Functional Show Stopper comes as one parameter of 'Priority'. I know Show Stopper.. but what is Functional Show Stopper ? What kind of issues can be categorized under this ?

At what point is this term used? During Requirements Review, development or testing? – MichaelF Aug 8 '11 at 13:27
This term is used during bug reporting ie. after testing. – Balaji Kothandaraman Aug 9 '11 at 9:25

This sounds like, to me, simply a "shop term", something someone came up with in a particular location or locale. A quick Google search didn't really find much of anything to categorize this term or define it in a global way.

So, a "show stopper", as I understand it, is a bug that makes the software product and/or feature being released critically unstable to the point that releasing it would cause the application and/or feature to be just a load of useless bits sitting on the hard drive. So, a "functional show stopper", while it might not totally trash the application, would mean that the bug gets in the way of the intended functionality in such a way that a particular function or feature does not meet requirements and is even un-usable in it's current state. It might not completely destabilize the application but it essentially will mean that the designated feature of the application might as well not be there.

I'm guessing "shop term" is a "shop term" that you came up with in your particular location or locale? :-) A quick Google search came up with nothing but offers to buy life insurance. – corsiKa Aug 8 '11 at 17:48
You're funny, @glow, but looks aren't everything. ;-) – TristaanOgre Aug 8 '11 at 17:51
I'd admit that it may be used only by my organization. We category issues as F.Show Stopper which works in other way fails to do its intended purpose, but is a show stopper issue. For eg. interest amount calculation is wrong in leap year. I just want to know whether this term is widely used everywhere. – Balaji Kothandaraman Aug 9 '11 at 10:45
Never heard of it before, and it seems I am not the only one. Many terms are localized or shop terms, its just a matter of figuring out which. – MichaelF Aug 9 '11 at 12:52

I'd agree with Tristaan that "functional show stopper" sounds like a term that your organization uses for internal tracking purposes.

I'd suggest you start by asking people you're working with for a clarification of how you're expected to use the term. It could mean anything from "this function is unusable" to "this is a show-stopper bug that is triggered by a function" (compared to a "performance show-stopper" like "it takes half an hour to load the application and data entry is accepted at a rate of one character every two seconds") (Don't laugh - I've had to work with applications like that...)
