Winsteps and Facets are complex statistical measurement packages. New features are continually being added, but backward-compatibility to earlier versions is also maintained. For Winsteps and its predecessors, this goes back to 1985. For Facets to 1987.
Winsteps and Facets are both Windows-native software packages, taking advantage of many of the user-oriented features of Windows. But, for "production line" analysis, Windows can get in the way. Accordingly Windows features can also be bypassed.
All this means that there can be a somewhat steep learning curve during your first two or three analyses. Rasch theory can be an unfamiliar way to conceptualize your analytical problems. The program user interfaces are more complex than "point and click", though more "point and click" features are continually being added.
Consequently, the entire software manual, called the "User Manual", is in the program Help files, together with plenty of example data sets.
Customer support is also available free by email. Most problems are solved by means of a line or two of explanation regarding Rasch theory or program operation, a simple suggestion, and a reference to a section in the software Help file. If the problem is due to a program bug, then a "fixed" version of the software is provided free by download as soon as possible, and a work-around is suggested until that time.
Response to most emailed questions is provided within 24 hours, usually by Mike Linacre, the software developer.
Mike Linacre uses the software himself to analyze real data. He also monitors the professional literature looking for useful new ideas and approaches to incorporate in the software. Suggestions and requests from users are frequently the source of new software features.
