Our products undergo a series of peer and technical reviews before each release, where each and every change is reviewed and tested for conformance to the design, as well as unintended interaction with other features. Each of the calculations in the software has been methodically verified for accuracy. We continuously track customer problems and suggestions, and integrate these into timely development solutions. These methods have been an institutionalized part of our culture for over twenty five years.
Our customers consistently rate our software an exceptional value for ease of use and functionality. Our free technical support and development efforts receive the highest ratings for rapidly responding to customer queries; assisting in statistical interpretation and analysis; and thoughtful involvement of customers in implementing improvement opportunities.
