The TAU Systems survey analysis suite is a fully integrated menu-based system that runs under any Windows system (or MSDOS), designed to automate all functions of a market research company or any organization that performs surveys, and reduces total staff needs to two or three.
The system is free to educational bodies. The U.S. version has both English and Spanish language modules. Other latin-alphabet languages are available.
The system can generate and print several kinds of Optical Mark Readable (OMR) questionnaires, in many formats, on any WORD-compatible printer (for photocopying or offset printing) of single or double-sided pages to eliminate data entry costs and errors. OMR coding sheets can also be generated and read.
* The use of OMR is only an option to normal questionnaire generation.

TAU-SAP generates survey reporting source programs in TAU-SAP, IBM-SAP, and Quantum, for any formats from the questionnaire itself, and can convert any data formats (binary, IBMª, Quantumª, Excelª, various ASCII, and so on) to any other data format. Existing survey questionnaire formats can also be converted.
It features validate/modify data entry modes and powerful editing, checking, re-coding and frequency analysis modules (for both binary and ascii data files), has 15-dimension factor analysis, and conceptual mapping and standard statistical packages. It has a unique ability to process and code text replies automatically, and also offers CATI and CAPI services, and HTML web-based forms, all in any Latin alphabet languages.
Reports can be output in most standard Windows RTF and other formats. Greek questionnaires have also been used. See "Frequently asked questions".
