So what so you think ERP stands for?
Well, there are several hundred things for which that acronym is used. But NOWHERE is there any explanation of which of them this poll is about.
I think that's appalling. So I decided ERP must have started off as the acronym for the People's Revolutionary Army (of Argentina) and and been adopted as project name (after all it's pronounceable) for a business expansion programme because the ERP were the first scheduled customer (and a brand new customer) for a shiny new weapons suite.
That response will be easily detectable (the "other" answers are designed to identify it pretty obviously) and can be eliminated from any summary of results. But what of the responses that take ERP as any one of the dozens of IT department relevant ERPs that you might mean instead of as the one that you do mean? Your audience don't know what they are being surveyed about - but each member of the audience will think she does.
This survey - because of that one stupid omission - is possibly a pointless farce.
