Re: Big demo. Should we test?
Like me going in to do a demo for a very large trading company, only to find that the only projectors they had were circa the turn of the millennium and only supported a 640x480 VGA display. Their desired configuration on the desktop was two 22" DVI connected monitors. It didn't go well.
Or the time we went to demo the software to another oil company. This was a web-based document management software. But they would not provide us with a PC or laptop, refused to let us connect to the wifi, and the building was Faraday shielded to block cellphone signals. That demo didn;t go at all!
