When I was writing macros in Lotus 123 and Excel and writing Standard Operating Procedures (SOPs) we called "beta tests" gorilla tests. Like Matt we would take someone who knew nothing about computers to test the macros and someone who knew nothing of the SOP object (machine operation, testing procedures, etc) to try to run/operate it by only using the SOP. You learn very quickly how difficult it is to write/program things like that.

PS - I was the gorilla on a couple of SOPs!

Whenever I get something stuck in the back of my throat, I dislodge it by drinking a beer.
It's called the Heineken Maneuver.
