Anyone know if great enterprises (Google, Oracle, SAP) uses Functional Point Analysis to estimate software building effort?
The IFPUG Membership Survey will tell you a little bit. Still, when I see a company like "IBM" in that survey, I am guessing it is Global Services (their consultancy). Maybe some product teams use it but most of the members of this organization at least are consultants / service providers who are selling The Methodology along with Their Services.
I worked for a fairly good-sized pharmaceutical company that used it, but that's the only time I've seen or heard of it used. It seemed like a reasonable methodology to me, but rather time-consuming and probably expensive (the guy who analyzed my systems was an external IFPUG-certified consultant).
