I have used this and can set up a demo if you would like to see it in action. I can setup a gotoomeeting in about a minute and we can go over some of the features if you like.
You can send me an email to gerald@weldingdata.com if you want more details.
Some features of the WPS program are
Built in code checking for ASME Sec IX and D1.1
Very easy creation of a prequalified WPS
Up to 3 processes per pqr/wps
Ability to combine multiple PQRs for one WPS
Etc...
The WPQ program also has built in code checking for Sec IX and D1.1 and can provide continuity reports, expiration warnings etc. The ability to search for qualified welders can also be useful.
I'm not a Cspec employee but do work very closely with them and provide services to them.
There are also a couple of videos at
http://www.weldoffice.com/video/ that show some documents being created.
