most of you, I work in the software arena. However, I've recently been asked to organize audience evaluations for audiovisual productions as well (potentially film, TV, DVD, etc.). Some are training productions, some are persuasive, some have an entertainment component (though that is never the primary motivation for productions in my case).
I've done a quick web search, and most script evaluation seems to be of the "expert review" type ("pay me lots of money and I'll tell you where it stinks").
